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/smtpd[29529]: connect from unknown[12.34.56.78] Apr 13 17:31:44 ns1 postfix/smtps/smtpd[29529]: lost connection after XCLIENT from unknown[12.34.56.78] Apr 13 17:31:44 ns1 postfix/smtps/smtpd[29529]: disconnect from unknown[12.34.56.78] Im unsure of what I would need to do in nginx.conf. I placed xclient on; But also not sure of what my smtp_capabilities should be there: These are the current ones: smtp_capabilities "VRFY" "ETRN" "ENHANCEDSTATUSCODES" "8BITMIME" "DSN"; I also whitelisted the ip address in sender_access but I dont think this is enough. The problem is the host does not have a reverse dns setup so I think postfix is rejecting it? Thanks for any help
