University of Waterloo -- Rejected Email
You're visiting this page because mail you've sent to someone at the
University of Waterloo has
been rejected. Probably the mail server that sent your mail has
been documented as a bulk junk mail source, or "spammer." The server may not
be generating the bulk mail itself. It could be that the software at
your site is configured to relay mail from anywhere to anywhere,
and someone -- from another site entirely -- has exploited your site's
facilities. Your site gets a bad reputation as an open
relay, and you find yourself unable to send mail to us, as well
as to many other sites.
You, of course, are not a spammer. The fact that
you're reading this means that you're a real person -- not some
mindless, mechanical, mailing machine -- and you'd like to be able to
send mail to your friend, colleague, or workmate at UW. And we'd like
FAQ for on-campus users
- Are you reading my mail?
- No! The decision to accept or reject a piece of mail is
based solely on where it's coming from and where it's going. Nobody
is checking the contents of your email.
- How can I get in touch with someone at a blocked site?
You can probably send a message to a user at a blocked site without any
trouble, but they may not be able to reply.
- Is there something I can do so that all my mail arrives?
Individual users can request that their mail
not be filtered; all mail to their userid could then get
through, including any mail currently being rejected due to blacklisting.
- I can't believe that XYZ Corporation is a spammer.
- They may not be; their mail machine may have gotten a bad
reputation for some other reason. Let us
know if there's a group we should accept mail from,
and we'll add it to our exceptions list. (Let us know nicely of
course, because we're not a mindless, mechanical, mailing machine
- I've got a uwaterloo.ca userid; why can't I send mail from home?
you get the error message "Relaying denied" when sending mail
from your computer at home, you're probably trying to relay your outgoing mail through an on-campus
machine, rather than through your Internet
Service Provider's outgoing mail (SMTP) server. Many on-campus
machines will not allow relaying of mail from off-campus sites and many ISPs
will not allow you to send mail except through the ISP's own mail servers.
Let us know!
