Persistent warning/notification when POP3 retrieval fails?

[Philip]

I retrieve my email for a number (12+) of accounts through AquaMail, all of them using POP3. I do not wish to use IMAP.

One of these accounts (with btinternet, which is basically a badged Yahoo! Mail service) has frequent bouts when POP3 fails. There are workarounds (logging in to their webmail service on my phone’s browser) which fixes things for a while, but my big problem is that I have no way of knowing that the polling/retrieval is failing, other than the absence of emails being retrieved for that account – and there’s no easy way to know that this is happening, unless there’s a particular email that I’m expecting 

Is there any setting in AquaMail which will provide a persistent warning/notification when POP3 retrieval fails for a given account? I’ve tried to look through all the available settings, but haven’t found anything.

Depends on how it fails exactly, could you clarify?

For network errors (server breaks connection, or data connection gets disconnected or dropped) - we do post a status bar notification if it happens "each time" over 12 hours or longer.

For login errors we put a red error message on the app's main window.

What sort of failures are we talking about, exactly? Can they be fixed on the server?

Thanks, Kostya.

The problems are all entirely at the btinternet/Yahoo! Mail end (there are numerous topics on the various support forums going back a number of years discussing this). There's nothing that can be done at the client end - other than the user logging in to the webmail interface through a web browser, which then allows POP3 to work for a period. This affect all clients (K-9 on Android, Outlook on Windows 10, etc).

The errors are usually User Authentication errors or Timeouts, but they do vary. Sods law, it's working OK at the moment, but next time it fails I'll try to capture the error.

If I knew that retrieval was failing, then I could apply the workaround, but my problem is that I don't seem to have any (persistent) error from AquaMail to warn me that polling that particular account is failing.

Hope this makes sense.

Login errors result in status bar notifications. Or they should I should say - unless you've turned off error notifications in app settings. Or there is a bug somewhere
