[cobalt-users] MAIL/EXPN/VRFY/ETRN - Not localhost but all domains

["Gil Bechtel" <gil@xxxxxxxxxxxx>]

All set with this one......
Jul  4 08:45:06 ns1 sendmail[14991]: NOQUEUE: localhost [127.0.0.1] 
did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA


But the following log entries have me confused, anytime a customer 
goes to send mail from various ISP accounts they get the same error 
message from Outlook.

"Task 'theirdomain.com - Sending' reported error (0x8004210B) : 'The 
operation timed out waiting for a response from the sending (SMTP) 
server. If you continue to receive this message, contact your server 
administrator or Internet service provider (ISP).'"

And the mail log looks like this showing their attempts to send mail.

during connection to MTA

But if the customers use the web based email (neomail) that is on the 
server they can send mail.  So why is every customer that is trying to 
send mail via an email program being blocked?

Any suggestions?
