Forum OpenACS Q&A: Response to Error in ns_sendmail

Posted by Nathan Reeves on
From what I understand,  ns_sendmail doesn't actually use sendmail on the machine.  ns_sendmail does all mail communication by connecting directly to the remote host on port 25.

What may be a good first test would be to attempt to telnet to the remote host on port 25 and see if you get a connection successfully.  It's sounding like ns_sendmail isn't working out the address of buildaddr correctly (either by DNS or from /etc/hosts).

If all else fails, you might want to replace the hostname you have in your nsd.tcl/nsd.ini set as your mailhost and instead use the IP Address.

Let us know how you go.
