How soon? With what kind of imaptest parameters? I can't reproduce
this on my Macbook (OS X 10.5.4, HFS+).
I ran imaptest for just a few minutes and saw all these errors in that
time. Default imaptest parameters except for user/host names etc.
Error: UIVALIDITY changed: %d -> %d
Did you test with a single user or multiple users? imaptest's
support for testing multiple users is currently a bit broken, but
this shouldn't happen with a single user..
This error happens with clients=1, clients=10 and clients=100.
Error: user%d[%d]: <...>: Header CC changed
Error: user%d[%d]: <...>: Header DELIVERED-TO changed
Error: user%d[%d]: <...>: Header FROM changed
These shouldn't be happening as long as you use a test mbox file
that has unique Message-ID headers. Were you using the recommended
dovecot-crlf as the input?
I passed in your dovecot-crlf file to imaptest, but the message store
was cloned from elsewhere first. So you're saying that dovecot only
works with special hand-crafted input, and not with real-world mail?
Hmmm.... :) :)
Actually I do see plenty of duplicate Message-ID headers in the mail
store (not from your input file). I'll investigate that further.
Thanks for the tip.
