Turns out I needed to add this magical line to the main.cf file:
disable_dns_lookups = yes I must have stumbled upon some older (or incorrect) information, which said the setting was the shorter disable_dns = yes. Thanks for your inputs! -later On 13 Dec 2006 19:25:45 +0100, Simon J Mudd <[EMAIL PROTECTED]> wrote:

This is probably better addressed to [EMAIL PROTECTED] but ... Without seeing your config (postconf -n) it is difficult to know what you are doing. Postfix prefers to use "real addresses" and real FQDNs and what you are seeing is probably a vestige of trying to use incomplete hostnames. Postfix also uses DNS (indirectly through the system resolver). It does not explicitly check /etc/hosts or the DNS so things like nsswitch.conf may make a big difference in how the resolver works and what happens. Again without logs (/var/log/maillog) of the failed attempts and the postconf -n output (and the version of postfix you are using) it's hard to help any more. But also check myhostname, myorigin and as Ralf said the transport maps (which don't work I think for top level domains [normally com, org, net, but in your case comp1, comp2, ...]). Use FQDNs and use DNS and you'll find postfix works out of the box without almost no configuration.
