New subscriber Robert Bovill couldn’t send outgoing email problem from his new Internet Service Provider, so he wrote me for help in solving the SMTP authentication required problem:
Some weeks ago OE suddenly stopped sending emails with anything attached. Shortly afterward it wouldn’t send emails at all and has remained that way even after I changed my ISP from Orange to BTinternet.com.
I had too many — over 1300 — items in my ‘Sent’ tray but removing most of them made no difference. I still got an error message saying that OE is unable to complete the task but no errors were listed.
Now though it also says that my email address was rejected. Server response 530, SMTP authentication required. Emails addressed to me at [email address removed] are accepted without problem.
I tried using Windows Live and that worked for a time but then that started having similar problems. As you can see I’m now using gmail and that seems fine although I don’t care for it much. Can you suggest a solution please? I’m not sure how to carry out authentification.
I assume Robert meant Outlook Express 6, since there is not a version 8 of Outlook Express. The current version is 6.00.2900.5512.
Authentication required? That means that your ISP requires your outgoing email connection to log into their mailserver, probably using your normal userID and password for your account.
Some ISP’s do not require a log-in by the email program in order to send emails (they do, however, require one in order to download emails). They assume that, if your computer is directly connected to their network, then it should be authorized to send emails via their mailserver.
Other ISP’s are not so trusting — they’re trying to prevent their email servers from being used to send spam.
To set OE to use your userID and password to authenticate its SMTP connection in order to send emails:
- Open Outlook Express.
- Then, on the menu bar, Tools > Accounts
- Pick the Email tab
- Double-click on the email account you want to change
- Click the Servers tab
- Near the bottom, there’s a heading “Outgoing Mail Server”
- Put a checkmark in the box beside “My server requires authentication”
- Now, the Settings button will be available (previously it was grey’ed out)
- Note the options — the default is “Use same settings as my incoming mail server”
- Or, click on the radio button beside “Log on using” and fill in the account name and password.
You may have to put a checkmark beside “Log on using Secure Password Authentication” in that last step, but most ISP’s don’t use that. If you check it and your ISP doesn’t use secure password authentication, then your connection attempt will fail.
