Well I was against webbased solutions (and still against) but I've been writing my own software for a while so I'm totally confident on privacy and uptime issues (more than relying on third parties).
I'm now working from diff computers and devices, this pushes me into web based solutions. I'm also in need of collaborative replies and user assigned cases. I can't do that with pop3. Gmail sounds good, mail.com sounds better (away from gmail) ... Gmail is a service, mail . com is a service too so it doesn't hurt to mention both, both allow me to manage several email accounts. I just don't like G or privacy exposure.
I'm playing with code. Ticket system solutions are what I'm aiming for but none of them seems the right one by now. Thanks for the comments.
