Thanks. Went and diffed the complete messages as exported to disk ... and sure
enough, here we go:
# diff Message_Sent Message_Received
< Content-Type: text/plain;
> Content-Type: text/plain; charset="us-ascii"
< Content-Type: application/pgp-signature; name=signature.asc
> Content-Type: application/pgp-signature; name=signature.asc
Since this is happening through multiple smtp servers, it's most likely that
it is happening in kolab. I already shifted this over to their newsgroup ...
Thanks for your nudge,
