I can't login to all email account. I tried to test it trough telnet and it shows the following error:

"-ERR Unable to log on. Only one connection to a mailbox permitted at a time."

Hello ruelminds,

We never saw such error message. What is Mail server you are using?

I have upgrade my server to Plesk 8.3 Win and the POP3 problem is fixed. Seems Plesk 8.2 Win has many issue.

I'm having problem accessing the POP3 mail server.
I can't login to all email account. I tried to test it trough telnet and it shows the following error:

"-ERR Unable to log on. Only one connection to a mailbox permitted at a time."

This problem occurs when the user directory/postoffice folder does not exist.

You may want to verify that email is being delivered to the correct path first
using Plesk's Reconfigurer tool.

Once that's done, and if its correct..

Go into Mail Enable Administrator
Once the program is up, go into:
"MailEnable Management"
-Messaging Manager
-Post Offices
-Problem domain
-Mailboxes
-Double click on the problem mailbox...
It should prompt you to re-create the problem mailbox's
default mail store directory.

Then that mailbox should work correctly!

Problem solved (for us)

This solution solved this problem in our server:

1.- Modify the value of this registry key to 1:
[HKEY_LOCAL_MACHINE\SOFTWARE\Mail Enable\Mail Enable\Services\POP]
Concurrent Access Enabled= dword:00000001
2.- Restart POP server

That's all.
Problem resolved in our Plesk server.

We were also fucionado us the change log

We have a Parallel 9.2 and W2008. We made the change in value with Regedit and we restarted ... and it worked.


Simply, we had to do a little searching with regedit, because the key route was slightly different to the above cited

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mail Enable\ Mail Enable\Services\POP]
