Well, the usernames without the @ was the old setup we had, we are now  
trying to migrate to 'virtdomains: userid' and 'unixhirerarchysep:  
yes'. We are also passing the username plus the domain together.

At first we tried username at domain.tld@backend, but postfix does not  
like this, and it's also not RFC compliant. So this is where we're  
stuck.

We would like to keep using postfix'es  
virtual_alias_domains/virtual_alias_maps which is the way the system  
is setup right now, which correctly routes the mail *if* virtdomains  
is set to off and the user's mailboxes are in the form of  
username_domain_tld, and the routing address is  
username_domain_tld at backend.

Help on this subject would be very appreciated since we've been  
strugling on this subject for quite some time now.

Thanks,
