Apple Mail on iPhones is currently ignoring autodiscovery and forcing their own
smtp server, breaking DMARC.

That is why these fuckers of Apple and Microsoft are doing it, and these morons 
at EU market abuse commissions don't get it, don't read complaints. etc. Also 
autodiscovery for external (as in, not Microsoft/Apple) mail is being 
frustrated. It is either on purpose frustrating or they have incompetent 
designers/developers.

Dovecot is, if you use LAYOUT=index. This will use only mailbox GUID on disk, 
and the folder name is only in indexes (both list index and mailbox index for 
recovery purposes).

I would recommend using 2.3.21 with LAYOUT=index to avoid problems.

I keep finding myself in a corner with a user. He uses mail

extensively, which

is fine, he has a huge archive of own professional correspondence,

which is

fine, but he uses mail folders as if they were regular system folders,

with

very long paths, and keeps renaming them and moving them around, daily,
breaking the mail index





Hi Rupert,

I share your frustration. I have had similar users, who used mailbox as 
a sort of task/ticket manager.  Each task was a separate folder, (with 
all related emails), and they renamed/moved the folder when the task 
status has changed.


It was OK as long as they used POP3 + Outlook and everything was in 
local PST folder. Until the PST grew over some limit (4 GB or such) that 
outlook was not able to handle.


So we migrated them to IMAP (cyrus), and ran into a problem with 
forbidden characters in folder names. Most prominent was "." - used for 
date format. But they kept on trying other special chars, always hitting 
something forbidden. (too late I realized I should have switched the 
folder separator from . to / before moving from POP3 to IMAP)


To make things worse, Outlook did not complain about forbidden 
characters, it just made folder "local only" and stopped syncing it to 
the IMAP server. Users gladly edited the folder name and removed the 
"local only" from the name so it was impossible to trace back which 
folders were synced and which not.


It was a constant pain ... Finally resolved by migrating them to MS-365.
Maybe dovecot would be more forgiving, but we did not dare to try.

I am offering users auto archiving of inbox and sent messages folders, both 
will be combined into a folder 2024 etc. Most users even appreciate this.

A bit weird is the moving of folders, most people have some logics behind it, 
and stay with it. Maybe he is using some shitty client on the phone? You have 
no idea what kind of crap 'rookie I only care about how it looks' developers 
can produce. I can remember trying to offer assitance to developers of such 
app. My user was using their app, and it generated like 800% more load than the 
average user constantly(can't remember exactly).

I don't get why you care? I am little surprised to read that this could be an 
issue. Is this maybe related to how you store messages? I am using this mdbox. 
I think nothing much changes there if they create/move folders etc. I have 
everything in 4mb files.

I have users that are doing the same, and offline clients are very capable of 
searching and retrieving messages. Never heard anything about this being a 
problem.

What about switching this user to different storage? I think that is doable and 
not that much work for one user. I am really surprised about reading this, 
since I have never experienced anything like this. I can't really believe I 
have been so clueless for decades ;) Can this really be an issue?
