clamd and tnef error?

[Randal, Phil]

I spoke too soon, the 0660 permissions didn't help here.

Setting 

Incoming Work Permissions = 0660

Does indeed fix it.

Jules, should this change in the default MailScanner.conf?

Cheers,

Phil

In a world where all winmail.dat files were generated internally, I would agree with you.... But since that is not the case, I would have to beg to differ...

I've been happy with the internal TNEF expander for years, but ...
some (business-critical, of course) emails couldn't be expanded -> couldn't be scanned -> ended up in the quarantine. Sigh. So I went for the external one, with good success.
AFAICT the problem is that the clamav group permission is 4, not 6. I fail to see the risk of allowing the group to be able to write as well as read.
I have my Incoming settings like:
Incoming Work User = postfix
Incoming Work Group = clamav
Incoming Work Permissions = 0660
,,, which work perfectly.
