You can set the $domain from RCPT in acl_m0 and then use logwrite $acl_m0
when virus is detected. Then you can also have logic for if you want to
overwrite acl_m0 if its already populated, leave it as-is, or append
recipients.
The reason $domain is not available in DATA is that a email can have
multiple recipients on the same server.

Ämne: Re: [exim] Access $domain in ACL?
Bummer, I see the $domain variable is not available. RTFM and I see the
following note:
15. Data for message ACLs
In the case of RCPT (but not MAIL or DATA), $domain and $local_part are set
from the argument address. The entire SMTP command is available in
$smtp_command.
That sucks, as I don't know who the recipient is the virus-infected message
is.
Yesterday tried to do my scan in the ACL, which works, and then log when a
message contains a virus in a router but there seems to be no way to write
to the log in a router. In the router, I actually do the scan of the virus
scan result and write the message to disk and stop processing. The message
is then picked up and placed in quarantine, so I thought writing to a log
at that point would be good... but can't figure out any way to write to the
log in the router. Is it really not possible, or am I missing it?
