Hello,
I am using following smtpd_client_restriction:
reject_unknown_client_hostname
Now, both my nameservers were offline, and postfix could not resolve IP
addresses and thus rejected all hosts:
NOQUEUE: reject: RCPT from unknown[x.x.x.x]: 450 4.7.1 Client
nd then vrfydmn
makes sure that From: matches.
In your case you can (apparently) force PHP to use fixed envelope-from
address. Than you can use this milter to fix From: address. Have a look,
it might be what you need.

d Guy2 only one. Often this e-mail is sent
in two different SMTP sessions so I don't see any possibility that
Postfix can catch that.
It's not a big deal so I have never looked into that but now I might.
The problem with using solely Message-ID is that off-list replies will
be matched with

Hi Bill
No, there is no DHCP. All I have is one interface and it's it has a
fixed IP address (192.168.34.30)

My point is: are you sure that you upgraded just postfix or maybe you
hit same issue by running apt-get upgrade or similar?
I don't know what version of Mac is still using TLS1.0 as I can't stand
Macs and avoid them at all cost. I also don't know if using TLS1.0 is
account sticky which would be ridiculous.

utright rejecting mail coming
from hosts with bad PTR/no PTR might prevent you from receiving
legitimate e-mail as well. But, as usual, it depends on your user base
and YMMV.
I've heard that gmail is rejecting / spam tagging email from such hosts
but never confirmed that myself. Maybe in some foreseeable future it
will be safe to reject bad PTR hosts but, in my opinion, not yet.

How? What restricting users to send mail only from addresses they own
has to do with mailing lists?

Also if RBL is listing google servers they doing it wrong. I just
disabled SORBS for that even though I have never hit this issue myself
as I have google CIDR records whitelisted.

voiding greylisting if some otherwise good server finds it's way to
RBL.
I also added some hosts to my list from banks, Amazon SES etc. I have
about 800 lines in the generated file, which is reasonable. I have about
60-75% passing connections whitelisted now.

Hi Bill,
Would you mind sharing which RBLs you recommend to use in postscreen?

to avoid loops. When putting script at pickup I had loops.
Check mtpolicyd, it has accounting plugin which might be what you are
looking for.

he same
connection. Final effect looks like that:
disconnect from localhost[127.0.0.1]:51596 ehlo=1 mail=63 rcpt=71
data=63 rset=63 quit=1 commands=262
I believe Matus is asking if that could be implemented in postfix so it
connects to remote SMTP server and delivers one e-mail after another
issuing RSET after each one and not disconnecting.

This expression
works for me and also removes information about the connection, which in
my case can tell if the mail was sent from webmail (unencrypted
connection from webmail host to postfix host) or client's MUA
(encrypted).
It can probably fail on some systems due to .* matching, which is
greedy, but I wrote it many years ago and it works, so I am not fixing
it.
