If you UNCHECK the incoming mail "requires SSL" flag, and CHECK the outgoing "requires SSL" flag, this will fix this issue.
Also make sure your email server is mail.<yourdomain> and NOT serverX.domainsunder.ca, so for example if your domain name is joesgarage.ca, then your mail server will be mail.joesgarage.ca
Outgoing port should always be 587.
Incoming port should be 143 for IMAP and 110 for POP type email.
Incoming username should be <name>+<yourdomain>, so if the email address is joe@joesgarage.com then the incoming username should be joe+joesgarage.com
Outgoing usernames are just the email address.
