The POP, SMTP and IMAP Setting for email running on the Truska platform is as follows:
The Username is the FULL email address (i.e. firstname.lastname@example.org)
POP (Incoming) server: pop.truska.net
SMTP (Outgoing) server: smtp.truska.net
IMAP (Incoming) server: imap.truska.net
If asked it is an SSL connection
Default ports should work
But if not already set to the following you could try them
SMTP: 25 (or if having a problem abroad try 63325
To send from Outlook and other similar client you will need to authenticate the outgoing mail
In Outlook Account settings go to More or More Settings then the Outgoing Server Tab and click "Use same setting as my incoming mail server".
The exact wording etc will vary from client to client and version to version.
Username and password where issued when the account was set up.
