Mailbox is locked by POP server

Syd,

this is not due to 10.5.5, but would happen with any Cyrus setup. Only one client can connect to a POP account at a time. If your desktop mail client and iPhone client connect at the same time one of them will be locked out. Best to use IMAP for the iPhone (you can keep using POP on your Desktop).

HTH,

If you are absolutely sure that users with a single mail client experience this issue as well, I recommend you check your network. Network dropouts could cause this behaviour as well.

To use IMAP instead of POP, just select it when setting up an account on the iPhone.

I have the same exact problem, yesterday I upgrade the server to 10.5.5 and today the server is rejecting the conections.
I found this:
- All incoming messages are not redirected to the mailbox.
- When the pop user connect to the mailbox, they recivied all the messages stored in the mail box, but the message are not deleted from the mailbox, so when the users gain access to the mailbox again the recived the massage all over again.
- Nobody can access to the Webmail, nor the pop or the Imap users.

I tried to restart de server and recosntruct the mailbox from the Server Admin but no joy.
so I found this article i follow the instructions to reconsctuct the mailboxes and it worked. but with one stepback: When the Imap users or the Pop users that store the messages on the server al the messages they stored are downloaded again. But you can override this stepback by access the webmail user and mark the messages "read"
