Unexpected Banner
« on: May 23, 2017, 04:29:42 PM »

On the enthusiast level test, upon sending my mail to my postfix configured email server, I'm given the error "Unexpected banner:". Any idea what this could be?

Banner probably refers to the first line of text that the SMTP server outputs.  It should probably look like:
Code: [Select]
220 [i]hostname[/i] ESMTP [i]packagename[/i]There might legitimately be several lines all but the last start with "220-".  If, when you connect to port 25, you see anything other than these, then that is probably the problem.  Typically, test this with something like "telnet -6 hostname 25"
