IMAP hangs up

[rdclan]

Hello,

I use IMAP Server on my OXE 6.0 (Same CPU).

Got some Users with Outlook that check a common Mailbox with Outlook.

Every 1-2 Days, Outlook looses many times a Day the Connection and wants the Password for IMAP, and new messages only come in after refresh.

After booting the OXE, it works fine a few Days, than the same problem appears.

Any Idea ?

How can i restart the IMAP Service manually without booting the whole OXE ?

Thx.

Before you reboot the IMAP, did you try to debug it while customer says that it's frozen ? Did you try with another client than outlook ?

Hi Frank,

im not really good in IMAP and its Functions

Maybe i´ll try to learn to Debug IMAP (via Telnet and some Commands i Think) and post again, when it hangs up.

The Customer uses Outlook, got no other Software Running there.

.. new messages only come in after refresh.

About this: always new message will came after refresh.

Try using Thunderbird as a IMAP client.
I never use IMAP from OXE but I am using one for my company mail server. Try looking at some logs, perhaps /var/log/mail.log or something like this.

who knows witch IMAP server is using OXE?

What version of Outlook are you using? is it Express or Microsoft Outlook?
I saw that when using Microsoft Outlook 2003 but using Express worked fine.
Is your IMAP client configured to retrieve emails after X time automatically? On MOutlook 2003 it's not enabled by default.

Here is an example on how to debug:

telnet imap_server 143
1 login mailbox_number mailbox_password
1 select inbox
1 idle


Once a new message is received, you will see the screen getting an update.

EX:
(1)lab-a> telnet localhost 143
Trying 192.168.1.201...
Connected to lab-a.
Escape character is '^]'.
* OK [CAPABILITY IMAP4REV1 AUTH=LOGIN AUTH=PLAIN] lab-a IMAP4rev1 at Wed, 7 Mar 2007 22:02:56 -0500 (EST)
1 login 1000 1000
1 OK [CAPABILITY IMAP4REV1 IDLE NAMESPACE MAILBOX-REFERRALS SCAN] User 1000 authenticated
1 select inbox
* 13 EXISTS
* 0 RECENT
* OK [UIDVALIDITY 1170894635] UID validity status
* OK [UIDNEXT 63] Predicted next UID
* FLAGS (\Answered \Flagged \Deleted \Draft \Seen)
* OK [PERMANENTFLAGS (\Deleted \Seen)] Permanent flags
* OK [READ-WRITE] Mailbox status
1 OK [READ-WRITE] SELECT completed
1 idle
+ Waiting for DONE

You can see that when I do the 1 select inbox it says that I have 13 messages already.

If this works, then go and change your client

Hi Cavagnaro,

its Outlook 2003.
Yes, we configured the automatic Update.

By that way, i personally use Outlook 2002, and if the VoiceMail Folder ist open, new messages will appear on my Folder immediatly.

Hi Frank,

thanks for your Debug Tips, it drives my crazy

The 1 in front of the commands, i didn´t find yet....

Thanks !

Thx.

1) Look for process number using: ps -aux | grep imapd
2) kill <process number>
3) dhs3_init -R IMAPD

Notes:
1) you must log-in as root
2) test first in lab.
