Hm, maybe using zlib would help - but this would require a big rewrite of
part that calls gzip. However, if you simply "move mail" and not "move" a
folder not successfully copied mails will be kept in the old folder.

I think it's a problem of the pipe, eg. big mails (with attachment) need
more than one block in the pipe so gzip has a problem with it. But I don't
see why this could be a problem.

Another idea I just got:

gzip is started by fork(), what if the forked process is still running and
the next mail is written - both processes (the new forked and the old one)
write into the file. So maybe big mail causes gzip to take more time to
finish and the main program (xcmail) starts with appending the next mail.

Hm, this sounds good (or better: not good).
