FWIW
If you are still interested in running UW imapd, you may want to look at
panda-imap instead.
[ http://en.wikipedia.org/wiki/UW_IMAP#Future_of_UW_IMAP ]
" Mark Crispin <http://en.wikipedia.org/wiki/Mark_Crispin>, the former
developer of UW IMAP,
announced^<http://en.wikipedia.org/wiki/UW_IMAP#cite_note-3> a fork
called Panda IMAP"
https://github.com/jonabbey/panda-imap
I've been using it for a while now, for my personal mail server.
Switching fixed a number of problems that I was having using that last
dist from UW.
Cheers

I had a similar crashes in imap-2007f running on SLES 11.3. I debugged

that resolved the crashes for me. I sent my patch to this list, but I'm

Even though I was able to fix the problem, I lost confidence in UW imapd

We have been running the UW-imap application for quite a while. First
on a Sun system and now we have upgraded [2011] to imap-2007f running on
a Centos system. I have noticed lately that imapd segfaults. I was
wondering what I can do to determine the cause or if this is known
