GNOME Bugzilla – Bug 766463
Delay in showing new messages in inbox for Yahoo accounts
Last modified: 2016-12-20 13:53:21 UTC
Accounts created as Yahoo! Mail accounts are slow to show new mail appearing after it has been delivered to the Inbox and already visible from the Web UI. It doesn't seem related to the number of accounts or whether the Y! web interface is open - during testing it occurred when it was both the second and first (only) account, with both the web interface open and closed.
Maybe related to Bug 748548?
That's for davmail servers. Looks more like Bug 755147 instead. *** This bug has been marked as a duplicate of bug 755147 ***
