Hi, I am trying to get a CentOS 6 system relaying mail via my G-Mail account. I followed the instructions found at https://www.zulius.com/how-to/set-up-postfix-with-a-remote-smtp-relay-host/but there seems to be a problem with authentication. I have done some research but still can't get this working. Any suggestions ? It seems the user and password are correct.

I read several posts about SMTP being blocked at ISP. My ISP has the same limitation. My ADSL connection (1 fixed IP) only permits outbound connection to port 25 to their server. None of those posts answered my need. I tried FAQ also. I have several internal email clients/bots that needs to retrieve/send messages, some of then...

Hi, my name is Julio Rojas and I've trying to get my Linux (RedHat 7.2) Email Server using Sendmail to use my NT Domain account database. To accomplish this we have tried with Winbind and it has worked for longins at the server and for POP3 authentication, but we haven't been succesful at SMTP authentication. All the emails sent to my Linux server are rejected with the message USER UNKNOWN. The following is an example of my NT server trying to send an email to my Linux server: SMTP (560) Trying aiur.uft.edu.ve (0) SMTP (560) Connect aiur.uft.edu.ve [200.35.85.219:25] (2) SMTP (560) 220...

Thanks for idea but it won't work for me as 'internal domains' can be anything, including gmail.com (and i don't know which of them are really internal/local, this is decided by sending SMTP everytime something is sent, based on MX records). Problem is that Dovecot/Sieve is using wrong SMTP server (one used for receiving e-mails which should NEVER be used for sending [and is never is, except sieve]).

Hi, in our setup, we have two SMTP servers: - one for receiving messages (this one is using Dovecot's LMTP for delivery) - one for sending messages (this one is used by our users as outgoing SMTP server) Only the first one has list of local domains, local e-mail accoutns etc. so the second one will ALWAYS use MX records...

...ication). I'm more interested in what happens after that. You'll need to enable mail_debug=yes (at least for the user involved) to get that. Regards, Stephan.
