Well, our SMTP server checks for virus. But this doesn't seem to work with
IMP (configured to use SMTP). 
It *seems* that PHP sends the mail regardless what the SMTP server returns.

Here's an example of the SMTP dialog:

... while talking to smtp.mydomain.org.:
>>> DATA
<<< 551 5.7.6 Virus/Worm/Trojan detected: [virus].(vscan.mydomain.org for smtp.mydomain.org Sun Jan  6 12:56:08 2002)
554 5.0.0 Service unavailable
554 5.0.0 savemail: cannot save rejected email anywhere

The other communication with the SMTP server seems fine - eg. I do get the
"correct" answer when specifying 

 unable to add recipient [@]: 553 5.1.3 <@>... List:; syntax illegal for recipient addresses
