Hello @rigu,

Can you share the output from /var/log/exim_mainlog when attempting to send an email? EX:

exigrep "SUBJECT" /var/log/exim_mainlog

Replace SUBJECT with the subject of an email that you attempted to send out. Ensure to replace real domain names and IP addresses with examples when you paste the log output here.

Thank you.
