I'm having problems with spam for users who forge the sender to appear as one
of my domains. The spam is coming from an external mail server. Is there
anything I can add to my main.cf to combat this? Any suggestions are
appreciated.
smtpd_recipient_restrictions =
# allow password auth
I'm trying to debug a: lost connection after CONNECT error
I added the following to main.cf
debug_peer_list = [REMOTE_IPADDRESS]
Here is the following syslog entry. Does it show anything relevant?
Is there anything else I or the remote administrator can try?
postfix/smtpd[18377]: connect from
