I've been unable to leave Xymon service tests for imaps and pop3s enabled for a long time, because they intermittently fail, leaving Xymon's view of the service in flapping state.

I found these this evening:

https://groups.google.com/g/linux.debian.bugs.dist/c/Gg0ZQHSDQ2g
https://salsa.debian.org/debian/xymon/-/merge_requests/1

I think this might address my issue. Any chance you could add this to the Xymon builds in pkgsrc?
