Hi!

I run into problem in Exim 4.60

In exim.conf:
...
domainlist antivirus_domains = lsearch;/etc/exim/antivirus_domains
acl_smtp_data = acl_check_data
av_scanner = clamd:/tmp/clamd
...
acl_check_data:
deny    domains       = +antivirus_domains
        message       = Message rejected: malware found ($malware_name)
        log_message   = Message rejected: malware found ($malware_name)
        malware       = */defer_ok
accept
...

While receive a message, I have this error message in mainlog:

temporarily rejected after DATA: cannot test domains condition in DATA ACL


Can I use "domains" condition in acl_smtp_data?
I didn't found answer for this question in spec.txt.

If no, how can I solve the problem?
Without "domains" line it is works fine, but I want to turn on antivirus scanner only for special domains.


If it is an entire source or 'from' domain you wish to select on, simply use the acl earlier (HELO or Mail From).

If you wish to defer the action to be taken until the data phase, set a flag in an acl-c(n) (entire connection) variable, and test for it at the later (data) phase.

If, OTOH, it is one of your own 'incoming' destination domains (presuming you host several), that you wish to select on, then check the $domain portion of each incoming *message* address against a list.

$local_part and $domain of incoming messages remains directly available from first appearance until delivery completes.

FWIW, you should probably scan *all* incoming for WinCrobes.
The best-maintained WinBoxen still become infected. Even Mac's, *N*X boxen, or otherwise-immune OS/2 can onpass.

HTH,

Bill
