Which smtpd_recipient_restrictions?

Hi,

What smtpd_recipient_restrictions do people tend to use/recommend?

I was finding that reject_unknown_hostname was blocking a lot of genuine
mails - obviously there are a lot of badly configured mail servers out
there, so now i'm using this:

smtpd_recipient_restrictions = permit_mynetworks,
permit_sasl_authenticated,
reject_invalid_hostname,
reject_non_fqdn_hostname,
reject_non_fqdn_recipient,
reject_non_fqdn_sender,
reject_unknown_sender_domain,
reject_unknown_recipient_domain,
reject_unauth_destination



Thanks!
