Default Can send but not receive emails (Ubuntu 7.10)


I have followed the Howto for a perfect server Ubuntu 7.10 and have installed ispconfig on top of it (plus ZEND Optimiser and ioncube loader).
Let me thank at this point the authors of these instructions for their phantastic work and dedication to the subject. Althought truely not new to computers (yes, I coded in assembler a VERY long time ago) I am certainly new to LINUX and server configuration. This allowed me to get through the install in give or take a day. Thanks again.

Now it I have an issue with receiving emails and it appears I have a few issues with DNS. I can send emails allright, but I receive nothing. There is however no message coming back telling me the email address cannot be reached (as it can). But it ends up, it seems, - nowhere. In ispconfig all services are showing 'ONLINE' status.

Here some details on my setup:

/etc/hosts localhost.localdomain localhost finch.chillifire.net finch

#The following lines are desireable for IPv6 capability]
::1 ip6-localhost ip6-loopback finch.chillifire.net
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Can anyone make sense out of that?
There seems to be also an issue regarding ssh with finch.chillifire.net, the FQDN (see netstat output). Any hints on that? May this be rlated issues?

Any input is welcome.
