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.
