query-source port 53; vzhledem ke zranitelnosti DNS, která se probírá v poslední době, asi nebude úplně dobrý nápad.
ifconfig eth1:2 82.100.10.215 netmask 255.255.255.192 up
ifconfig to může být zmatečné s těmi virtuálními interfacy, lepší je použít ip, který nahrazuje funkčnost ifconfig a route. Asi by to chtělo o tomhle nastudovat něco víc.
Když je v /etc/resolv.conf nastaven nameserver na 127.0.0.0 - funguje ping na doménu obsluhovanou tím bindem? funguje ping na nějaký server v internetu?

mail.mm-net.cz ? Ale to je asi jen překlep.
Pokud ten DNS na vašem serveru bude jen pro vnitřní síť, tak je nejlepší do zónového souboru dát vnitřní adresy - tj. tu 192.168.10.1 místo veřejné.
named.mm-net.cz by měl vypadat nějak takto:
$TTL 86400
@ IN SOA ns1.mm-net.cz. root.mm-net.cz. (
2008081600 ; Serial
10800 ; Refresh
1800 ; Retry
1209600 ; Expire
604800 ) ; Negative Cache TTL
@ IN NS ns1.mm-net.cz.
@ IN NS ns2.mm-net.cz.
@ IN MX 10 mail.mm-net.cz.
ns1 IN A 82.100.10.215
ns2 IN A IPadresaSekundárníhoDNSserveru
mm-net.cz. IN A 82.100.10.215
mail IN CNAME mm-net.cz.
smtp IN CNAME mm-net.cz.
Středníky do zóny nepatří. Určitě budete potřebovat sekundární DNS server (jak je patrné z konfigurace).
