No, I don't use any PMail Plugin at all (you mentioned a PGP Plugin 
which would work well with PGP, not GnuPG. A many years old GnuPG 
Plugin exists, but is totally unmaintained, doesn't work well with 
attachments etc....)

I use GPGRelay with GnuPG 1.4.18; Pegasus talks (unencrypted, 
unsigned) with GPGRelay on localhost with port numbers, and GPGRelay 
acts as "local proxy" which talks with the POP3 and SMTP servers and 
signs/verifies/encrypts/decrypts the mails with GnuPG.

I would say (concerning GPGRelay/GnuPG) yes, because (standard 
answer) I did not change anything, not with Pegasus Mail, not with 
any settings in GPGRelay and it ran perfectly.

... OK, I will try this...

logs the _complete_ TCP/IP protocol (in this case between Pegasus 
Mail and GPGRelay) including the decrypted mail data... maybe it 
helps to see what happens last before everything stucks...

Similar logging exists for GPGRelay, and that is, where I see the 
last mail GPGRelay tries to retrieve from the POP3 server before it 
just hangs and where I found that it happens quite often during 
verifying especially your mails. That is, why I asked whether 
something on your signatures may be a bit "special"

Currently I have not the time to go much more in depth and can live 
with the fact that in that moment much other stuff on this computer 
tends to hang and the "easiest" way for now is to reboot... It is 
possible that this behaviour came with one of the last MS 
patchdays...

Thanks, best regards
Matthias
