I'd guess (knowing nothing specifically about amavisd) that you need to set the hostname to a FQDN - i.e. so uname produces something like hllmx150.example.com I know nothing about ezjail - I've never found a need for it and it just gets in the way. However, knowing the jail system pretty well, there are two ways of setting the hostname. I assume ezjail writes the config files for you. The config file *should* be in /etc/jail.conf (although for backward compatibility entries can be in rc.conf). Each jail definition should have a like such as "host.hostname=hllmx150.example.com", although this could be set globally with a macro such as "host.hostname=$name.example.com", where $name expands to the jail name. Unless you have something different in the local rc.conf, this is the hostname amavisd will see. You can force it to something else in <jail>/etc/rc.conf with a line like "hostname=hllmx150.example.com". You can check it with something "jexec hllmx150 hostname". You can even use "hostname" to set it temporarily.
