Outgoing server (on and off campus)
How To, IMAP/POP3 setup, SMTP
A SMTP server, outgoing.downstate.edu can be used as the outgoing server (SMTP) on port 587 and 465 (SSL) on and off campus for Downstate email. The default port 25 is not allowed. We recommend port 465 for better security.
Accessing third party SMTP servers for internet email accounts from inside of campus is only allowed on port 587 and 465(SSL), which are supported but most service providers. If in doubt, please contact your ISP.
