vb.org Archive - View Single Post - SMTP settings give 550 Unexpected response from SMTP server during handshake.

Skyrider · #3 04-02-2020, 09:02 AM

I'm trying to connect to one of the MXRoute mail servers. (In this case, arrow.mxrouting.net). I wasn't aware that it was a server side issue, as I assumed SMTP connection goes directly through vBulletin. It's a Root server (mix between VPS and Dedicated), so ya.. I can adjust the mail settings on my server.

But even if I disable the "sendmail" which is installed on my server, still getting the same error. Postfix is not even installed.

Or this something within the server settings itself, or its mail application settings?

I'd like to point out that Xenforo has no issues sending out SMTP emails, vBulletin is the only one throwing out errors. So are you sure it's not vBulletin's fault?
