Hi!
I switched to using mbsync about a year ago, because I wanted to use something that would let me also sync downloaded mail between my devices directly, but since mbsync uses IMAP, old mail no longer gets deleted.
I tried to manually delete old messages via the web interface, but unlike in GMail, select all does not actually select everything returned by the filter.
I don't have time right now to figure out a patch to mbsync to do this and would appreciate some help.
I'd also be fine with an admin just deleting everything older than a month. I did a full sync to two machines today and have backed them up to my usual backup service. I still have about 20% of space, so this is not urgent, but I'd like to figure it out before my inbox fills up.
ps.: Thank you so much for your work <3
I'm sorry, we don't have the ability to access or maintain your mailbox in the way you suggest. You can manually delete 50 messages at a time through the webmail interface.
