hi,
we have cs mailscanner thing running on our server but when ever a form is sent by email to our customers for feedback its getting renamed.
check the form code below.
This is most likely the content scanning which checks for dangerous html (which includes forms in html emails) and disables them. To disable this checking, look in MailScanner.conf (via the WHM front-end if you have it) for "Allow Form Tags =". Set the value of this to yes if you want to allow form tags.
