Hey all,
I keep finding core dumps of the IMAP process on my FreeBSD 11.2, however the
backtrace is not very useful:
Core was generated by `imap: [xistence at 0x58.com
2601:282:4301:befc:1cfb:807f:e527:5a3b UID SEARCH]'.
Program terminated with signal 6, Aborted.

I am sorry that I haven't been able to find any more information or figure
out what is going on :-(
