Hello
I was able to send emails until I have changed the hostname and since then all emails are become “Unrouteable address”, I have checked the hosts and the new hostname is valid, also I tried several email relays but still same error.
Outgoing email or incoming?
Outgoing emails
check the exim mainlog for more informations
no host name found for IP address
dovecot_login authenticator failed 535 Incorrect authenticat
Hi guys, Do you have any solution?
Please provide with more information:
no host name found for IP address
dovecot_login authenticator failed 535 Incorrect authenticat
Is not useful to debug anything:
Send a email and check then the last 10 lines of /var/log/exim4/mainlog
