kandi X-RAY | smtpd Summary

smtpd is a Go library. smtpd has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

smtpd is a go package for handling the server side of the smtp protocol. it does not handle high level details like what addresses should be accepted or what should happen with email once it has been fully received; those decisions are instead delegated to whatever is driving smtpd. smtpd's purpose is simply to handle the grunt work of a reasonably rfc compliant smtp server, taking care of things like proper command sequencing, tls, and basic correctness of some things. (the standard library net/smtp package handles only the client side of smtp; it makes no attempt to provide the facilities you'd need to write a server.). smtpd sort of comes with a 'sinkhole' smtp server that simply takes in email (perhaps) and doesn't do anything with it beyond perhaps writing it to disk. this is obviously not suitable for production usage but it does make a potentially useful sink for spammers (which is what the author uses it for). this once was cmd/sinksmtp.go, but has become so large and complicated that it has moved out to its own repository, because of its origin as the core engine of a sinkhole smtp server, smtpd is pretty casual about a lot of things in the smtp protocol and in what information it hands to higher layers; for example, it basically ignores smtp parameters on mail from and rcpt

This command: gcc file.o -o a.out does not link to a python library.

You need to add (append) -lpython3 and possibly -L${CONDA_PREFIX}/lib/python3.9 to it.

globalfun postfix/smtps/smtpd[24656]: warning TLS library problem: error 14094418:SSL routines:ssl3_resl3_read_bytes: tlsv1 alert unknown ca:../ssl/rec/layer_s3.c:1543:SSL alert number 48:

Your client refuses to connect to your mail server since it does not trust the CA which issued the mail servers certificate. It notifies the server about this problem by sending a unknown ca TLS alert.

There can be various reasons for this. Typically it is either the use of a CA which is not trusted by the client which need to be fixed at the client (trust this CA) or at the server (use a certificate from a CA trusted by the client). Or the root CA is actually trusted but the server is not sending the intermediate certificates needed by the client to build the trust chain to this trusted root CA. This need to be fixed at the server.

PEAR Mail in php:apache Docker container

Asked 2021-Jun-07 at 05:37

I have two servers. A Postfix mail server with Dovecot that, otherwise, works fine. I can send mail through it using Gmail client (So, yes there is a valid certificate installed there). The other server is my app server, which has the php:7.4-apache image running. I've installed the PEAR Mail library into that container/image, and I'm trying to send mail from the app through the mail server, but the PEAR Mail client keeps hanging up after it sends STARTTLS.

So, turns out, when I updated my certificate locations when I changed the method of acquiring them (certbot vs acme.sh), I got a typo in one of the filenames. /etc/dovecot/conf.d/10-ssl.conf was correct and so was /etc/postfix/main.cf, but /etc/postfix/vmail_ssl.map had a typo which I didn't see previously - and so was throwing a certificate error.

Postfix not receiving mail. Helo command Unauthorized

Asked 2021-Mar-03 at 14:41

OS: Ubuntu 12.04

Mail version: Postfix 2.9.6

The sender is able to receive emails from us, but the emails are not showing up in our mailboxes, and I do not understand why.

ANSWER

Answered 2021-Mar-03 at 14:24

I found it! In /etc/postfix/helo_access.pcre, there was this regex pattern:

/.*\.co$/ DISCARD Unauthorized-2015-240

which matched the message in the logs:

Helo command Unauthorized-2015-240

So I added regex to allow that specific domain:

/.*o1.ptr3680.wellable.co$/ OK

then reloaded Postfix and the emails were received upon trying again.
