Error: "Too many messages for this session" when sending email
Posted on 2009-02-18
I am running Exchange 2003 SP2 on WK23. I have a small service that sends emails to about 700 phones (not spam) and get received as text messages. I have started to monitor eventviewer and have noticed many of these errors:
This is an SMTP protocol warning log for virtual server ID 1, connection #16. The remote host "22.214.171.124", responded to the SMTP command "mail" with "421 #4.x.2 Too many messages for this session ". The full command sent was "MAIL FROM:<firstname.lastname@example.org> SIZE=700 ". This may cause the connection to fail.
Any ideas what this means or how to fix it?
