Well as I've mentioned... on looses the info in the From_ lines (that is
the RCPT TO address and the date of arrival) because Evolution does not
correctly migrated them (actually I'm not sure whether IMAP would allow
that).

Sorry... too late for that... cause back in the "old" days when I went
away from TB I didn't notice that the used other mail headers for their
statuses... so now everthing is already mixed together.

Yeah... but sed alone is not enough... cause such lines may also appear
in the body... and I mustn't remove them...
So in principle I'm looking for a smart parser of mbox which already
gives me headers and body and I can modify either.


Cheers,
Chris.
