Topic: Undelivered Mail Returned to Sender

Hello, i recently using relayhost with my ISP smtp as a relay, when i send mail to yahoo or another mail domain displays the following error in mail.log:

postfix/smtp[3701]: DD6882FBD1: to=<username@yahoo.es>, relay=smtp.relayhost.com[192.168.2.1]:25, delay=0.1, delays=0.05/0.03/0.01/0.01, dsn=5.7.1, status=bounced (host smtp.relayhost.com[192.168.2.1] said: 550 5.7.1 <username@yahoo.es>...

Seems your ISP doesn't allow to relay your emails. You should contact ISP to get support first.

I have a MDaemon mail server working properly. I am trying to migrate the MDaemon mail server to iRedMail, with MDaemon i can do relay to my ISP host with authentication, but not with iRedMail, i think i have something wrong in the configuration file, i have no idea what happens, any suggestions please?

thanks...

Re: Undelivered Mail Returned to Sender

I beleive its relay isseu from your server to Your ISP server,you should ask your ISP to allow relay from your server to there server.

I have already made contact with my ISP provider and he gave me a host (smtp.relayhost.com) and a user name and password of an account MultiPOP to do relay.

Then in the main.cf file:

relayhost = [smtp.relayhost.com]
smtp_sasl_password_maps = hash:/etc/postfix/sasl-passwd

in the /etc/postfix/sasl-passwd file:

[mail.example.com]           username:password

Then I made postmap to sasl-passwd file:

postmap hash:/etc/postfix/sasl-passwd

It does not work, still gives me the same error:

postfix/smtp[3701]: DD6882FBD1: to=<username@yahoo.es>, relay=smtp.relayhost.com[192.168.2.1]:25, delay=0.1, delays=0.05/0.03/0.01/0.01, dsn=5.7.1, status=bounced (host smtp.relayhost.com[192.168.2.1] said: 550 5.7.1 <username@yahoo.es>... Relaying denied. Proper authentication required. (in reply to RCPT TO command))

I do not know if I'm missing some configuration, or is that iRedMail does not allow relay to the ISP host with SMTP AUTH???

thanks in advance for the help...
