Email server problem

[pcspecialist]

Hi guys, i can receive and send emails fine for my domain pcspecialist.com.au
but i cant receive external emails for foodezy.net.au and parkerweb.info which are both housed on the same server as pcspecialist.com.au
When the error log comes back in outlook it tells me relaying error
<gregparker@parkerweb.info>:
210.211.100.161 does not like recipient.
Remote host said: 554 <gregparker@parkerweb.info>: Relay access denied Giving up on 210.211.100.161.

Im using fedora core 5.0 with the perfect setup and ispconfig.
all the records are correctly entered in ispconfig.

Regards,
Greg

The MX records for all three domains are correct.
Please check if parkerweb.info and foodezy.net.au are listed in /etc/postfix/local-host-names.

that worked falko. thanks mate. now i am encountering another error. i think the aliasing has messed up too ? im getting this error ?
Remote host said: 550 <greg@foodezy.net.au>: Recipient address rejected: User unknown in local recipient table Giving up on 210.211.100.161.
is that an alias problem and how can i over come that ?

I guess the problem is that you don't have foodezy.net.au and parkerweb.info as Co-Domains in ISPConfig. If you had them as Co-Domains in ISPConfig, they would be listed in /etc/postfix/local-host-names, and the appropriate mailboxes would be configured in /etc/postfix/virtusertable.
Please add them as Co-Domains in ISPConfig.

what benefit does hosting them as co domains do bud ?
how for instance can foodezy.net.au be a co domain of pcspecialist.com.au they are two seperate sites and dont share any relationship apart from being housed on the same server with ispconfig?
The other thing i notice is when i add a new email account it removes foodezy.net.au from the mailertable and doesnt add an alias to the virtual user table. why does ispconfig do that ? and how can i change it ?

[pcspecialist]

ive also added my domains under the isp config marked line it has fixed up the relay not allowed issue but now im getting error 550 uknown host on the virtual user table. ive done the same for my users too ie greg@foodezy.net.au food_greg.

also restarted postfix at each time of editing the configs.

I was thinking all three domains were belomging to the same web site because you were wondering why receiving emails was working for pcspecialist.com.au, but not for parkerweb.info and foodezy.net.au. I thought it was obvious that receiving cannot work if the last two domains are separate web sites and haven't been configured yet in ISPConfig...

If the last two domains should be separate web sites, then create a new web site for each one in ISPConfig. Then create your email addresses in ISPConfig, and you're done. You don't have to edit /etc/postfix/local-host-names and /etc/postfix/virtusertable then.

Yes, because ISPConfig overwrites those files whenever you change something in ISPConfig. Therefore there's a line in those files (something like "MAKE MANUAL CHANGES BELOW THIS LINE") below which you can make manual additions that will not be removed. But as I stated above, this is not necessary if you configure your email addresses in ISPConfig.
