I've installed Ispconfig on Ubuntu Dapper using the guide provided and I love the setup. I'm hosting the first 2 domains and everything is working flawlessly. Except for mail for one of the domains.
Since I'm hosting the DNS entries externally at another ISP (to have MX backup if my server goes down) I've assumed that I do not need to use any DNS features within Ispconfig nor create DNS any entries on this machine. Right?
Everything works perfectly for the first domain (weavebrain.com.au) - web & email arrives and can be sent.
However problems with my second domain (kalyanamitta.net) - mail sent to a user does not arrive
. I can send mail from the kalyanamitta.net account but replies sent to it do not arrive. WHY????
My DNS entries are:
The other site details (where the mail works) looks like this
So in fact the format of two DNS records is identical, but why is weavebrain.com.au mail arriving and kalyanamitta.net's mail does not????
