Suggestion: make mail filters exportable
Over time, quite a lot of work can go into setting up the mail filter rules that one uses to sort email. If one wants to make security backups or move the filtering away from the mail server (e.g. to the mail client), it would be beneficial to be able to export one's sieve scripts in the form a text file/multiple text files. It would also align with the open source principle that the user owns their own data and should be able to move it, not having it locked into one service.
I suggest such an option which allows the user export their sieve filters, either in bulk as one file, or as individual files for every rule.
Thank you for your consideration!
