Problem
Looking for a list of outgoing SMTP servers?
Solution
An outgoing SMTP mail server handles all outbound emails and delivers that email to its end destination (the incoming email server). ISPs (Internet Service Providers) and MSPs (Managed Service Providers) like us will publish their outgoing SMTP server information for their end-users.
We have complied a list of those servers below, but of course if there is one missing then please let us know. There is an add button at the bottom of the page.
Although this page is focused on outgoing SMTP server information, where available we have added the icoming (POP3 and IMAP) details as well.
outMail is an outgoing SMTP relay service also known as an SMTP SmartHost service.
Outgoing Server
| Server | Protocol | Port | Notes |
|---|---|---|---|
| mxXXXXX.smtp-engine.com | SMTP | 25 | Auth, StartTLS, SSL |
| SMTP | 465 | Auth, SSL | |
| SMTP | 587 | Auth, StartTLS, SSL | |
| SMTP | 2525 | Auth, StartTLS, SSL | |
| SMTP | 8025 | Auth, StartTLS, SSL |
Notes
Of course we would put outMail at the top of the list when its our service ;-)
outMail has published SPF records, and supports DKIM signing. outMail is an authenticated service offering SMTP on ports 25, 465, 587, 2525 & 8025.
mxXXXXX is an assigned server, so you need to refer to your welcome documentation for the exact information or look it up in the management portal.
