I used to use Thunderbird Portable for my email. It was nice, but not every computer I interacted with allowed me to load even a portable app. Additionally, some companies block services like gmail. Having a self-hosted web-based email client is a godsend. I can check ALL of my emails (and I have far too many) from a single client. Review collected by and hosted on G2.com.

There were some issues during the original install, but once I got through them the software is flawless. I do wish there was a way to do a unified inbox. Switching between accounts can get tedious. Review collected by and hosted on G2.com.
