AT&T/Bellsouth Changes Effect DSL Users
Since being acquired by AT&T, Bellsouth DSL users in Louisville have experienced many changes with their service. In my personal experience (confirmed by my experiences in numerous client offices), AT&T is now blocking e-mail sent using any outgoing e-mail server other than AT&T’s.
What’s that mean? It means that, if you’re an AT&T/Bellsouth DSL customer, you usually (there are some rare exceptions) can’t send e-mail from your home or office computer using your own POP3 e-mail account (such as you might do for a domain you created using Go Daddy, Register.com or 1and1). Instead, you must configure Outlook (or any other local e-mail client you might use, such as Thunderbird) to use mail.bellsouth.net as the outgoing (SMTP) server.
Outlook 2003 users can update their settings by:
1. Opening Outlook and clicking Tools.
2. Selecting E-mail Accounts.
3. Selecting View Or Change Existing E-mail Accounts within the E-mail section and clicking Next.
4. Highlighting the appropriate e-mail account and clicking the Change button.
5. Updating the Outgoing Mail Server (SMTP) entry to read mail.bellsouth.net.
In addition, users must specify that the outgoing e-mail server use their Bellsouth username and password. Those settings are configured by clicking the More Settings button that appears in step 5 above and entering that information within the respective boxes found on the Outgoing Server tab. Note, users must click the checkbox for My Outgoing Server (SMTP) Requires Authentication and select the Log On Using radio button to activate the User Name and Password boxes.
Outlook 2007 users can access these settings by opening Outlook, clicking Tools and selecting Account Settings. Then they must highlight the appropriate e-mail account and click the Change button to update these settings to accommodate AT&T’s/Bellsouth’s network changes.
IT professionals might also be interested to know AT&T/Bellsouth appears to be blocking Telnet sessions on its DSL network, as well. Attempts to Telnet to port 25 on other servers are likewise blocked.
Using my G4 Macintosh, connected to my DSL network, I’m unable to Telnet to client’s e-mail servers. Using my G4 Macintosh, however, with my AT&T cellular broadband card eliminates that problem.
