Having configured DNS for my home network, postfix stopped working. I've obviously missed something.

All I'm trying to do right now is send an email within my own network - e.g. from the command line on the mail server to my own user account (i.e. to my Linux user account on the server on which Postfix is running, rather than forwarding it onto another mail server or anything like that).

If I put an MX record in DNS, it comes back with the error

Oct 13 18:39:16 willow postfix/smtp[13532]: F0F25C263: to=<iain@mail.cl-office.co.uk>, relay=none, delay=0, status=bounced (mail for mail.cl-office.co.uk loops back to myself)

If I take the MX record out I get

Oct 13 18:42:22 willow postfix/smtp[13551]: 77D1C4018: to=<iain@cl-office.co.uk>, orig_to=<iain>, relay=none, delay=0, status=bounced (Host or domain name not found. Name service error for name=cl-office.co.uk type=A: Host found but no data record of requested type)

Other than this, bind9 seems to be working fine.

[root@willow postfix]# postconf -n

smtpd_sasl_path = /etc/postfix/sasl:/usr/lib/sasl2

Here's the zone file (without MX entry in this case)

[root@willow pz]# cat cl*
$TTL 3D
@ IN SOA ns.cl-office.co.uk. willow.cl-office.co.uk. (
199802151; Serial
8H; Refresh
2H; Retry
4W; Expire
1D); Minimum TTL
;
NS ns;
;
localhost A 127.0.0.1
ns A 192.168.1.11
willow CNAME ns
spike A 192.168.1.10
tiny A 192.168.1.20
router A 192.168.1.1
mail CNAME ns

Problem solved (I think).

I did need the MX entries in DNS - so my zone file now looks like this :

$TTL 3D
@ IN SOA ns.cl-office.co.uk. willow.cl-office.co.uk. (
199802151; Serial
8H; Refresh
2H; Retry
4W; Expire
1D); Minimum TTL
;
NS ns;
MX 10 mail;
;
localhost A 127.0.0.1
ns A 192.168.1.11
willow CNAME ns
spike A 192.168.1.10
tiny A 192.168.1.20
router A 192.168.1.1
cl-office.co.uk IN MX 10 ns
mail CNAME ns


I also needed to explicitely name the different hosts I might receive mail for in mydestinations in main.cf (wildcards or just the domain name didn't seem to work - is that right?)

mydestination = mail.$mydomain ns.$mydomain $myhostname $mydomain localhost $localhost.$mydomain
