Problem:
When sending mail through the server, getting 'socket error' or 'relaying denied'

1. If you are using your ISP to send mail, then you should contact them regarding this error.  The reason is that when you send through their server, it never goes through our server, and therefore we can't fix it. To check if you are sending mail through your ISP, look at your "Outgoing or SMTP Mail Server" name in your email configuration.  If it has your ISP's domain name in it, such as mail.att.net or smtp.netzero.net then you are using their server.  In Outlook Express, it's under Tools-->Accounts-->Properties.  Anyone using AOL's mail software cannot change or view this.   
   
   We recommend that you use your ISP's outgoing mail server, as it generally is located closer to where you are, and therefore speed is not as much an issue.  However, if you need to use our outgoing mail server and are still receiving errors,  go onto step #2

2. The first thing to make sure of when you are sending email, is that you have checked email in the past 15 minutes.  Otherwise, it will give you a 'relaying denied' message.  The servers use email checking as a way to authenticate you, so that Spammers and other people don't use the server to  send junk email.

3. To reduce the size of your messages, go to Outlook express's Tools-> Options -> Send Tab and my mail sent format is HTML. Changed it to text format.

4. Go into outlook express as normal,click on tools, accounts, mail, properties, then advanced, check your settings there
   
   i.e. outgoing mail 25
   incoming mail (pop3) 110
   Break apart 110
   
   Now try to send a message.  Be sure to 'check mail' first.

5. If you still receive a socket error when trying to send mail, the last option is to use your web-based email at yourdomain.com/webmail.  Sometimes ISPs will block users from using outside mail servers, and therefore you cannot use our outgoing mail server with your email software.
