WeOnlyDo! Mail Server is a set of components to create standalone full mail server system on your network. It contains our Pop3Server, ImapServer, SmtpServer and Mailbox LITE components.
Combined all four together, they make a powerful package that can be used to receive incoming mail from outer networks, usually Internet, to provide Pop3 and Imap mailboxes to your employees.
Using strength of Mailbox component, you can access complete users` mailboxes at once. Just open user`s mailbox, get information about messages, delete them, add new ones, create messages on the fly, etc..

Imagine what you could do with MailServer components:

you can deny spam email to be forwarded to users` mailboxes
you can create messages on the fly for each user
you can add messages to their mailboxes as needed
you can change information in their mailboxes, unzip files for them...
you can publish attached files directly to your public folder
you can automatically, as new email arrives, open it on your screen - just the way you want it
you can send messages to your coworkers just by writing to their mailboxes - and do it professionally
you can extract messages directly from your mailbox and open it in your favorite mail client...

Can you think of more? Sure you can. You will find a place for this package, depending on your needs.
All four components (Pop3Server, SmtpServer, ImapServer and Mailbox) are same as in separate packages.
