Email Not Sending - Internet Mail Gateway Queue Not Moving

[bluecc]

Just noticed this morning that our outbound emails weren't going out. They leave all clients (Outlook, SWA, Evolution) just fine with no errors.

I then logged into SAC and noticed that the messages are stuck in the Internet Mail Gateway queue. It says "1 messages being processed" and just sits there. I manually deleted out the spam emails, stopped and restarted the service, and restarted scalix. I also restarted scalix-postgres.

Here's what I get from omstat -s

Any thoughts?

When running omscan -Aafx I get this error in the output::

Code: Select all

omscan : [OM 4951]
A serious error has occurred.  Please see the log files.
Event logged on 09.02.08 at 11:32:57.
Owner/Context Info : UNIX
Additional error info:
omscan : [OM 11170] Could not obtain exclusive access to a queue.


[bluecc]

Seems it's stuck on one message. Even after clearing the queue it shows the queue empty but still says "processing 1 messages, 1 message in queue" up top.

How do I find where that message is and manually delete it?

[schmoe90]

Stop the Internet Mail Gateway, kill any remaining unix.out processes, then look at things.

Hi I have the same issue. Running V 11.4.1

I have 10 msgs in the "internet mail gateway" queue that i am unable to remove/delete. I have tried deleting them via the SAC but this was this did not work.

I have stops all the scalix services

Code: Select all

omoff -s -d0

and restarted them

Code: Select all

omon -s

and have deleted the unix.out processes but the queue still sits at 10 msgs.

Code: Select all

omshowlog

shows no errors at all.

I can receive inbound emails but can not send them.

[Jaredf]

I have managed to remove the 10 emails in the queue, but now it just displays that i have 1 email processing.

I used

Code: Select all

omstat -q UNIX

to display the "msg ID's" in the queue and then

Code: Select all

omstat -q UNIX -j -R -m

to remove the emails one by one. See below.

Code: Select all

[root@icgmail03 ~]# omstat -q UNIX

Where does it display that you have a message processing? If there are no unix.out processes running, it's lying

[Jaredf]

Nice answer. "It’s lying"

When i look at SAC, it still shows that there is 1 email that is processing.

Is there a way that i can get the Message ID so that i can delete it?
I don’t want to recover it and don’t mind losing emails if need be.

I’ve also tried the

Code: Select all

omqdump -l UNIX

but this returned no results. Correct password was used.

Any ideas what i could do or is there a fault with Scalix 11.4.1, as i have the enterprise 11.3 running with 120 users without this issue since Nov 07. I'm only testing the new version to confirm that it works successful before upgrade from 11.3 to 11.4.1.

[Jaredf]

By stopping the UNIX "internet mail gateway" service and killing the unix.out processes, I can remove the email that is processing using omqdump tool. Then restart the UNIX service.

Basically every external email that i sent gets stuck in the UNIX queue. I am only able to receive emails and sent emails locally with the same domain.

Question:
Yes there any tests that i can perform to see why the email is getting stuck in the queue?

[Jaredf]

All Fixed

The problem was with Sendmail not scalix.

I updated the sendmail.mc (located in /etc/mail/) to only have:

Code: Select all

DAEMON_OPTIONS(`Port=smtp, Addr=127.0.0.1, Name=MTA, M=C')dnl

Ran make -d -C /etc/mail

Then restarted sendmail to make sure the settings worked.

The Problem:
I have previously entered the internal server IP address and the external internet IP for this server, so there was 3 lines all called MTA. Looking at the maillog i noticed that the sendmail was refused to send mail for the localhost 127.0.0.1.
