Check for string on web site failing

Folks

I set up a check to match a string for a web email server in my bb-hosts file to ensure that the page was loading properly. The check looked like:

10.10.5.173 foobar.pnl.gov # class:server cont=WebMail;https://foobar.pnl.gov;WebMail.Access

The check worked fine until this past weekend when the email server was migrated from Exchange 2003 to Exchange 2007. Now instead of an index.html file being downloaded, I get a SGML document. Even though the same string is in the title tag in the document, the check fails. Can someone suggest a way to check that the page has properly loaded?

Thanks for your help.

Regards,

Cathy
