I'm very new to linux so please assume I know nothing about linux. Have installed debian onto a server and vhcs and using that for the mail, opened ports for smtp and pop3 to the server as I want to use it as a mail server for my domain, lets call it mydomain.com
Three mailboxes all with mail sitting in them
currently at an ISP on pop server pop.mydomain.com
Have created the same email accounts in vhcs
Now I know I could download all email to an email client such as thunderbird but user2 and user3 have always used webmail and want to stay with webmail.
How can I, or what software would I use to grab all the email from the current pop mailboxes and transfer them to the new pop mailboxes before I move the domains MX records to the new server? I guess I'm looking for something similar to EFS, but this is a MS Windows only program it seems.
I hope this is clear
