Thank you for the help with this issue. Filtering is running smoothly.
Attached is the Jérôme version of clamav.py, with the mail warning I
added. Maybe can be of some use to somebody there. In case you have
suggestions or improvements I'll be very thankfull if you let me know.
Enrique.

I'd use string formatting instead of concatenation:
text = "You received a message from '%s', which contained a virus." % who
message.set_payload(text)
mailServer = smtplib.SMTP('localhost:25')
mailServer.sendmail(sender, to, message.as_string())
mailServer.quit()
def doFilter(bodyFile, controlFileList):
# check for viruses
try:
pyclamd.init_unix_socket('/var/run/clamav/clamd.socket')
avresult = pyclamd.contscan_file(bodyFile)
except Exception, e:
return "554 " + str(e)
if avresult == None:
return ''
if avresult.has_key(bodyFile):
mail(courier.control.getRecipients(controlFileList),
courier.control.getSender(controlFileList))
return "554 %s was detected. Abort!" % avresult[bodyFile]
Right there, you want:
if avresult.has_key(bodyFile):
sender = courier.control.getSender(controlFileList)
for recipient in courier.control.getRecipients(controlFileList):
mail(recipient, sender)
return "554 %s was detected. Abort!" % avresult[bodyFile]
