ISPConfig 3 DKIM not signing mails form externam client

Hi,

I have strange problem:

If I send mail via roundcube installed on ispconfig server, mail si signed with DKIM.

If I send mail from externam client (thunderbird, K-@ mail) mails are not signed with DKIM.

Instalation is Debian 8, with last updates, ISP Config version: 3.1.11 updatet with reconfigure services

Any TIPs?

 

Check your mail.log when you send a mail from thunderbird. Roundcube connects to the mailserver on port 25, so this should not be a problem. Usually, there is no problem with dkim-signing on port 25 and 587 with a normal setup.

 

Yes you are right, If I send via 25, mail is signed with DKIM, and I try 465 or 587, mail is not dkim-signed...
if send via 25,
by localhost (ispconfig.franz-net.info [127.0.0.1]) (amavisd-new, port 10026)
if send via 465 or 587
by localhost (ispconfig.franz-net.info [127.0.0.1]) (amavisd-new, port 10024)

any tip?

 

Are you sure, that followed the official tutorial step by step? this is working out-of-the-box.

 

It was new instalation of 3.1 (which included DKIM) and upgraded to 3.1.11.

 

Based on which tutorial?
