but are they guaranteed not to be mangled by MTAs and the like? I regulary
see cyrus replacing some characters in Subject: and From: that it doesn't

That means for me that those headers are even less trustworthy than the

Erm - see mailsync.sf.net. If you want to synchronize mails between

Some are allways online, some are mostly offline etc.

Syncing mail allows me to have all of my mails wherever I might work.
