Horde/MailEnable problem

[mysticBoer]

I have a server running Windows 2003.
Mail Server : MailEnable
Webmail Client : Horde 4.0.1

When I go to webmail.mydomain.com (which worked fine up and till 2 weeks ago) I get the following error :

Content Encoding Error (content_encoding_error)


Server response could not be decoded using encoding type returned by server.
This is typically caused by a Web Site presenting a content encoding header of one type, and then encoding the data differently.

For assistance, contact your network support team.

I am unable to get to my login screen at all.

If I log on to my server remotely(Remote Desktop), and type in webmail.mydomain.com the Horde email client opens up like it usually does, with no errors at all?

Any suggestions? This is very urgent...

OK, I suppose this is a new one to you guys as well. What I can add is this :

This morning I did a virus scan using TrendMicro HouseCall. I found 2 instances of the same worm, worm.Stration. The system removed these two instances. I restarted the server, re-did the scan and found nothing. My webmail however remains unchanged.

Also, sometimes email get's stuck in the MailEnable queue. A user would be able to download up to 147kb and then it stalls/times out.

This has happened to multiple users...

It seems a bug in Horde content copmression code causes this.

You should set

$conf['compress_pages'] = false;

in webmail/horde/config/conf.php. This resolved our issue.
