That's because of ajenti error
enter full path for file input , like this

and make sure you create file and , save it corectly

its my honor to help you , ur wlc
sorry for my bad english , and bad support

thats zone , its for ajenti, ajenti will automatically create them, its ok

ok,delete all zones, and restart bind
configure bind its very defecult ,if you miss spell something ,every thing goes wrong
you should have experiense to deal with it,

if you didnt add custom zone, delete all zones, restart bind
if you miss spell somthing or set path wrong , bind never start , and stop working

Is it your problem solved?

what do you mean by management, what exactly you try to do?

Can you send or recieve from domain on host1, if you can, so you shoud point your external domain mx records to your mail server host,
if you wann recieve mail from another domain , is not hosted on your same server
you shoud only point mx record, to your domain

tell your customer, point their mx record on your domains
external-domain.com. MX 10 mx1.your-mail-server-domain.net.

http://domainmx.net/mxsetup.shtml


if you cant get this work try this
i think in ajenti you shoud create zone for external domain , in bind
and config your external domains, config a record on host2 and config mx record on host1
like this

$TTL 604800
@ IN SOA ns.external-domain.net. external-domain.net. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
; name servers - NS records
IN NS ns1.external-domain.net.
IN NS ns2.external-domain.net.

; name servers - A records
ns1 IN A host2
ns2 IN A host2

; main - A records
@ IN A host1
external-domain. IN A host2

; mx records
external-domain.com. MX 10 host1

Actually , i didnt get your point, my english is bad
can you explain more to get me understand

what do you mean by "The domain isn't hosted local"

i have serveral customer and all of them using mail ,every thing is fine
i think i can help you

sorry for my bad English

you cant send or receive ,becuz your domain mx record shoud point on your ip server
i use bind9 dns server,and point mx record to my server ip,
