Mail is being transferred. If you want to use sendmail as a point of reference, then yes, sendmail does handle local delivery. It does so with exactly one delivery mechinism: the pipe. I would argue that the MTA (mail transfer agent) has nothing at all to do with SMTP (simple mail transfer protocol), which is simply a mechanism for clients to talk to servers and for servers to talk to other servers. What if I run sendmail in such a way that it's not listening for network connections? Is it still an MTA? -- Troy Settle Pulaski Networks http://www.psknet.com 540.994.4254 ~ 866.477.5638 Pulaski Chamber 2002 Small Business Of The Year
