25.10.24 00:27, Sławomir Dworaczek via Exim-users:
recently I receive a lot of spam that looks like it was sent from my
address to my address
I added to the configuration:
set acl_m0 = authorizedrelay
deny
message = 5.7.0 You can't spoof the domains this server is authorative
for
sender_domains = ^(?i).*(mydomain.pl)\$
deny
message = 5.7.0 You can't spoof the MIME From this server is authorative
for
condition = ${if match
{$h_from:}{(?i)@([a-zA-Z0-9_.\\-]*\\.)?(mydomain.pl)}{yes}{no}}
condition = ${if eq {$acl_m0}{authorizedrelay}{no}{yes}}
unfortunately it didn't help
What else can I do?

We have this simple check:
accept authenticated = *
condition = ${if eq{$received_port}{587} }
control = submission/sender_retain
......
deny hosts = !+relay_from_hosts
domains = +local_domains
condition = ${if or{ { eq{$sender_address}{$local_part@$domain} }\
{ eq{$sender_address_domain}{$domain} } } }
message = The same local addresses or domain in MAIL FROM and RCPT
TO from nonlocal relay
