When I forward few html emails, I get the above error.

I have even deactivated the mod security for the client account.

Please help fixing this.

Mod_security is used for a very good reason: WAF! Disable at your own peril.
Actually read the error message; it does help.
Just use the GUI to disable the rule identified by  [id "949110"]  - easy.
