I'm a home user with a LAN of mixed M$ and linux clients and for a year or 2 now I've run an Axigen mailserver in my DMZ
It's been an OK rather than a good experience - problems with the mailserver falling over when I'm away and losing mail, plus *endless* issues with ClamAV implementation. Anyway thought I'd try ZCS now
One useful feature I need to retain is as follows. I have 4 users (me, wife, 2 kids) and I've set up MX records in such a way that any email address of the general form firstname.lastname@example.org arrives on my mailserver and then is sorted using incoming SMTP rules into the correct mailbox
So now I want to move all that functionality over to ZCS. I've read lot's of howtos, wikis and the like and have even tried a test install (which needless to say didn't work, I'm sure coz I messed up on the DNS bit !) so I think I need a bit of help understanding all the nuances of installation
Here goes ...
I've set up the appropriate MX and A records with the ISP who hosts the 2 domains I want to receive mail for
Using online MX and DNS tools I can resolve any email address of the form email@example.com to my fixed IP and DNS records seem to work too (dig lookups return either my ISP or OpenDNS nameservers) - so that seems OK
Question 1 - hostnames
The ZCS will ultimately collect mail for 2 domains. When I install the base OS (ubuntu 8.04 server) what hostname do I give the server - should it be simply mail, or mail.myfirst_domain.com, or even mail.mysecond_domain.com. ? It seems the ZCS install.sh trys an MX check during install and in my case it should find MX records for both mail.myfirst_domain.com and mail.mysecond_domain.com., so does it matter ?
Question 2 - DNS, DHCP
At the moment my mailserver sits in a DMZ and gets it's IP from the firewall/router via a MAC based DHCP fixed lease. The lease specifies the IP (natch !), the internal IP of the DMZ interface as the gateway and ditto as the DNS server. The firewall/router uses OpenDNS nameservers itself to resolves names and then caches these, acting as a local DNS server for all the LAN/DMZ clients.
However, I'm dead confused as to how I go about adding ZCS and a split DNS to this mix
Question 3 - user.mydomain.com
Where in the config can I set up an incoming filter to redirect mails of the form user.mydomain.com to the appropriate user mailbox ?
I think that's it - certainly if I get the first 2 going properly I'm 9/10 there
Thanks for all and any guidance
