Golang SMTP error: 535 5.7.0 Invalid login or password

Asked 2021-Jun-01 at 15:00

I'm trying to create emailing service with go. When i tried to send email via gmail or office365 code works just fine but when i tried to send email via custom smtp i get "535 5.7.0 Invalid login or password" error.

I know username and password is correct because i am using same password and username with another python service with flask-mail and other services works just fine.

I don't have any documentation for custom smtp server but i know smtp server uses TLS

I tried plain auth, gomailer, smtp.SendMail() function and without startTLS but nothing changed.

here is my code;

The error you get is definitely returned from smtp server. There are several authentication mechanisms supported by smtp protocol. If you do not know for sure which are supported by your server, you can debug it manually with the following command openssl s_client -crlf -ign_eof -connect :. After sending EHLO to the server it will announce supported authentication mechanism(s). Then you can try to login manually and implement Start() and Next() properly.
Notice that some methods require login and password to be encoded(base64, md5, etc).

Unicode Characters in Attachment name

Asked 2020-Jul-02 at 23:56

I'm trying to write a program that sends PDFs to my Kindle using SMTP.

When I send an attachment to the Kindle using a regular client (i.e. Outlook), I get the correct file name even if it's non-ASCII. However, when I send it using the code, the Unicode characters are not shown correctly. I tried sending the attachment to my personal email and there was nothing wrong in it, only Kindle does not recognize the characters.

This is my attachment headers:

RFC 2822 style email headers do not allow unescaped Unicode characters. You need to use an ASCII-compatible encoding, such as RFC2047¹ or RFC 2231, eg:

The error message Error: tls: first record does not look like a TLS handshake is telling you what the problem is :-). If you try connecting to the server, you will see that (as any SMTP servers) it uses plain text:

Firebase function for nodemailer deployed but no logs and not working correctly with database

I have setup a firebase-function with nodemailer to grab the input from my firebase-database connected to my contact form and email it to my email.

I have successfully deployed the function and can see the function showing up in my firebase console, however i do not receive any errors in the console nor see any logs or information in the function section of the console. And it just simply doesn't work right now.

As explained in the comment, since your Cloud Function is triggered by a background event, you must return a promise to indicate that the asynchronous tasks are finished.

So in the goMail function you should return the promise returned by the sendMail() method with:

How to set send-as email address using gomail

Asked 2019-Jun-05 at 17:06

I am trying to send email using gomail and need to set the send-as emailed address. I found the link to set the reply-to address, which is close, but not exactly what I'm looking for.

Send-as is a function that I know GMail supports, others prob do as well. I have send-as already configured in GMail itself and working correctly, just trying to see if I can set it via gomail

I have tried the following:

ANSWER

Answered 2019-Jun-05 at 17:06

The docs for the google api you linked do not talk about setting a mime header - there is no such thing as far as I can see. So setting a "SendAs" mime header on the email is not going to have any effect.

You are using gomail - the github repo for it states 'Gomail can only send emails using an SMTP server' - that means it's not using the api you have linked (which has nothing to do with mime headers).

What may work for you instead is simply setting the from address to the address you have already set up on your google account as a sender, and using gomail to send via your google account.

"Sendmail look alike" mode with-t removes Bcc: headers after processing them.
In -t mode Bcc: headers content will be appended to the (SMTP) recipients list BUT recipients will not see/receive Bcc: headers.

Style guide suggestion: IF you use another SMTP/MTA soft (e.g. Exim) in "sendmail look alike" (command line comparability mode) THEN use sendmail program/binary provided by them.

You cannot directly include index.js file in HTML and invoke the Nodejs function. instead you should be using Express framework at Nodejs and use jQuery to post the form data. Please follow the instructions provided in the below link: https://www.tutorialspoint.com/nodejs/nodejs_express_framework.htm
