Is there a way to get Gmail to notify me when it is unable to retrieve mail from my other accounts?
I have Gmail checking several accounts (under Settings → Accounts & Import), but on occasion it fails to connect to a web server (usually because that server is down).
If I go into Settings → Accounts & Import there is a red warning message that it failed, but I may not notice this for hours or days.
Is there any way to get some kind of warning on the main page of Gmail? It could be a message box or an email.
