Dear all,

does anybody of you send outgoing emails to a smarthost via SMTPS (port 465)? I tried to set the port of the outgoing smtp smarthost temporarily to 465, which resulted in a log entry of

Sep 3 09:56:26 myserver postfix/smtp[12792]: CLIENT wrappermode (port smtps/465) is unimplemented
Sep 3 10:00:35 myserver zmconfigd[5599]: Var zimbraMtaRelayHost changed from 'smtp.mydomain.com:465' -> 'smtp.mydomain.com:587'

I don't know if the mails are sent over an SSL channel now or not. Any hints are highly appreciated!

Thanks in advance,

Martin
