The directory in the subject line grows constantly over days when protonmail-bridge is used on Arch linux along with neomutt as the email client.

Expected Behavior

I believe this directory is where protonmail-bridge stores a local copy of emails. It should only grow as much as the remote inbox grows, not disproportionately.

Current Behavior

I have reset protonmail-bridge at least three times now, both using the GUI and the CLI by deleting and re-adding my account. Every time I do this, the directory in question goes back down to 1.1 GB in size, but regrows to several GBs within days. Once it reached to 9.5 GB size. I reset the bridge today again since 5 days from the last reset, and the directory was about 7 GBs in size before the reset.

Possible Solution

I am using mbsync (part of isync package in linux) to sync my local inbox sync with my protonmail inbox through protonmail-bridge. Optimize protonmail-bridge to work in harmony with mbsync.

Hey @hakova do you keep bridge running forever as a service or do does it shutdown and restart with your user sessions?

[LBeernaertProton]

Were you also prompted to resync or got logged out in the past?

@hakova do you still have issues on the latest version of bridge?

[gbrener]

I am experiencing the same issue, and the protonmail bridge desktop app says it is on the latest (non-beta) version. To answer the questions above: I typically keep the bridge running as a service, and it does not shutdown/restart unless I reboot. I was not prompted to resync in the past.
