This sounds more like postfix problem.

Hi people,

 

Version of my beloved Dovecot installation:

2.2.27 (c0f36b0)

 

I moved from a OS X server to a Linux (Ubuntu) Headless server. All fun and good to play around with. Love almost everything.

In the combination with Postfix and Dovecot I’m stuck to despair into oblivion.

 

Everything works except I cannot send mail from my (OS X) Outlook client I keep getting:

 

Connection to the server failed or was dropped. Error Code -3253

 

Nothing More and nothing less. O do not get any other error in a logfile or anything. And I followed almost every installation manual I found. Postfix I can send and receive through telnet. But I just can’t get this to work…

The mail doesn’t even reach Postfix queue as I cannot connect to send. I do have a awesome connection receiving my mail though ☺

Anyway:

dovecot -n gives this (and I probably don’t see it anymore as I’ve been at this for several days now)

# 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf

# Pigeonhole version 0.4.16 (fed8554)

# OS: Linux 4.13.0-37-generic x86_64 Ubuntu 17.10

  }

}

Anything useful I would love to see. Any information needed.

 

THNKS…
