Package: postfix-mta-sts-resolver
Version: 1.1.2-1

The default for this package is to use a cache type of “sqlite”. Due to an issue with the python3-aiosqlite library (addressed in this unmerged PR: https://github.com/omnilib/aiosqlite/pull/213), this daemon is constantly using at least 1% CPU, while doing nothing.

Until the aiosqlite issue is addressed, I recommend changing the default cache type to “internal”, which does not have this issue. It’s a very sane default, and sites requiring a larger cache can switch cache types.

This is as tested on Ubuntu. Apologies for posting here, but I felt it was important to be addressed as upstream as possible.
