Re: Postfix doesn't reject empty senders

[Michael Loftis]

It is an RFC requirement to accept <> as a valid MAIL FROM  -- almost all 
bounce messages use this as well as certain other circumstances, to 
indicate they do not wish to receive a bounce message in the event of a 
delivery error.  I don't even think that postfix allows it to be turned off 
at all.

Hi
My smtp server (postfix) was receiving a lot of mails with empty senders
("mail from:<>"), and it sends them as they was from
"[EMAIL PROTECTED]". I want to change this behaviour, so I added to
main.cf the line
'smtpd_sender_restrictions = reject_non_fqdn_sender'

thinking that "<>" is not a fqdn. But after that, postfix still sends
them. So  I added
'smtpd_sender_restrictions = reject_non_fqdn_sender,
reject_unknown_sender_domain'
but this way I get the same response:

helo k
250 mydomain.com
mail from:<>
250 Ok
rcpt to:[EMAIL PROTECTED]
250 Ok
data
354 End data with <CR><LF>.<CR><LF>
fds
fdsfsf
fdsfs
.
250 Ok: queued as B4F7C3EFF
quit
221 Bye
RTFM'ing, I don't find any more option to reject this kind of senders, so
I  don't know what to do...
Am I doing anything wrong? Can anyone please help me?
Thank you very much
