[comp.mail.misc] SMTP through RS-232??

urban@trwspp.UUCP (Mike Urban) (01/20/87)

We're running Sendmail on a 4.2bsd system.  Do correctly
understand that the only medium that Sendmail understands
for sending mail via SMTP is a TCP/IP connection?  Is
there software available that can talk SMTP through a 
serial line (let's say a hard-wire link from Unix to
a friendly VMS machine)?

Thanks, as they say, in advance.
