From field not configuring properly

Hello, I have the from field on several of the websites I administer as:

[your-name] <[your-email]>

This has worked fine on several other websites; it sends the email to me, from the person who filled out the form, and I’m able to reply to them seamlessly.

However, I have one site where instead of putting the proper email address (say [email protected]), it’s changing it to [email protected] … if that makes sense? I’m not sure what I need to change to make this format properly, as I indicated, I’ve never had problems with this formatting before.

Any advice would be greatly appreciated.
