It could be any e-mail sent to the parl.gc.ca site. Everything sent to us will be filtered and analyzed to make sure it's a valid e-mail.
When I say “reject”, it means it's a bad e-mail; it's not a valid e-mail. It's an attempt to corrupt or deny services, an e-mail that has no real value.
If we have any doubt about that e-mail, but there's no virus or anything, it will be delivered to you, and then we'll identify the level of spam. If we believe this could be spam, it's for the members to decide what to do with that e-mail.
That's the way things work.
