IMAP (SSL)

Inbound (Secure IMAP):

secure.emailsrvr.com (Port 993)

Outbound (Secure SMTP):

secure.emailsrvr.com (Ports 465 or 587)

We strongly advise against setting up mailboxes as POP, as it is an outdated protocol. POP also does not sync emails back to the server (read/unread states, sent emails, deleted emails) and also deletes emails on the server after 14 days, if configured incorrectly. So if your hard drive crashes, we don't have a copy of the emails on the server; as the only copy is stored locally on your computer. 

POP (SSL & Non-SSL)

Inbound (SSL POP):

secure.emailsrvr.com (Port 995)

Inbound (Non-SSL POP):

pop.emailsrvr.com (Port 110)

Outbound (SSL SMTP):

secure.emailsrvr.com (Ports 465 or 587)

Outbound (Non-SSL SMTP):

smtp.emailsrvr.com (Ports 25, 587, 8025, 2525)
*For non-SSL SMTP, you can use any of the ports listed. Some networks block port 25, which is why we provide the alternate ports.
