Possible to increase connection limit for one user only?

I run a medium-sized virtual domain email server for about 15 domains. I also use it myself and have 3 or 4 devices using imap. I am often using a VPN to connect to my home network, which makes all my connections appear to come from one IP.

I want to increase mail_max_userip_connections just for myself only so I'm not opening up my server to abuse. Is this possible?
