As part of GCI’s effort to reduce SPAM through our email servers, GCI now requires SMTP authentication.
When attempting to send an email, you may see either a relay error stating, Relaying Not Allowed, or an alert box requesting you enter your password. This would be an indication you need to check Outgoing SMTP authentication on your mail client program.
Why does GCI require Outgoing SMTP authentication? In an effort to combat unsolicited commercial email (also known as SPAM), GCI requires all email accounts to authenticate with our outgoing mail server.
Customers who have established their email accounts with GCI in the last six months should already have this setting checked. If you are not sure if your account is properly setup, or need to check Outgoing SMTP Authentication to your email account, follow the steps below for your email client program.
Any device sending mail through GCI email servers will also need to enable the Outgoing SMTP Authentication. This includes cell phones, smart phones, and PDA devices.
Incoming Server Information
- Incoming Server Name (either POP3 or IMAP): mail.gci.net
- Port Number:
- For IMAP: Use Port Number: 143
- For POP3: Use Port Number: 110
Outgoing Server Information
- Outgoing Server Name (either POP3 or IMAP): smtp.gci.net
- Port Number: 25 (if needed)
GCI requires outgoing mail to be authenticated. So ensure there is a check in the box which states My Server requires authentication (different applications will have a little different wording, but all should have an option to check outgoing authentication)
