i have found this in exin log
2022-09-13 14:35:09 1oY589-0006GP-KU [SERVER_IP] SSL verify error: certificate name mismatch: DN="/CN=node2.limonet.si" H="mail.ananirvana.com"
hmmmm ideas?

DN="/CN=node2.limonet.si" H="mail.ananirvana.com"

Did you change your hostname by any chance? Seems it's registered to SSL with the node2 name, but Exim is saying hello with a different name.

Did you use the ssl sni setting in directadmin.conf?

no i didnt...
server hostname and host for email is not same becouse i have multiple users/domains on this server
nod2 is my email servers hostname
mail.ana.... is domain from where the email is send (via php)

 

[mxroute]

Run this:

grep E1oY4w2-0003kT-8n /var/log/exim/mainlog

The answer should be in that. Feel free to post it if you don't think it's anything too private.
