dovecot_plain authenticator failed for and executable attachment "ForwardedMessage.eml
Posted: 08 Jul 2022, 23:35
I just move my clients to a new server.
I have dovecot and Exim
CSF and imunify360
I get a lot of emails about lfd on jds1.3aliXXXXXXXX.com: blocked XX.68.245.XX (US/United States/c-XX-68-245-xx.hsd1.xx.xxxxxxx.net)
T
His IP is also listed on: SORBS DUHL and Spamhaus ZEN
The IPs on the black list are my clients. and was wondering if there was something I did to cause it?
The machine IPs are clean.
Is there something I did as far as a config to get these messages?
I had to white-list him so he could get his email.
