Policy on E-mail SPAM
This department does not condone the practice of sending unsolicited, impersonal e-mail to people for the purposes of advertising or promotion when there is no reasonable expectation that the e-mail will be acceptable to them. Impersonal e-mail is rarely acceptable.
In an attempt to deal with this problem, we have enacted the following e-mail policies.
We do not allow SMTP relay services; mail must either be
destined for or coming from a local (csd.uwo.ca) user.
We do not accept any e-mail for delivery until the domain name
of the sender passes DNS resolution.
We categorically reject all e-mail which purports to come from
a local site but which is demonstrably not local.
We categorically refuse all e-mail from anyone listed on the
RBL+ list published by

Users who do receive e-mail spam should follow the steps outlined below before asking the Postmaster to add a user or site to the rejection list.
Is the e-mail targeted to you personally, or was it to a list
to which you subscribe?
If to a list, contact the list maintaner to see if spam can be filtered out before reaching the list.
If the spam contains any unsubscribe instructions, try to
follow them. (Yes, we realize that they rarely work, but they
already have your address...)
Contact the postmaster at the offending site and request that
they deal with the spammer. (Try to contact only the spammer's
postmaster and not all of those in any relay he is working
- Only if none of these work, or the volume of spam is extremely high, should you contact the email@example.com.
Please recognize that it is your e-mail address that the spammer's have got hold of and that they likely got hold of it because you made it public. Since you made it public, we would really appreciate your assistance in stopping the problem.
