I send you an e-mail, and you pass it on to someone else.................you have "relayed" it.
I guess you have come across "open relays"?
This issue is mostly to do with servers that do not have this facility turned off. A spammer finds a server like this and sends it a load of garbage and a list of people to send it to. Because it is supporting open relays it does it without question.
This disguises the spammer, preserves his bandwidth, and prevents him getting choked with "cannot deliver" messages if his address list is low quality.
If you cannot do someone any good: don't do them any harm....
As long as you did this to one of these, the least of my little ones............you did it unto Me.

The general definition is when someone tries to directly route mail through a SMTP server from a machine not on the same site or network as the SMTP server to another machine not on the same site or network as the SMTP server or the originating address. This has become a preferred practice for e-mail spammers and e-mail system attackers for hiding their tracks.
