Relay access denied - receive Mails for a second domain

Question

Hello, 
 we currently receive Mails for a single domain. Now we would like to receive mails for a second domain as well. 
 The MXRecord for the second domain is already set and we do see the e-mails in PureMessage Logs. 
 When checking the log I can see the following: 
 Activity: 
 Rejected service@seconddomain.de: Relay access denied 
 
 This is how the Log entry looks like:

When looking for "relay access denied" in google, Most of the answers are related to UTM9 devices and not puremessage. 
 Thanks in advance!

Are you using puremessage for exchange or unix ? 
 if exchange, then the allowed domains must be configured via exchange connectors as exchange handles all connections (so could be a firewall rule on the box or similar) 
 If your using puremessage for unix 
 you must configure postfix by adding the domain, or wildcard domain to the transport file as a domain you accept mail for. (see main.cf and master.cf files) 
 
 In the case of pmExchange .. the program is really just a filter that exchange delivers mail to.. Im not sure there is actually a way of making purememssage reject mail unless it triggers av/as or similar rules. 
 
 try doing a telnet test to to see if your actually connecting.. or getting rejected by the firewall.. 
 
 Telnet address 25 Helo localhost Mail from: test@sub.domain.com.com Rcpt to: justin@mydomain.com 
 DATA Subject: test email From: someemail@some.cdomain.com 
 ENTER MESSAGE (blank line) . 
 you should see a message that says something like sending ID# .. etc. 
 if you dont even conect to the server, its a firewall rule. 
 if you get to rcpt to: and it fails.. you dont accept mail for that domain 
 
 if you get past both of those, you should be able to send the email.. if you dont get it.. you know its downstream .. could be an exchange rule or outlook rule.

skys the limit with pmx.. but in the case of routing and validation.. all of that config is done with postfix / text config files and postmapping the database files.. the gui is basically for configuration/policy, services and cluster management and quarantine searches .. 
 
 highly recommend checking out the postfix site directly as all of the specif examples are directly transferable to pmx. 
 
 but here is a little crash course... 
 
 the default files are in /opt/pmx6/postfix/etc 
 you should see the main.cf .. if your talking about wanting to accept mail from your own hosts, update the my networks and relay hosts.. 
 
 if your wanting to accept mail from outside domains .. depending on your configuration you will need to modify the transport file and virtual files.. then run postmap to recompile the .db file.. and restart postfix.. 
 
 ie: 
 to accept mail of abc.com and route it to aws 
 your transport file may look something like 
 abc.com aws.mydomain.mymailserver.com 
 or 
 .abc.com aws.mydomain.mymailserver.com 
 for sub domains like jimmy@domainx.abc.com 
 
 if you wish to do validation on that domain you may also need have an accept file with a list of valid email addresses 
 maye be something like 
 /opt/pmx6/postfix/etc/accept.human 
 jimmybob@abc.com jimmybob@abc.com 
 or if you had alias accounts 
 jimmybob@abc.com jimmy@abc.com 
 
 skys the limit there. 
 
 once all your config is done you will need to use postmap to compile the db files.. 
 ie 
 /opt/pmx6/postfix/sbin/postmap hash:/opt/pmx6/postfix/etc/accept.humans 
 then restart postfix

in this case to once you postmap and restart postfix.. when you do your telnet test .. you should either be accepted or dropped the second you enter rcpt to command..
