IMAP Client Configuration

Specific client configurations can be found in the list on the right.

Both incoming and outgoing servers must be set to use an encrypted connection.

If your client is not listed, use the settings below:

Name: Your Full Name

User ID or Account:  Your RCSID

Incoming mail server:

IMAP: port 143 with STARTTLS (preferred) or port 993 with SSL/TLS

POP3: port 110 with STARTTLS (preferred) or port 995 with SSL/TLS

Outgoing mail server:

SMTP: port 587 with STARTTLS (preferred), or port 465 with SSL/TLS

Outgoing server requires authentication: use port 587 with STARTTLS for encryption (sometimes called TLS or SSL for historic reasons, or "encryption"). This is preferred, but if that does not work use port 465, which is an SSL/TLS encrypted connection.
