It would help tremendously to have a possibility to view mail accounts in a list view and sort them alphabetically. I have users, aliases, mailing lists.
Admittedly coming from postfix “virtual” file, it needs getting used to. But in the virtual file I could sort and group my mails and saw in a split-second if I already had the alias. It was also a lot easier to turn an alias into a “mailing list”. But mostly as it was easily readable. info, mail, hostmaster, postmaster, plus some aliases. Oops, did I add that one? Can’t find it in the stalwart database either.
So I now maintain a spreadsheet file for us to keep track of the accounts outside stalwart (in Nextcloud). It’s what we call a media disruption when I need Excel to manage native tasks? So yes, to improve usability, as a Feature Idea, please enable a easier interface look, with search and sortation. The current UI is focused on small installation IMHO.
