Need a Pop3 server...
I rent a Linux server for my web hosting company and it came with an IMAP e-mail server but IMAP sucks and i need to replace by what i've always used... Pop3 servers.
Can anyone recommand me something ?
OpenSource is fine but it needs to be something serious...
Ideally, something that my customer will be able to use to create new e-mail accounts.
The apps that are commonly used for pop3 are dovecot and courier. Look into those two and I am sure one of them will meet your needs.
