Sendmail Relaying - huh i a bit confuseled
I've got an email server up and running hosted in a server cabinate in london.
what i want to do is allow local users (i.e. the mailbox's) to be able to use the relay.
Because it will be used by people on the move i can't have an access of the connecting networks.
basically i want it to work in the same way it does with relay_local_from but i want to avoid it being used for spam.
what is the best way to secure it when i need this kind of setup, would it be to use a auth password or is there something im just not getting?
