Cant send mail from proxy (postfix on backend)

2014-04-13 Thread cybermass
Hi. I set up an nginx imap/smtp proxy. I can see in the logs something about the proxy not being able to send mail. Apr 13 17:31:43 ns1 postfix/smtps/smtpd[29529]: warning: hostname host.domain.com does not resolve to address 12.34.56.78: Name or service not known Apr 13 17:31:43 ns1 postfix/smtps
