I agree that expect is a much more robust way to do this. In my case the mail server is on my intranet and the connection is very robust.

PS. It looks like the To: CC: and BCC: is just for the sake of the client. RECP TO: controls who actually gets the mail.

You can also use "nc" (netcat) instead of telnet. Should be a lot simpler as you don't have to spawn a subshell.

AFAIK, expect always spawns a subshell.

The script generated with expect and using netcat doesn't look much different.
Kind of a toss up, I guess.
Code:
set timeout -1
spawn $env(SHELL)
match_max 100000
expect -exact "\$ "
send -- "nc localhost 25\r"
expect -exact "nc localhost 25\r
220 Laptop ESMTP Postfix\r\r
"
send -- "ehlo localhost\r"
expect -exact "ehlo localhost\r
250-Laptop\r\r
250-PIPELINING\r\r
250-SIZE 10240000\r\r
250-VRFY\r\r
250-ETRN\r\r
250-ENHANCEDSTATUSCODES\r\r
250-8BITMIME\r\r
250 DSN\r\r
"
send -- "mail from: me\r"
expect -exact "mail from: me\r
250 2.1.0 Ok\r\r
"
send -- "rcpt to: you\r"
expect -exact "rcpt to: you\r
250 2.1.5 Ok\r\r
"
send -- "data\r"
expect -exact "data\r
354 End data with <CR><LF>.<CR><LF>\r\r

send -- "subject : Test\r"
expect -exact "subject : Test\r
"
send -- ".\r"
expect -exact ".\r
250 2.0.0 Ok: queued as 52D7ED2060C\r\r
"
send -- "^D"
expect -exact "\$ " 
send -- "^D"
expect eof
