In fact I've tried this. But this domain being already in
virtual_alias_domains, it looks like it's not a good idea to put it also in
relay_domains: postfix complains about this for every email passing thru:
Jun 7 15:24:18 ru postfix-mailgw/trivial-rewrite[64375]: warning: do not list
domain univ-lyon2.fr in BOTH virtual_alias_domains and relay_domains

I'm using this on MX, so that my servers are not acting as backscatters: only
valid recipients are accepted by MX and transfered to MailGW. But as postfix
won't accept using both virtual_alias_domains and relay_domains, I think this
won't do the trick.

Ok
Thank you Viktor.
