dovecot send mail and receive mail

[arrn]

Using thunderbird mail. Running an mailserver local for 2 domains and 2 domains i host elsewhere on a sentora panel.
DNS all setup, mail A records and MX records point to the exernal server and mail server. Try to send a email via thunderbird, have in my local mail log, user unknow in virtual table. First at all no clue why it looks local, becouse there is nowhere any dns entry what points to this local mail server.

On the sentora server in the dovecot log file i have the entries below.

Any clue or hint are welcome

Sorry having trouble to understand the setup!

The local mail server is sentora too ? So you try to forward using the first server to the second?

no. server A is not sentora, i just host there local 2 domains and a postfix/dovecot mailserver for this 2 domains.
Sentora server is a dedicated external server. with 2 other domains. Nothing should or get forwarded.
domain A: points to the local server
domain B: points to the local server
domain C: points to the external server (sentora)
domain D: points to the external server (sentora)
DNS seems to be setup correctly. Using yahoo mail send mail to Domain C. and then in Sentora in rundcube i see the mail.
If I try to send mail via Thunderbird to Domain C, then i get a popup say, user unknow in local virtual table also can't reach Domain C: But this proberly haves to do becouse dovecot seems to crash on the sentora server.

So fact: first I have no idea why Thunderbird even thinks Domain C and D is local there is no DNS entry or IP or anything else what points to this local IP. ???
then no single clue why dovecor seems to crash on the sentora

The answer is domain E conflicting with Domain F! Man you are killing me.

IF dovecot crashing don't exepect to be able ever to connect.

Thunderbird issue is more likely your config settings. As long webmail works this is on thunderbird side.

not just killing you, im close before the point i drop death also. I think i give it up also, remove the sentora and setup all from hand at least then i know whats going on, in most cases
