webmail in IscCP Omega only allowing 2 meg attachments

[NsOmNiAc]

Is there a file that needs to be updated to reflect 10 meg file attachments for outgoing mail using webmail instead of the default 2 megs already setup for ispcp Omega? This is also referring to the webmail not standard email. I just want all users to be able to attach over 2 megs if not 15 megs.I'm still combing the forums to find another way but any feedback would be appreciated. I don't believe it's a postfix configuration files that needs to be if so correct me.
Thanks in advance!
