Hi Everyone, I'm new here since I've decided to host my own linux server and try to configure it myself. So I followed a turorial on digitalocean combined with thing I have found here on howtoforce, step by step and just to be sure I checked everything again. The problem I have is that I'm able to receive mails, but I cannot send... Before I begin I need to say that I did all my installations with Code: sudo in front of it. Perhaps this can be important to know? The error(s) I get when executing Code: sudo service postfix status are Code: May 05 11:34:05 mailserver01 postfix/smtpd[4657]: disconnect from unknown[80.82.65.204] ehlo=1 auth=0/1 rset=1 quit=1 commands=3/4 May 05 11:34:53 mailserver01 postfix/qmgr[2906]: EA5792C0AAC: from=<[email protected]>, size=682, nrcpt=1 (queue active) May 05 11:34:53 mailserver01 postfix/qmgr[2906]: 650172C0BF3: from=<[email protected]>, size=405, nrcpt=1 (queue active) May 05 11:34:53 mailserver01 postfix/postdrop[4677]: fatal: /etc/postfix/dynamicmaps.cf: file open failed: Permission denied May 05 11:34:54 mailserver01 postfix/sendmail[4675]: warning: command "/usr/sbin/postdrop -r" exited with status 1 May 05 11:34:54 mailserver01 postfix/sendmail[4675]: fatal: [email protected](1001): unable to execute /usr/sbin/postdrop -r: Success May 05 11:34:54 mailserver01 postfix/pipe[4670]: EA5792C0AAC: to=<[email protected]>, relay=spamassassin, delay=7187, delays=7186/0.01/0/1, dsn=4.3.0, status=deferred (temporary failure.

Thanks in advance Peter
1. Check port 25 for sending mail, whether it is opened. Use a relay instead, if it is not opened. 2. Check you postfix config in main.cf and master.cf files. I think your destination should not contain your mail domain.
