I'm confused. This seems to be running MS mail server - what does that have to do with Centos?
That is the response from my ISP's mail-server.
You've got 2 boxes? 1 is a MS mail server and the other is Centos?
I only have 1 box in this context, which is running Centos-5.4 .
Thanks for your reply. Actually, the mail was sent after a couple of hours.
I think the reason for the delay was that I gave my home email address in the From line. Now I've changed it (as below) the mail is sent at once.
Is sendmail running on Centos?
Yes
Are you sure it is running?
Yes
Is this the system from which you attempted to send mail?
Yes
How did you attempt to send it?
I sent it with a tiny python program (below)
Did you check the "mailq" command on that system?
No. But I checked that the files in /var/spool/* were all empty.
Does that system have a public IP?
No, the IP address changes quite often.
Or is it behind a firewall?
No
