[...] The copy I receive from the list does not verify correctly here, either. It seems somewhere along the path the e-mails content is actually mangled. -- some additional newlines are introduced compared to my local copy from the "Sent" folder which verifies correctly. Attached are `sent.txt` (and `sent.eml`) and `received.txt` -- the very same e-mail as seen in my Sent folder and Inbox respectively... Interestingly, if I split out the signatures and message contents, I get bad signature for both variatns despite the fact that the e-mail client can somehow verify the sent e-mail... ??? Linux-Fan
