Hello,
after upgrading to 2.2.22 the lmtp service is crashing (segfault) a few
times per hours.
>From the logs:
Mar 19 16:37:29 lmtp(redac...@ruhr-uni-bochum.de): Info:
ohZXLe1x7VaUeQAAEc+Mrg: sieve: msgid=<redac...@async.facebook.com>: discarding
vacation response to mailinglist recipient <redac...@facebookmail.com>
Mar 19 16:37:29 lmtp(31124): Info: Disconnect from 134.147.42.228: Successful
quit
Mar 19 16:37:29 lmtp(31124): Fatal: master: service(lmtp): child 31124 killed
with signal 11 (core dumped)
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.
