Hey I saw your service in another forum, and I'm ready to sign up.

Say I pick up your Store and Forward package, which is exactly what I need.
That lets me receive emails on my own mail server,
but what about sending email back Out to port 25?

As I'm aware SMTP servers talks to each other on port 25, so even if I configure my own SMTP server send out at say port 26, it'll not be able to connect to another mail server unless they are listening on port 26

So, my question basically is... I'm trying to find out if your Store and Forward package also handles email out via alternate ports.

Our email store forward service solves the problem of ISP blocking inbound SMTP port,
which will cause you problems in your email servers receiving emails.

If you send out emails from your email server, the email server that's receiving emails
still receive them on their port 25, which is the standard SMTP port.
