Postfix not sending email

Hey,

We have an Ubuntu 15.10 server running, we managed to get Postfix and Dovecot set up, however Postfix can not send any email to the outside world. We have checked around and tried a lot of different stuff, but still it is like that. Thanks for the help.

Nov 27 15:46:00 packer-ubuntu-15-10-amd64 postfix/smtps/smtpd[16693]: NOQUEUE: reject: RCPT from 524AC878.cm-4-3d.dynamic.ziggo.nl[82.74.200.120]: 554 5.7.1 <slash-vasko@mail.slash-it.eu>: Recipient address rejected: Access denied; from=<slash-matthew@mail.slash-it.eu> to=<slash-vasko@mail.slash-it.eu> proto=ESMTP helo=<[192.168.178.11]>

Any ideas?

Okay, I’ve hit the main.cf file and changed the smtpdrelayrestrictions, and deleted Slash-it from the my destinations part.

however, if I now try to send internal or external email through the Apple mail client. I get the following error. “cannot send email through mail.slash-it.eu” the error message reads “recipient address rejected: access denied”

Hello,

Please output your main.cnf and your full log file. This is probably being caused because you haven’t got the proper setup for a relay (for example in smtpd_relay_restriction)
