QUESTION
I've been made aware that aiosmtpd logs to the syslog. I'm using a Red Hat Linux distribution and can't find anything related to my SMTP server in the messages or maillog file. I'm trying to debug an issue with a device that can't connect to my SMTP server with basic authentication as I can't find any reason why the device is being rejected by my server. The only way I've been able to debug so far is by using the EHLO and MAIL handlers and printing a message when that stage of the connection is reached. Ideally, I'd like as much as possible to be logged out, like with smtplib that enables you to see each message between the client and server. Is it possible to do this or some basic logging at least and how do I do it if so? The code I'm using is:
...ANSWER
Answered 2021-Dec-07 at 18:41If you search the aiosmtpd codebase for "logging.getLogger", you can find a few places where logging is being configured with Python's standard logging module.
In order to actually see these log messages, you need to configure the log level and add a log handler. Try calling the following "configure_logging" function early in your program. It will set up basic logging to stderr and to a file named "aiosmtpd.log". Complete example:

I tried userinfo.property based task notifications and it works fine. But I'm stuck in sending notifications with DB users. I’m getting the below error.
23:49:35,378 ERROR [org.jbpm.services.task.deadlines.notifications.impl.email.EmailNotificationListener] (EJB default - 1) Unable to send email notification due to null
It seems to be coming from below line.
org.jbpm.services.task.deadlines.notifications.impl.email.EmailNotificationListener.onNotification(EmailNotificationListener.java:122)
I guess the system cannot load the user info from the DB.
I’m using JBPM 7.56.0.

getting error curl: (56) response reading failed
while trying to send email via smtp using curl. checked the isto-proxy logs of sidecar but don't see any error
logs related to this host. Tried the solution mentioned in How to access external SMTP server from within Kubernetes cluster with Istio Service Mesh as well but didn't work.

...ANSWER
Answered 2021-Sep-14 at 10:38Most probably port number is causing the error and if not, try deleting the mesh policies
Also please validate based on below points:
1.If you recently updated istio try downgrading it. 2.Look again in Sidecar logs for any conflicts or try disabling it. 3.When it comes to curl 56 error packet transmission; limit could be the problem.

QUESTION
When an e-mail message about to be send fails MTA-STS checks, it must not be delivered by design; will the sender be informed about the delivery failure? When?
Long & Background info:When implementing mta-sts on custom domains to enforce the use of TLS connections, misconfigurations of the mta-sts.txt policy file (or a smtp-server not supporting TLS connections) will result in e-mail not being delivered as an enforced policy will require TLS connections to deliver the e-mail.
Via TLS-reporting the domain holder - not the sender - could be informed about any problems, provided TLS reporting is set-up to a different domain or tool that notifies on a different address than the domain in question.
My question is about any senders of e-mail messages. In a testcase with policy file mentioning incorrect mx records, no e-mails are delivered (as expected), but the test sender did not receive any messages about delivery problems (yet).
Is this expected behaviour? Or will the sender be informed after a number hours? If so, how many hours? - I ask because a delivery failure and NDR (non-delivery-reports) are usually returned instantly.
If a user misspelled an e-mail address or the receving server is down, the sender is informed about the trouble and can take action. Sometimes even the "delivery is delayed" is announced; not failed yet, but not delivered either.
I get the impression that the sender is not informed that a message is not delivered and is "silently blackholed / discarded". To be clear: that the message is not delivered is expected behaviour in this test case.
...ANSWER
Answered 2021-May-12 at 09:47After running some testcases, I have experienced the following:
(This was done by a Outlook.com smtp server.)
Testcase C- MTA-STS: Deliberately incorrect, but existing third-party mx server in mta-sts file.
- DNS: Correct mx server.
The sender was informed about the delivery failure after 24 hours.
It was explained in my local language what was going on; here information highlights:
- That the message could was not delivered.
- That it was tried multiple times to deliver.
- But that the cause was being unable to connect to the remote server.
- Advise was given to contact the recipient by phone to ask the recipient to inform the postmaster about the error.
- It was even suggested that the problem could most likely only be solved by the postmaster.
- (A link was provided but that wasn't really helpful. Additionally the technical bounce message was visible among it the technical words "failed MTA-STS validation").
- MTA-STS: Correct and desired mx in mta-sts file.
- DNS: Deliberately set to incorrect mx server, existing server though.
After 24 hours I received an error back. Confusingly the message state that the address did not exists in the target domain. Though this is true, it shouldn't have gotten this far. However, when reviewing the technical part the outlook-sending server mentioned 'failed mta-sts errors validation'. So the technical part contained the correct mta-sts validation error, but the human/user readable part only mentioned that the target address did not exist in the target server.
I guess if the address doesn't exists, any mta-sts errors are "less important" to report to the end-user. The user was advised to re-type and resend the e-mail and verify if the address with the recipient (phone was mentioned). However, even if the user followed the instructions, the next e-mail wouldn't have been delivered either, but that is beyond this testcase.
Testcase A- MTA-STS: Correct mx in mta-sts file.
- DNS: Fake MX corrects.
After 24 hours I received an error back. The cause for not being able to deliver the message was being unable to resolve the domain location of the recipient. (Undesired result, but logical, mx were referring to nothing.)
The technical part of the message mentioned 'DNS query failed'. Nothing of mta-sts was mentioned.
Testcase Z (weird one)- MTA-STS: Correct mx in mta-sts file.
- DNS: Incorrect but existing mx records; a cname referring to the same IP of the correct mx server (which shouldn't matter because mta-sts should compare cert with cname.)
The results, unexpected:
- One email got delivered somewhere between that 24 time-window.
- One email failed due to mta-sts validation error.
Temporary downtime of webserver might have been a factor, though that shouldn't have mattered. - Cannot explain.
ConclusionI took a while to find the correct testcase as you can see. But Testcase C describes the desired behaviour. Yes, the sender is informed, after 24 hours with outlook.com as smtp-server. The user is informed in clear language. That being said, I do have an additional opinion about the timing here, mentioned below.
LimitationsStaying with the facts: I did not perform a testcase with a server trying unencrypted connections. Testcase C puts the ball into the the recipient's postmaster's court, I would be curious to see where the ball (the 'todo') would be placed, in the case of unencrypted attempts, as that cannot be solved by the recipient but must be solved by the sender or sender's postmaster.
I also did not test multiple smtp servers.
Further thoughtsThat being said, MTA-STS-validation needs to be supported by the sender SMTP (correct me in comments if I am wrong*), so if a server is so old it tries do deliver an e-mail over non-encrypted connection, it will most likely not support MTA-STS so it will not validate the MTA-STS policy and simply deliver the e-mail unprotected. * Found confirmation here, from paragraph "There is a standard...")
If somebody tries to redirect some incoming e-mail by dns-poisoning, a modern smtp-server will not deliver the e-mail to an incorrect destination. So it protects against evil doing, not against legacy.
OpinionI think the feedback delay of 24 hours is too long. Testcase C reports 11 retry attempts within that 24 hour window. Though I appreciate the system not giving up, I would argue that it might be in the interest of the sender to inform him of at least a non-regular delivery.
QUESTION
While trying to build an E-Mail client using JavaFX and Jakarta Mail, I wanted to implement a connection test to make sure that the credentials the user entered actually work for both the IMAP and SMTP server they specified. I have no problem with validating the IMAP credentials so far.
For my SMTP validation code, I searched the internet for a feasible approach, came across this question and implemented it in my project as follows:

