Incoming email (postfix) trouble

Hey! I just setup a virtualmin server and love it so far.

The only oroblem I’m having isn’t the server will not accept any incoming email whatsoever. It replies back to the sender with the following message. I have made sure that mail is enabled on the domains, that the accounts in question have been created and can be accessed via webmail. These accounts are also able to send mail. The server has a FQDM and I’ve checked that the domain mapping lookup tables setting is set to hash:/etc/postfix/virtual

What am I missing?

[code]This is the mail system at host latte.quacktacular.net.

I’m sorry to have to inform you that your message could not
be delivered to one or more recipients. It’s attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The mail system

<":fail:"@quacktacular.net> (expanded from the@debrin.ca): User unknown in
virtual alias table[/code]

So this ended up being something to do with Virtual Domains in Postfix configuration

I have no idea what it was. I basically deleted all the virtual domains, removed the virtual server and readded it and now email is delivered. Ugh.

Thanks for looking into it Diabolico. I’m aware of the DNS issues, I’m in the process of migrating sites (from a pair of cPanel servers) and haven’t setup my secondary DNS for Virtualmin yet (any experience with that? haha). One of the old name servers is still hooked up to ns2 so I could start bind there again if my Virtualmin box went offline.

But you still have several problems with your DNS: http://www.intodns.com/quacktacular.net and for your email:
https quacktacular.net The Certificate is invalid More Info
smtp aspmx.l.google.com Warning - Reverse DNS does not match SMTP Banner More Info
spf quacktacular.net No SPF records found More Info
smtp alt1.aspmx.l.google.com Warning - Reverse DNS does not match SMTP Banner More Info
dns quacktacular.net Name Servers are on the Same Subnet More Info

dns quacktacular.net SOA Expire Value out of recommended range More Info

smtp aspmx3.googlemail.com Warning - Reverse DNS does not match SMTP Banner More Info
smtp alt1.aspmx.l.google.com Reverse DNS FAILED! This is a problem. More Info

For SSL its ok because you are using self-signed certificate but the rest need to be sorted out. You really need to spend some time and find the solution for all this errors.
