Re: [Exim] Questions using transport filter

Hi Patrice

I'm not sure if I understand this right. When will this condition be
matched? I have to call my programm for every outgoing mail there is. It's
not clear to me who sets the value for $received_protocol to encrypted and
under what circumstances. If it is set if the mail is sent/received using
TLS, this would be the wrong approach.

On a second note: if it makes it easier I might also switch to Exim 4. I
checked the online documentation, but didn't find anything appropriate
there as well. Can you give me a hint how it is done in exim 4 and what to
look for in the documentation?

Thank you
