Subject: Re: [Exim] Using transport filters on the SMTP transport
Ahhh... I get exactly the same thing on Exim 3.12 using a transport filter
that removes "dangerous" attachments. It worked on earlier versions of
Exim though. I've confirmed that this is not the filter's fault by
substituting it with 'cat'...

This a bug or a change in the way Exim handles transport filters that I've
not picked up on?..
