email problem

[apmx0]

I set up an email account (apmx@apmx.x10hosting.com), but can't get it to work. The SMTP server seems to be rejecting all connections; I have received the following errors:

squirrelMail
Connection refused
Server replied: 111 Can't open SMTP stream.

Horde:
There was an error sending your message: Failed to connect to localhost:25 [SMTP: Failed to connect socket: Connection refused (code: -1, response: )]

mail client
The connection to the server has failed. Account: 'apmx@apmx.x10hosting.com', Server: 'mail.apmx.x10hosting.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

I have also tried to send mail to the account, but it hasn't shown up in the inbox after several hours. I have not received an error message for that, the messages just don't go anywhere.
This seems to be the same error as http://forums.x10hosting.com/free-hosting/55276-email-problem.html, which is marked resolved, but doesn't say how it was resolved.

10061 usually is that the server is not listening on that port, I noticed there you've listed your smtp server as your domain code, have you tried localhost?

I don't understand; try localhost where? The 10061 code came from Outlook express where I used:
Mail Server Username: apmx+apmx.x10hosting.com
Incoming Mail Server: mail.apmx.x10hosting.com
Incoming Mail Server: (SSL) stoli.x10hosting.com
Outgoing Mail Server: mail.apmx.x10hosting.com (server requires authentication) port 25
Outgoing Mail Server: (SSL) mail.apmx.x10hosting.com (server requires authentication) port 465
Supported Incoming Mail Protocols: POP3, POP3S (SSL/TLS), IMAP, IMAPS (SSL/TLS)
Supported Outgoing Mail Protocols: SMTP, SMTPS (SSL/TLS)

as instructed. Using localhost there would mean setting up a local SMTP server. I'm trying to use the x10 email account.
