    I have this same issue. I was assuming it was because iCloud doesn't support tags (right?) but I see I'd previously succeeded in adding tags to some messages so now I'm not so sure.

    I am using Version 1.14 (5820).

    Yes, I too have some iCloud emails that are tagged with MailMate but most times it balks at the process. It's inconsistent. Sometimes it won't allow any tags. Sometimes just one. Othertimes, it will allow one or two tags but then if I add another it will hold the tag there for 5 seconds and then delete it BUT it still holds the first or two tags. I can't see any rhyme or reason to the process. I've even deleted the tags I have installed in MailMate and then rebuilt with new tags -- nope, didn't change the problem.

    I have witness this "disappearing tag" behavior before on other servers but didn't have the time to run it down. It didn't occur to me to pay attention to which accounts it happened to. Certainly either gmail or outlook, possibly both. Generally if I just add the same tag again that fixes it, though, whereas on iCloud I get these errors. I suspect there is more than 1 issue.

    We can at least investigate what happens with the BAD error. At least to see if MailMate is to blame. I'd prefer if this was done with the latest test release of MailMate which is currently this one: r5831.

    Do as follows:

    • Open the Activity Viewer (see the Window menu).
    • Relaunch MailMate (this is to make sure I also get the logs of MailMate connecting to the mailbox).
    • Trigger the error message at least once.
    • Use “Help > Send Server Logs”.

    Then I'll see if MailMate does anything wrong when setting the tag.

    In general, not all IMAP servers work well with IMAP keywords and they some times have some kind of limit on the maximum number of IMAP keywords to be used (but MailMate has no way of knowing this number). Gmail should work fine though as far as I know.

    Benny, I updated to r5831. Went through the steps you asked and sent the log in ( with part of this conversation added so you had context ). In short, the new version (r5831) is not throwing up the iMap error message mentioned before BUT the tags still keep disappearing on iCloud messages. I realize this could be a statement on how iCloud IMAP is set up, but, it's a feature (tagging icloud messages through MailMate) that has worked for me for a long time until now. Will be curious.
    Thanks for your time.

    Here's example output from Kerry. The first line tells me that the server does allow custom flags (that's the meaning of \*). The next lines show that MailMate attempts to enable test. Because of buggy servers MailMate also checks if the action really worked and this actually fails. The end result is that MailMate disables the flag locally. It could work differently, but it doesn't change the fact that the server seems to be the problem.

    Here's example output from Daniel:

    19:02:29 Storing flags (enable: 'ComputerStuff/Apple', disable: '')
    19:02:29 C: H8 UID STORE 4 +FLAGS.SILENT (ComputerStuff/Apple)
    19:02:29 S: H8 BAD Parse Error (took 0 ms)
    19:02:29 Error: Server response: “H8 BAD Parse Error (took 0 ms)”.

    This is a different issue most likely related to the use of / in the IMAP keyword. I've checked the standard and this character should, as far as I can see, be allowed in IMAP keywords which means that this is a server bug. Note that the Tag name in MailMate and the actual IMAP keyword do not have to be the same. You can change the mapping in the Tags preferences pane of MailMate.
