Hi All,

I am having some issues getting outbound SMTP working.

My ISP blocks port 25 both ways except for their servers and they also don't allow relaying through their servers.

I use the dyn.com Mailhop and SMTP relaying services to get around these issues.

I have inbound mail working fine but outbound is still causing me issues.

My outbound mail ends up in the "deferred" queue because the messages get the following error: "Oct 5 06:59:59 phantom postfix/smtp[31834]: send attr reason = conversation with outbound.mailhop.org[] timed out while receiving the initial server greeting"

I can telnet to outbound.mailhop.org on 465 and get a connection BUT I don't get any response to my EHLO command.. it just closes the connection.

Any thoughts on how to troubleshoot this further ?
