Kickassd supports IMAP, POP3, and of course SMTP. Connections can be made VIA TLS, SSL, STARTTLS, or plain (though of course unencrypted is not reccomended) TLS is recommended.
Kickassd E-mail Ports
SMTP: Ports 25 / 26 / 587 SMTP SSL/TLS: Port 465
IMAP: Port 143 IMAP SSL/TLS: Port 993
POP3: Port 110 POP3 SSL/TLS: Port 995
When connecting with encryption use regular password not encrypted password as it is not supported and it is not needed. If you are connecting with SSL/TLS than the information is already encrypted.
Note: Additional information can be seen in your e-mail accounts page within cPanel. On any e-mail address click on "Configure Mail Client".
Encryption On Standard Ports It is possible to connect on standard non-ssl ports with encryption if preferred. Standard ports being 25, 26, 587, 143, and 110. In your E-mail client choose STARTTLS as encryption type, this is basically a "connection upgrade". It starts as a plain unencrypted connection and becomes encrypted.
