Sounds like one of those "security" plugins for your web server, perhaps
mod_security.

It's set in an overprotective mode that freaks out and denies access
when it sees bits of text coming through the form submission that it
thinks are indicative of an SQL or code injection attack.

Contact your system administrator and let them know they've
misconfigured the software and should back it out to more reasonable
settings.
