I believe you are maybe mixing up 2 things. A SMTP-server accepts emails on port 25 and sends it on to another server, either another SMTP server or a mail-store (for instance cyrus or dovecot) I don't think ssmtp actually listens on port 25, but only sends email to a SMTP server that does listen on port 25. (ports can be configured, but 25 is the default SMTP-port) I actually use something similar: ssmtp on the servers postfix on my mail server ssmtp is configured to pass all email to the postfix server on my mail server. postfix is configured to either pass email on to my ISP (for outgoing email) or pass it to cyrus to store it on the mail server to allow my mail client to access it via IMAP. (POP3 is also possible, but disabled on my system) In other words, you need something like exim/sendmail/postfix/... on 'baby' to receive and store the email. The other machines only need something like "ssmtp" to send email to 'baby'. HTH, Joost
