Yes, in another thread Didier mentioned that he didn't have a fixed IP 
address yet.

Until a few years ago I had no problem sending mail from my VMS system, 
but one by one, folks started to reject anything coming from address 
blocks assigned for DHCP usage by ISPs (it wasn't a residential / non-
residential thing; it was DHCP versus fixed IP addresses).

Around that time my ISP sensibly stopped accepting unauthenticated mail.

does not support.  I understand that Multinet does support this.

My solution at the time was to install Postfix on my Mac and configure 
that to use my ISP's gateway, including authentication credentials.  I 
could then send mails from the Mac command line, which was fine for my 
purposes then.

IMAP offers another solution, but I think we are looking at Multinet 
again there.
