When I 'telnet localhost 25' i get: email# telnet localhost 25 Trying ::1... Connected to localhost.xxxxxxxxx.com. Escape character is '^]'. 220 email.xxxxxxxxx.com ESMTP Sendmail 8.13.8/8.13.8; Mon, 12 May 2008 10:0= 1:39 -0400 (EDT) But if I try the same thing from 'outside' the firewall I get: %telnet email.xxxxxxxxxxxx.com 25 Trying 67.x.x.x... Connected to email.xxxxxxxxxxx.com. Escape character is '^]'. Connection closed by foreign host. Certain servers are having problems sending to the server because they are = not getting a 220 code back. Most email is sent/received from the server n= o problem. It has been running in production for over a year. Any ideas?
