Need IMAP solution recommendation
I'm running an acient system that I've used for the last 5 years but no longer really supported. It's the old Linuxconf virtual email system using a patch version of WU Imap. I've adapted Exim as my MTA which I love to be compatible with it. Linuxconf gives me an HTML interface to manage it all and it works.But now I wan to move up to something new, modern, strong, flexible, and I want to "do it right". I'm hosting about 200 virtual email domains on a FC4 box. Users use their entire email address for login.
The passwords are stored in separate files for each domain.
password.domain.com
shadow.domain.com
alias.domain.com
Password and shadow files are the same as the Linux password and shadow file format. Need to migrate these somehow.
I wish I were starting from scratch, but I'm not.
Any suggestions?
