You'll have to build dbmail with debugging symbols
(CFLAGS+=-g)
You also better build dbmail static (./configure
--enable-shared=no
--enable-static=yes)
After that you can create a txt file containing a sequence
of imap commands:

cat >> imapcmd.txt << EOF
1 login testuser1 test
2 select INBOX
3 fetch 1 (UID ALL)
4 logout
EOF

run the imap commands through a gdb wrapped dbmail-imapd:

gdb ./dbmail-imapd
gdb> run -n -f /etc/dbmail/dbmail-test.conf <
imapcmd.txt
*segfault*
gdb> bt

the test-scripts directory in the tarball contains a number
of imap
command sequences I use the test stuff.

I think the problem I'm going to have with this is the
"compile..."  
part.
I suspect that the problem is related to the .deb build
(it's  
compile) more than compiling dbmail on my machine.

However, I can try compiling dbmail from source on this
machine and  
first check to see if it's still causing a segfault.  But it
will be  
a couple of days before I can really dig into this.  I have
need to  
set up HTTPS first and then I'll have lot's of time
available for  
dbmail.
