Important message for e-mail users on both websrv01 and websrv02
who use the POP3 mail protocol and any e-mail client (such as Outlook,
Thunderbird, Eudora, etc) which send e-mail through either of our servers.
Today we have removed the ability on both mail servers to allow
“pop3-before-smtp” authentication for sending e-mail. Previously, if you
had your e-mail client setup to check your e-mail using the POP3 protocol,
you were then able to send e-mail messages for a period of 20 minutes
before needing to check your e-mail again.
This was causing problems with e-mail users that have virus infected
Windows machines, which were then free to send their spam through our
server for a period of 20 minutes (until the POP Lock was re-enabled).
If you previous did not have your e-mail client setup to use SMTP
Authentication, then you will need to reconfigure your client to enable
SMTP Authentication before attempting to send mail through the server.
A few people have e-mailed me with questions about this stuff so far. Apparently SMTP Authentication is not enabled by default in Apple’s mail client.
Here are instructions for enabling SMTP Authentication is Apple’s Mail client:
1. Open Apple’s “Mail” client.
2. Click the “Mail” menu at the top of the screen.
3. Click “Preferences”.
4. Click on your e-mail account in the left pane.
5. Click “Server Settings” under the “Outgoing Mail Server (SMTP)” in the right pane.
6. In the new window, change “Authentication” from “None” to “Password”.
7. Enter your e-mail address for “Username” and password for “Password”.
That’s it, close those windows and you should be good to go.
