Description david 2023-07-11 23:56:26 UTC 
I use https://doc.dovecot.org/configuration_manual/plugins/listescape_plugin/ to enable some special characters in mailbox names, and it converts `.` to `\2e`. After upgrading the Debian package for spamassassin from 3.4.6-1 to 4.0.0-6, I get the below error running sa-learn on Maildir folders with backslashes in them. Adding an additional backslash seems to help though:

Oops, I'm actually not sure this is related to the upgrade at all. I came across this bug while trying to figure out what was causing another bug. But I just realized that while debugging that one, I was running sa-learn in a different way than I usually do. (I usually change into the Maildir folder and run sa-learn with a path of `.`.) So I don't have any idea if this is a regression or not.
