Are you getting a 'mail transport unavailable' error? If so, post the relevant mail log entries (eg. what transport is it referring to?)

Jesse Norell · Aug 24, 2016

smtp-amavis: connection refused
Click to expand...

probably just need to restart amavis, or troubleshoot why it won't start if that's the case

tashman89 · Aug 24, 2016

10025 is postfix, try restarting it (postfix stop; postfix start). Or maybe just restart your server, which should catch everything.

tashman89 · Aug 25, 2016

thanks dear I did restart for my server many times but no luck

till · Aug 26, 2016

Your master.cf contains the config for port 10025, so postfix should listen there. Have you tried to restart the whole server, maybe postfix is hanging and does not react on restart? If a server restart does not help, check which "netstat -ntap | grep 10025" if postfix really listens on that port.

change "no_unknown_recipient_check" in your master.cf to "no_unknown_recipient_checks" and restart postfix.

tashman89 · Aug 26, 2016

Many Thanks florian030 when changing "no_unknown_recipient_check" in your master.cf to "no_unknown_recipient_checks" the problem has been solved and I can send and receive email normally also thanks dears Jesse Norell and till I appreciate your support and helps
