Has anyone encountered a problem where they cannot connect to email-smtp.us-east-1.amazonaws.com for SMTP from a Rackspace server? WHen I ping from a rackspace server there is always 100% packet loss. So I ran a trace route and this was the result.

[root@job-server-1 ~]# traceroute email-smtp.us-east-1.amazonaws.com

It appears as though ICMP is blocked on the SES servers, so pings and traceroutes won't work regardless of where you do it from. However, my tests to connect to SMTP on the host you provided works fine from a Rackspace Cloud Server:

$ echo quit | nc -v email-smtp.us-east-1.amazonaws.com 25
Connection to email-smtp.us-east-1.amazonaws.com 25 port [tcp/smtp] succeeded!
220 email-smtp.amazonaws.com ESMTP SimpleEmailService-376766033

That is very weird, because trying to connect to it using SMTP over ssl or tsl does not work. –  Devin Dixon May 23 '13 at 21:59
    
That also doesn't explain why from my local, if I ping it, I get packets back, but not from a server instance –  Devin Dixon May 23 '13 at 22:08
