Julian

Thanks. That would do the job. 

In fact your suggested way is better because the logged line will also
include the envelope-sender address.  

Note though that if people chose "Log HTML Tags = yes" and if they also
chose to strip HTML on, say, the occurrence of an IFrame tag in a
message then three lines will be logged:

Jan 18 04:03:29 cheviot4 MailScanner[29462]: HTML IFrame tag found in
message 
j0I43C12031986 from boston at changing_boston.net

Jan 18 04:03:29 cheviot4 MailScanner[29462]: Content Checks: Detected
HTML-specific exploits in j0I43C12031986

Jan 18 04:03:29 cheviot4 MailScanner[29462]: Content Checks: Detected
and will convert HTML message to plain text in j0I43C12031986

I am happy to live with that if it simplifies the additional coding you
have to do!

Regards

Quentin
