[AMaViS-user] Endless loop after virus detection

[Christian O. <og...@MA...>]

Hello,

i've got a problem with AMaViS 0.2.1-pre3 (and it's still the same with
0.2.1).

I am using the option --enable-relay=yes to scan incoming, relayed and
outgoing emails.
The scanning itself works fine, but as soon as it detects a VIRUS i get
the following situation:

- the SENDER of the email gets a notification (which is ok)
- an email is created with "-Y" as SENDER, which is first sent to root.
  afterwards it creates an endless loop 'cause the user -Y is unknown
  (of course ;)) and bounces back, and so on...

/var/log/mail looks like this:

sendmail[27657]: JAA27657: from=<se...@gm...>, [...] proto=SMTP,

I am using the configuration described in the several README-files of
the distribution.
The command 'causing this loop seems to be (/etc/sendmail.orig.cf):

Mlocal,         P=/usr/sbin/scanmails, F=lsDFMAw5:/|@qSPfhn9, S=10/30,
					R=20/40,
                T=DNS/RFC822/X-Unix,
                A=scanmails -Y -a $h -d $u

'cause if i remove the "-Y" (A=scanmails -a $h -d $u) i get a similar
result, just with "-a" as sender... ;)

I tried several configurations, but always got the same result.
Maybe someone know what's going on?

Any help is appreciated!
