[warning: lots of TLAs ahoy!] No, that's not what I was saying. Exim can be configured to be many things - MSA, MTA, MDA (submission, delivery, transport agents respectively). In your case you're using it as a local MSA (submission agent) for your local MUA (user agent). Sendmail can also act as all three. Procmail is a delivery agent. Maildrop is a delivery agent too. For something to act as a fully-fledged MTA it ideally needs to be reachable over TCP/IP or some other, remote, protocol so that it can accept connections from remote systems to move messages between them and potentially other remote systems - your ISP's outbound mail server is a good example, but to muddy the waters further it probably acts in remote submission mode (ie. as an MSA) for outbound mail from customers. Confused yet? ;-) Graeme -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
