Hi all, Stemming on the topic we just had about delivering mail via UUCP to SMTP hosts with strong protection, here is how I used to get round it for my UUCP hosts. I no longer use this config, however, due to me having no more UUCP hosts left on my system, as they have all moved to other systems.
I deligated the UUCP hosts to subdomains on hodgsonfamily.org, i.e, uucphost.hodgsonfamily.org. The system responsible for doing UUCP2SMTP is called brookfield.hodgsonfamily.org, with an ip address of 195.166.147.102. When brookfield sends via SMTP to the relevant recipient's mail server, it uses the following parameter for the helo string: helo hodgsonfamily.org I created the following DNS records: uucphost.hodgsonfamily.org. in a 195.166.147.102 uucphost.hodgsonfamily.org. in mx 10 brookfield.hodgsonfamily.org. uucphost.hodgsonfamily.org. in mx 20 backup-mx-provider.com brookfield.hodgsonfamily.org. in a 195.166.147.102 I then created a reverse zone on my ISP's nameserver to point 195.166.147.102 at hodgsonfamily.org, and set the MTA to use that helo argument. Now when someone dials into my system and uses UUCP, they send the message via UUCP to brookfield, which in turn sends it to the relevant MX record. The reverse envelope is <[EMAIL PROTECTED]>, which is looked up in the DNS, it has both A and MX records pointing to the host that is sending the mail, so it passes the DNS check, and when brookfield sends the helo parameter of hodgsonfamily.org, this passes the PTR check, and so is all well and good. I also got the system working when the user had his own domain, in this case he set the nameservers to nameservers I had control over (ns1.hodgsonfamily.org, and a number of backups), and I created the records as above: mydomain.com. in a 195.166.147.102 mydomain.com. in mx 10 brookfield.hodgsonfamily.org. [...] I never had any complaints about mail getting lost with this setup. Hope this helps, Andrew. -- Andrew Hodgson, Bromyard, Herefordshire, UK.
