Unfortunately, the SPAM problem has become so great that we are forced to be very strict about what we allow on our servers.

In the past, a user could be placed on a mailing list simply by providing an e-mail on a web form.  Today, this has been abused and people are being placed on mailing list by people they don't even know but who have their e-mail address.

While we are quite certain you never intend to send out unsolicted e-mail, you could be doing it unwittingly.  You can limit the chances of being accused of SPAMming by implementing a double opt-in list for all of your mailings.  A double opt-in mailing will ensure that the person who signed up on your web form gave you their correct e-mail address by sending an e-mail to the user that they must reply to to be placed on the mailing list.

In short, if you can't prove that the person who is accusing you of SPAM, willingly signed up for your mailing, you are SPAMming.

This is not to say that if you have a double opt-in list, you will not be penalized for SPAMming.  If we recieve a SPAM complaint, we will treat it as such.  It is your responsibility to ensure that we do not get a complaint.
