smtp Connection refused

clickwir · 23. Juli 2016

Trying to setup the notifications, have a webhost that has a mail server. But logs show I'm getting a "Connection refused".

Code

Jul 22 22:36:17 NAS postfix/pickup[15871]: 240C07F6: uid=0 from=<root>
Jul 22 22:36:17 NAS postfix/cleanup[19079]: 240C07F6: message-id=<20160723043617.240C07F6@NAS.localdomain>
Jul 22 22:36:17 NAS postfix/qmgr[5954]: 240C07F6: from=<notifications@mydomain.com>, size=434, nrcpt=1 (queue active)
Jul 22 22:36:17 NAS postfix/error[18947]: 240C07F6: to=<my@email.com>, relay=none, delay=0.12, delays=0.1/0/0/0.02, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to fltr-in1.mail.dreamhost.com[208.97.132.73]:465: Connection refused)

$ openssl s_client -connect mail.mydomain.com:465
Shows a nice handshake and gives this:

220 email.host.com ESMTP

So it appears I can make a SSL connection from the OMV box to the mail host, but postfix can't
I can get to the webmail of my host and login with the same username and password.

According to the host, use port 465 with SSL/TLS or 587 without. But both require authentication. I've tried several combinations of this in the Notifications settings and syslog still shows connection refused.

OMV 2.2.5

If I recall correctly postfix does not support using port 465 using ssl, you have to use another communication layer under that stunnel if I remember. Alternatives..... does the mail server support port 587 in TLS? or use a gmail accoung

Looks to be about the same with 587 and no SSL.

25 gives a time out. Probably blocked by comcast.
