Re: Sieve reject at SMTP time possible with which implementations?

The problem with filtering before storing in the end users mailbox is as
says, the concept of the mail envelope.  At the SMTP level, the envelope
probably has many recipients, so who's configuration do you use?  It's
when you are about to put a message in a users INBOX will you know that
can take action on behalf of all the recipients (cos there is only one).
Hence when MailSite rejects a message at the SMTP level it is using a
server level script.

You can reject per Recipient and accept others. Nothing wrong with it.
You can do this per domain or recipient, the recipient could modify this
configuration option and the data could be in a SQL or LDAP server.
