Comment 18 for bug 865012

Mihail, thanks for the reply. Yes, it seems that hiding error icon after the first successful check would be sufficient.

But now I have realized that mailwatch plugin design imply that there is nothing as "check of all mailboxes" (all in the same time). Each mailbox has its own thread and is checked independently from others. Then we can say that error indication icon may be hidden after the last check from the sequence of successful checks of all mailboxes starting with the first mailbox. If I implement it like that, it would mean that if user has two mailboxes, one with checking interval 2 minutes and one with the 60 minute interval, in the worst case it will take almost 58 minutes (and 28 successful checks of 2-minute mailbox) until error icon disappears.

The better solution would be a "distributed" version of this mechanism. Error/warning should be cleared only by the next successful check of the mailbox which caused it. The error icon would be hidden only if there is no mailbox with error status and showed otherwise.
