[MarkLogic Dev General] smtp relay on amazon ec2

I just tried this on my ML server on EC2.
Startup sendmail


	service sendmail start


Mail stuff
	mail user at domain.com
	...


Worked to 1 domain but not another.


There's nothing technically stopping you from sending email directly
from EC2, you can use a local sendmail server as above (set your mail
host to localhost) .. BUT
The IP addresses of EC2 instances are known as transient/dynamic IP
addresses and are blocked by many blacklist services so the chances of
the email getting to an arbitrary user are low.
If you are the recipient you may be able to configure your system to
allow the mail.

An alternative is to run a sendmail server from a dedicated IP somewhere
and route mail through that.

Hi,

Does anyone know if its possible to send email alerts from an instance
running on Amazon EC2?  What should the SMTP Relay be set to?

thanks
