Hi there
We are tracking an strange messages serie at Mail Queue (Proxmox Mail Gateway 1.7) that is hold on for delivery. Generally the sender are users from our domain but we have too many entries like that
- - - - - - - - - -
Deferred Mails for Domain 'ebgz.itownet.cn' (max 200 entries)
Date Time KByte Sender Receiver(s)
Fri Dec 21 15:50:01 7 MAILER-DAEMON fozzye@ebgz.itownet.cn
SMTP RESULT: connect to ebgz.itownet.cn[59.42.252.66]: Connection timed out
- - - - - - - - - - - -
The sender is MAILER-DAEMON????
The target domain is unusual for our users...
We accept no relay (I hope), no way to identify the sender... Is our security at risk?
Thanks in advace,
Juan Carmona
