Hello,
after upgrading to 2.2.22 the lmtp service is crashing (segfault) a few times per hours.

All those crashes have either a "send vacation response" or a "discarnding vacation response" in common.
I'll attach a backtrace and the current configuration.
I don't know why vacation would affect this, but these should fix the crash:
