Support - POP Before SMTP
The mail servers are set to POP before SMTP as a security measure to prevent SPAM.
The mail server collects your IP address when you authenticate yourself with the POP server, and then permits SMTP relaying from that IP address for a short period of time (Adhost is 15 minutes).
This means that you MUST check your incoming mail before you will be allowed to send mail.
If you set your email client (like Outlook) to check your mail regularly, your outgoing mail may sit in your outbox until the incoming mail is checked again.
If you only check mail when you initially open your email client, you will need to force a send/receive before your outgoing mail can be sent.
If you do not check email within 30 minutes, you may receive an error that says "Error 554: Relay Access Denied".
How to resolve this issue:
Quick Fix
- Move anything in your Outbox to your Drafts folder.
- With nothing in your Outbox, click Send/Receive.
- After a successful Send/Receive, try sending an email from your drafts folder.
Long Term Fix (in Outlook 2003)
- In Outlook, go to "Tools" then "Email Accounts".
- Click "View or change existing e-mail account", then click "Next".
- Select your account, then click "Change".
- Click "More Settings".
- Click the tab labeled "Outgoing Server".
- Select "My outgoing server (SMTP) requires authentication", then select "Log on to incoming mail server before sending mail" at the bottom.
- Click "OK".
- Click "Next".
- Click "Finish".
