As a sometime EC2 customer, I can tell you that AWS has no policies prohibiting use for email purposes. But, you can expect to find yourself unable to send email from EC2 due to constant blacklisting. A way to do that, if you want to use EC2 for some email services (such as mail list expansion, or IMAP service) is to of course just route your outbound email through your own servers or some service that will allow IP whitelisting or authenticated SMTP. Just be prepared to be flexible and be ready to change IP addresses often. _______________________________________________ Discuss mailing list [email protected] http://lists.lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
