Hi everyone,
I am currently assessing the TLS security of a Postfix mail server and among
other things sslscan reported that the server allows a (non-EC) DH exchange
with only 1024 bits. While one solution would be to only allow ECDH(E) and
disable DH(E) entirely, I would rather like to keep su

Is there an easy way to tell postfix to send a copy of every message it
receives to a “shadow server” in a way that preserves the SMTP envelope? I’m
trying to tune a spam filter on actual data, but I don’t want to do it on my
production server because the tuning is likely to break things.

Good day folk,
I ran Postfix with Dovecot as a mailbox for years now.
I noticed that, when a sender sent mails, the mailbox received it using
the date and time from the sender machine not a server one.
Which make the receiver mailbox saving the mails at the wrong time.
Please can someone help me if

Hi Daniel,
Here we use another technique. For each user that we transfer from the old
server to the new one, I just add a line in transport.cf saying the
complete mailbox name for that user and the IP or DNS name of the new

If the trusted TLS connections fails, I would like that Postfix abort the

Dear list, I've read
http://www.postfix.org/PGSQL_README.html
but there's no word about encoding. I have a postfix making SQL queries
to PostgreSQL, and can see from postgresql logs that postfix does
set client_encoding to 'LATIN1'
How can I change that to use UTF8?

You can set different rates for different destinations. For this,
you MUST READ the rest of the URLs in my response.
- specify a different (master.cf) transport for rate limited
destinations.
- specify (main.cf) mumble_destination_rate_delay values in main.cf.
- specify a (main.cf) transport map
As kindly suggested, I set /etc/postfix/main.cf: smtp_destination_rate_delay
= 2 , It does work.
but Is it possible to give different sending rates for different
destination[ip], ex, for hotmail 30mails/minute, but for Gmail, 60
mails/minute etc.
Thanks in advance.
Tony.
