Webmail/Remote Admin through ISA proxy

[sjoram]

Hi all,
Run AMS as a mail server at home.
When accessing webmail/remote admin via our ISA proxy at work, often it will refuse on the first few attempts to accept the correct username/password.
Occasionally get HTTP 400 Bad Request
As soon as I disable the ISA proxy, I can log in absolutely fine.
Any suggestions on what might be causing this?

Generally there should be no problem accessing WebMail via a proxy as many users do this without realising and have no issues. However, this could be indicating that there is a possible bug in the WebMail HTTP system and so I would be interesting to know the version number and product name of the proxy involved (if possible). In the meantime I have made a note for an engineer to investigate this before the next release.

Rob,
I'll try and find out, but I don't hold out much hope.... (sorry!)
If I can get any more detailed info, I'll let you know...

Rob,
I've been advised we are running ISA 2006 & Websense v6.3

I've noticed this on an increasing frequency with other sites that use any kind of login authenication.
A possible cause... http://support.microsoft.com/kb/941293/

If this is occuring with other websites then most likley this is indeed related to the particular proxy you are using. Unfortunatly we cannot recommend the best way to deal with this as it is somethign we haven't tried configuring ourselves, but the link does seem to indicate at a possible solution.
