But my ulimit (which is built into bash) wants you to specify the size 
in kilobytes.

Anyway, I have also done strace on the "imap" process and found some of 
the problematic messages.

I attach the output from strace (don't know if it's useful?) and the 
messages (there seems to be more of them, but I don't know how many or 
how long it would take to find them all with strace).
