I would like my DB Admin e-mail to be an alias, but it seems that the Links e-mails will onyl be sent if I enter a POP account. Is there a way to get around this?
That has to do with the way your ISP/sendmail is configured. Try adding the -f parameter (I believe it's "fake") and see if that works on the sendmail command.
At any rate, it's _NOT_ a Links issue, it's a Unix issue.
