For those of you using AK email (Beast and Bojan), I have migrated it to a new server. Here are the changes:
Incoming: pop3.unicusconcepts.com (using the POP3 protocol, surprisingly enough)
Outgoing: smtp.unicusconcepts.com (requires SMTP authentication with the same credentials that you use for incoming)
You may use TLS for both incoming and outgoing.
Usernames and passwords are the same.
Webmail: https://roundcube.unicusconcepts.com (This is going to change to webmail.unicusconcepts.com once I've migrated all email accounts that I host.)
