I have set up an email server, but I have a problem with sending mails to Gmail.
This is my /var/log/mail.log:
Jun 4 20:49:26 jenny postfix/qmgr: 4CBDB67482: from=<mail@[...]>, size=627, nrcpt=1 (queue active) Jun 4 20:49:27 jenny postfix/smtp: 4CBDB67482: to=<[...]@gmail.com>, \ relay=gmail-smtp-in.l.google.com[22.214.171.124]:25, delay=1.6, \ delays=0.05/0.01/0.73/0.86, dsn=5.7.1, status=bounced (host \ gmail-smtp-in.l.google.com[126.96.36.199] said: \ 550-5.7.1 [188.8.131.52 12] \ Our system has detected that this message is 550-5.7.1 likely unsolicited \ mail.

Is there any server configuration I can undertake so that Google will find my ip not as spam sending?
