Hi LQ!
I have many users and many domains allowed to relay post to my smtpd.
I use postfix and i have listed thos users and domains in appropriate directives like:
[quote]
relay_domains = hash:/etc/postfix/relay_domains domain.com OK
virtual_maps = hash:/etc/postfix/virtusertable user@domain localuser
check_recipient_access hash:/etc/postfix/client_access.txt user@domain PERMIT
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases only localusers in the form root:user
[quote]

That's what my logs say of some users listed but gone bounced:

It only happens for some users listed in the various lists not all of them and that's leave me a little surprised. Am i using the wrong directives for the lists ? What other maps postfix uses to allow access to some specified internet users ?
Thanks !