Answered 2021-Mar-08 at 16:29Your servers are not configured to advertise the SMTP authentication extension (RFC 4954), judging from the EHLO response.
The credentials are then not sent by the client (as the server would not understand them anyway).
You should see something like this in the server's response:
QUESTION
I am trying to create a local SMTP server. I configured everything according to this: Link to set-up hmailserver
After that, I ran my diagnostics thing and it said host(in my case, noreply@bufferoverflow.com) cannot be resolved. I googled and read the documentation and question section of hmailserver Docs and found that I am missing a DNS configuration on my machine.
I followed this article to set-up the DNS ip to name: How to add ip domain mapping in windows
127.0.0.1 bufferoverflow.com
on my
C:\Windows\System32\drivers\etc>notepad hosts.ics
It still said host cannot be resolved to a type. I tried to see if the port was actually open and listening. So I did this command in CMD:
netstat -a
It's listening. I doubled checked everything but coudn't found where I was going wrong. I created a simple nodejs server and hosted it on port 80 at localhost and typed "bufferoverflow.com" in my browser it opened 127.0.0.1 aka localhost which is because it has an ip domain mapping I have given.
Now I am lost as why the hostname can't be resolved. My DNS is cool. Everthing is configured as docs says and the port is also open and listening. Please help me.
...ANSWER
Answered 2020-Nov-10 at 06:25So based on what you said you created your own SMTP server which is nice and all to learn, but I would recommend using SendinBlue 3rd party service FREE and gives you 300 mails/day
Getting Started with sendinblue:
Go make and an account free of charge till you decide to pay you'll read there
Once your account is all set, and activated often SMTP service for ones account is not automatically activate so you'd have to email them and they literally respond within 24hr I LOVE THE SERVICE(I am not promoting nor sponsored to hype them or anything just saying the truth of what I have experienced).
So now at this point your account and SMTP service is activated, now question is how do you use sendinBlue?
In your dashboard on your Top right you will see your username
Click on that and a dropdown menu should appear
Then you want to go to SMTP & API
Once you then you will see a menu with API Keys on the left and SMTP on the right
You want to click on the SMTP.
Once you the you will see Login that would be the email you registered with and you will see Master password now that is what you use to authenticate yourself.
Implementation: Now you have everything sorted you know where you keys are and login
In .env file

Install smtp-server
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
