ethos Posted August 5, 2008 Share Posted August 5, 2008 Hi guys,I have a problem with SMTP on a 2003 server. It's running as I get;220 xxxx ESMTP ready at Tue, 05 Aug 2008 11:04:36 +0100When I try and telnet into it, I can send emails via outlook express but not via command prompt (telnet) or any programs (backup exec for example).Any ideas?I get 501 Syntax error when trying to mail from: Thanks.

eyeball Posted August 5, 2008 Share Posted August 5, 2008 (edited) so if you telnet to ip on port 25 what happens when you type the mail from: command? what happens on rcpt to:? (if it gets that far?)have you tried internal telnet as well as external?Also is the box running exchange?, if so do you have your domain listed in the recipient policy?Thanks Edited August 5, 2008 by eyeball Link to comment Share on other sites More sharing options...

When I telnet I get this far;220 server ESMTP ready at Tue, 05 Aug 2008 12:11:58 +0100helo 192.168.1.4250 server Hello Unknown, ready to receive from - 192.168.1.4mail from: xxx@xxx.com501 Address Syntax Error in xxx@xxx.comThis is an exchange server yes, I can't seem to find ANYTHING on the server tho that would indicate me to how/what this is setup with.I only have "(mailnickname=*)" in my receipt policies....I'm sure this is all very simply stuff but I've never really played with SMTP and have some into a network with no documentation at all.

eyeball Posted August 5, 2008 Share Posted August 5, 2008 (edited) what if you just type "helo" instead of helo 192.168.1.4?surely its failing because you are saying i am domain"192.168.1.4" but thats not where the mail from: command is showing Edited August 5, 2008 by eyeball Link to comment Share on other sites More sharing options...

Put port 26 in and everything is good now!!!!Argh! Link to comment Share on other sites More sharing options...
