Unify IMAP folder usage between webmail clients and popular desktop clients

Nuno pereira shared this idea 8 years ago
Completed

Hi all, i have a problem in Imap, when outlook syncronize with server, creates the folders inside the Recive and not each one like normal pop, so i have a tree with 1º Recive and iside recive 3 folders, send, trash, spam, this happened also in Apple, Iphones Ipads, this is wrong because the send email in outlook don´t appear inside the send but outlook creates a send folder, with 3 accounts on outlook this is impossible to have Imap with send emails on each account.

On roundcube they are all seperated folders, but on syncronize this gets ugly

This is now available in 11.48+

It is extremely unlikely that this feature request can be fulfilled. Each mail client seems to have its own preference on what they feel is the proper/desired IMAP structure for the basic Sent, Draft, and Trash folders.


While Outlook may utilize "Sent", Apple's Mail client uses "Sent Messages". This is a similar concept amongst the webmail clients. There is effectively no realistic way for us to unify all of the clients (most notably the desktop clients like Outlook, Thunderbird, etc) so that they all utilize the same default mail folders.


However, each mail client (including the webmail clients distributed with cPanel & WHM) have functionality to customize what folder is used for each behavior. The recommended solution is therefore to configure your mail clients to all use the same mail folders. This will alleviate the problem for that account.


This has been assigned case 121329 for internal tracking.

We could define a preset of folders and names. Just to prevent that every client created its own common folders again.


Once there was the IMAP "XLIST" command to communicate the folder names to the IMAP clients. If I am right, this XLIST extension should no longer be used.

Instead we got the "IMAP LIST Extension for Special-Use Mailboxes":

http://tools.ietf.org/html/rfc6154


Quote: "This extension adds new

optional mailbox attributes that a server may include in IMAP LIST

command responses to identify special-use mailboxes to the client,

easing configuration.


In addition, this extension adds an optional parameter on the IMAP

CREATE command, allowing a client to assign a special use to a

mailbox when it is created. Servers may choose to support this part

of the extension, but are not required to."


Dovecot 2.1 or above supports that.


namespace inbox {

#mailbox name {

# special_use = \Drafts \Junk \Sent \Trash \Archive

#}

mailbox Drafts {

special_use = \Drafts

auto=subscribe

}

mailbox Junk {

special_use = \Junk

auto=subscribe

}

mailbox Trash {

special_use = \Trash

auto=subscribe

}

mailbox Sent {

special_use = \Sent

auto=subscribe

}

mailbox "Sent Messages" {

special_use = \Sent

}

mailbox Archive {

special_use = \Archive

auto=no

}

mailbox "Archives" {

special_use = \Archive

auto=subscribe

}

}

Another way to unify folders would be the use of MailboxAlias


http://wiki2.dovecot.org/Plugins/MailboxAlias


Quote: This plugin can be used to configure mailbox aliases, which on the

filesystem level are symlinks to other mailboxes. This doesn't magically

solve the problem of showing clients e.g. multiple Sent mailboxes, but

it can be used to make sure that all of the different variants will have

the same mails in them. Unfortunately it also means that some clients

will download the same mails to local cache multiple times.

They seem to implement the preconfigured foldernames. The internal case number is also mentioned here

The follow directives will be added to dovecot.conf on the next update (please ignore the line numbers):


Note that they are slightly different then the ones being requested as these worked best with our testing.


  1. 311 mailbox Drafts {
  2. 312 special_use = \Drafts
  3. 313 auto = subscribe
  4. 314 }
  5. 315
  6. 316 mailbox Junk {
  7. 317 special_use = \Junk
  8. 318 auto = create
  9. 319 }
  10. 320
  11. 321 mailbox Trash {
  12. 322 special_use = \Trash
  13. 323 auto = subscribe
  14. 324 }
  15. 325
  16. 326 mailbox Sent {
  17. 327 special_use = \Sent
  18. 328 auto = subscribe
  19. 329 }
  20. 330
  21. 331 mailbox "Sent Messages" {
  22. 332 special_use = \Sent
  23. 333 auto = no
  24. 334 }
  25. 335
  26. 336 mailbox Archive {
  27. 337 special_use = \Archive
  28. 338 auto = create
  29. 339 }
  30. 340
  31. 341 mailbox "Archives" {
  32. 342 special_use = \Archive
  33. 343 auto = no
  34. 344 }

Will this cause any issues for users who currently have e-mails configured in their software ?


Apart from this, sounds good ! :)

So far we haven't had seen any issues, and I haven't heard any complaints from my co-workers since we made if live on our mail server.

This was poorly implemented. The solution above just creates more folders and helps email clients to find them. We don't need more repeated folders, we need alias. "Send Messages" "Sent Items" should be aliased to "Sent".


This can be easily archived with the mailbox_alias archived that just creates symlinks on the filesystem level to provide one directory with more than one name.


Here is an example with the Sent folder, and more info: http://wiki2.dovecot.org/Plugins/MailboxAlias


WHM team did it wrong, this should be reversed and replaced by the alias solution that is what everyone addend needs...


Thank you.

Hello,


The current implementation doesn't work well with Outlook. We often have customers who come to us from Exchange alternatives that are compatible with Outlook folders.


Before case #121329 was implemented you had to manually assign folders but at least is worked, now since this case has been implemented when a user assigns folders to have the default Outlook names he is unable to delete folders like sent, trash, drafts and also unable to unsubscribe to them.


For non english speaking users this is a real problem and cusomers don't understand why it works with their previous supplier but not with cPanel.


As TCB13 says, MailboxAlias sounds like it could fix this issue please look into it.


Currently cPanel's IMAP isn't usable for non english speaking users and for english speaking users that want to have the Outlook Sent items icon on their sent folder. Please look into this issue as not being compatible with Outlook's imap folders is a big issue with corporate customers.
