Re: [clamav-users] PUA detected. False Positive?

2022-07-16 Thread Al Varnell via clamav-users 
I see you figured it out, but just to close this out...

As long as there is another entry on the next line, the a CR is OK. In your 
case ClamAV was looking for a second entry and not finding one it assumed 
malformation.

Re: [clamav-users] PUA detected. False Positive?

Apparently resolved by having *only* the signature name on the line.

I'm not sure there is a good way to do it only for that particular 
sender, unless you have a way to send those messages to a 
differently configured ClamAV setup. I don't do a lot of email 
scanning, so I'm not sure what the limitations are there.

Does that include CR at the end of a line?   Docs suggest multiple 
ignores in one file, each on it's own line.   Did I misread? (not the
