In my app it’s possible to upload emails back into an IMAP account. This also creates the mailbox if the mailbox doesn’t exist. For one user the new mailbox doesn’t show up in Mail. My first idea was that the subscribe is missing. But the mailbox still doesn’t show up.
Does anyone have an idea what could cause the problem here? And yes, I know that it takes a while until the new mailbox shows up in Mail. We also did a “Synchronise all accounts”.
What mail service is this? If memory serves, once upon a time you could log into the Gmail web interface and selectively turn on/off which Gmail tags would be presented to IMAP clients. I used it to turn off the All Email tag to prevent downloading duplicate messages.
I wonder if it’s an opt-in situation where the user needs to check that box for newly created folders.
It’s not Gmail. The user has a domain with hosted emails. The question is a good one. But how would my software recognise such mailboxes? IMAP only supports subscribing to a mailbox.
In the case of Gmail, the Gmail IMAP service simply omits any tags that the user has deselected from the list of folders it reports to IMAP clients - so they have no way of knowing what’s not being shown.
Do you know what service this user is utilizing? Maybe that would help us understand.
Also - is this a problem with just this one user, or more widely spread?
