Webmail attachments fail-error logged on wrong server

[da]

We have come across a problem where one particular user cannot add attachments to emails being written in Scalix webmail (SWA). While a pop-up window opens at the normal size for adding attachments, that window contains an error (Error 500 from memory).

Here's the really curious bit...

We have two servers, one hosting Scalix (and backup software) and the other running providing various other functions including being the main DNS server for our network. The Scalix server (running Scalix 11.4.5.12163 on CENTOS 5.3) is named in the format ourmail.ourdomain.com and the DNS server (for historical reasons) is named mail.ourdomain.com.

When one particular user (and only this user) tries to add an attachment, an error is logged on the wrong server (i.e. on mail.ourdomain.com instead of ourmail.ourdomain.com. /var/log/httpd/access_log on that server records a line in the following format:

GET /webmail/jdownload?user=[USERNAME]&emailDomain=[DOMAINNAME]&guid=Ox66667c78796e60682b35343032272b2929232908&box=New_Inbox&uid=2692&mime=image%2Fjpeg&part=1.2&filename=__file__2692__1.2&__cid__=171470202@23102008-30A5 HTTP/1.1" 404 215 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; GTB6)

Any ideas?

Can you post the output (on the scalix server) of:

omshowmnmp
and
omshowu <username>

All I really care about is the mailnode for the user. You can delete everything else.

Is SWA running on the same server as Scalix Server? Or is SWA split off onto it's own front end server?

Also, is there anything in /var/opt/scalix/??/s/webmail/swa.properties that looks wrong? (points at the wrong server)?

Kev.

Thanks, Kev

In answer to your questions:

omshowmnmp:
ourmail ourmail.ourdomain.com
mail

omshowu <username>:
MailNode: ourmail

Yes, SWA is running on the same server as the Scalix Server.

There is nothing in /var/opt/scalix/??/webmail/swa.properties (not /var/opt/scalix/??/s/webmail/swa.properties) that obviously points at the wrong server. (I wasn't expecting there to be, as only one user has the reported problem.)

Thanks again for your help.

Check DNS for both affected servers on the client machine.

Do a ping, and make sure the IPs are correct, check the hosts file, etc.

Also, try (just for laughs) clearing the cache on the desktop's browser.

Kev,

I didn't mention in my earlier post that the same problem occurs for the user from different PCs (in office and at home).

I will try ping, hosts, cache on the office pc as you suggest when the user is next in.

For anyone who sees this thread in the future...

It looks like the /var/log/httpd/access_log entry quoted in my original posting was unrelated to the main problem. It was due to an outdated link to an image in the user's auto-signature.
