Hi,
I was wondering if fellow Postfix users would still recommend using amavisd-new
when integrating AV (ClamAV), and spam filtering (SpamAssasin) ?
The site I have this in mind for receives a moderate amount of e-mail per day.
This appears to be the most mentioned configuration via web searche

There's nothing wrong with Amavis. The only decent alternative I know of

Hi,
We have postfix-3.1.4 set up on fedora25 to use submission for
outbound mail. How can I control the number of recipients that can be
addressed in any one email?
Below is my submission config from master.cf. Perhaps it would just be
setting smtpd_recipient_limit specifically for submission?

Nothing at my fingertips. Note that Postfix TLS support is based on OpenSSL,
and OpenSSL is not vulnerable
Well then that settles that. The press reports made a muddle of this. Thanks.

Think you are missing something like this in main.cf

Yes and also it is recommended to setup different selector for each server and
different key per server.
You can test DKIM signature using this website:

dkim runs on 8891:

This way it will sign the mails, that way you should see something like

Hi Maarten,
Apologies - I missed this when I was copying my setup.
I already have these lines in my /etc/postfix.main.cf file.
When an e-mail comes in, I'm seeing these lines in the maillog:

Check /etc/opendkim.conf. And the line that Says Mode.
You probably have it set like this:

Change it to:

So right now since it's set to only verify incoming mail signtures you

I'm not sure I fully understand what you are saying.
So I should have created a separate 'default.private' for each server ? How
