How about sending mail 500 miles more?

Just to be the man/woman/non-binary who sends mail 500 miles to your front door?

You had me at EHL0.

You just reminded me of my time working at Sendmail, where I often had to telnet to port 25 of some machine, and pretend to be a mail server sending email.

I used to be able to send all the commands without having to look them up. Not sure I could still do that today.

  • I think can still do it, 30 years after I last had to. The trauma of debugging sendmail m4 config issues for hours while the company e-mail remained dysfunctional has permanently etched it into my mind.

      EHLO example.com
      MAIL FROM:<foo@example.com>
      RCPT TO:<bar@example.com>
      DATA
      Subject: Hello, World
    
      I have crawled through the depths of hell to deliver unto you this message.
      .
    

    Wietse Venema saved us all.

    • I haven't worked at sendmail or even anything e-mail related, and I can do that… just enough e-mail fixing as side work. Let's call it sysadmin calluses.

      What made me stumble recently was having to talk LMTP to fix a mailman setup. Cheeky fuckers changed EHLO into LHLO for LMTP. (To avoid any mixups between the protocols, which is fair.)
