iCloud IMAP Error

Reported by Des Dougan | March 19th, 2021 @ 04:05 PM

I started receiving pop-ups from MailMate this morning:

MailMate encountered the following error: “Server response: “C3 BAD Partition pending requests queue is full: partitionMaxPending=128 (took 2309 ms)”.”.
Mailbox: “Junk”.

I tried Retry and it went away for a bit, then came back multiple times. I closed and reopened MM and am seeing them still. I've not yet rebooted my laptop.

Version 1.13.2 (5673)

Thanks, Benny.

    Rebooting won't help. This appears to be a server issue. For now, you can try taking the Junk mailbox of the account offline, e.g., for 24 hours. Then take it online to see if the issue has gone away.

    (I have no idea what the iCloud IMAP error message means and I've never seen it before. It seems to be rare since googling for it didn't reveal anything.)

    After I told it not to retry, the message has not reappeared.

    Thanks for getting back to me, Benny.

    Make sure the Junk mailbox in the account is back online. Find it under Sources in the mailbox list.

    In case it is helpful I have started to get a similar message today:

    MailMate encountered the following error: “Server response: “D3 BAD Partition pending requests queue is full: partitionMaxPending=128 (took 3228 ms)”.”.
    Mailbox: “Junk”.

    Retry just brings it back moments later. Oddly, I got a similar error for another mailbox earlier and Retry made it go away.

    Server response: “D3 BAD Partition pending requests queue is full: partitionMaxPending=128 (took 711 ms)”.”.

    Got the same error as Mark today.
    In my case MailMate seemed to have been locked up and one of buttons on the dialog were clickable (grayed out).
    Even stranger after I force quit MailMate, the dialog is still on my scree.
    When I opened MailMate back up it was not responding for about 2 minutes, then it came back up...

    This still seems to me to be a server issue, but I've had several reports about it recently. @Jon: Maybe MailMate isn't handling this error as gracefully as it should. Could you generate logs for me like this if possible:

    • Open the “Activity Viewer” in MailMate (Window menu). This enables logging.
    • Observe a few rounds of this error.
    • Use “Help > Send Server Logs”.

    Then I'll see if MailMate could be part of the problem.

    Is this an ongoing problem for others? I just got the same message: "D3 BAD Partition pending requests queue is full: partitionMaxPending=128 (took 4 ms). Mailbox: INBOX" Any suggestions?

    I just now got the same error message (for all mailboxes on my iCloud account: Inbox, Junk, Deleted Messages, ...).

    My primary advice is still the same. Take the account offline and retry later.

    Maybe also check your IMAP account settings. Make sure you are using imap.mail.me.com/smtp.mail.me.com. If settings were imported from Apple Mail in the past then they might be different. This could be a problem if it forces MailMate to connect to specific iCloud server instances and those instances have the issue you are experiencing. (I don't really know how iCloud works server-side. This is just a wild guess.)

    In my settings there were more specific addresses indeed. I changed it to the more general form as you suggested. The error message hasn't popped up since.
