still the way to deal
with such situations in 2020?
There is not much we can do to get rid the forwards, and we have many of
them, so a good solution would be welcome. :-)
We are running debian 10, btw.
Thanks!

l users.
Also...perhaps consider running it on a seperate machine. (perhaps even
a VM on your samba ADDC)

Hi,
I'm not able to suppress the DOMAIN element of the username part on
*this* machine.
All the machines in the AD have a directive in their
username, and not a local
account, or DOMAINB\username.
But in common practise, we never login anywhere with DOMAIN\username
And we also never have the issues you are describing, and no need fotr
mappings of any kind.
Are you *sure* you need your usernames in that format?

would consider delivering mail back to the mailbox of u...@ourdomain.com
or maybe postmas...@ourdomain.com
So, if I understand correctly, I would set something like:
sieve_redirect_envelope_from = ""
(dovecot.conf)
Thanks again!
MJ
like to prevent NDRs for these
sieve-forwarded messages.
Is there a way to achieve this?
If it helps: the sieve-forwards are mostly to very few foreign domains,
so perhaps we could filter NDRs at some stage, based on coming-from
domain..?
Best regards,
MJ
i b e will probably get rid of this.

fixed the webform.
Your solution works super, thanks a lot!

REJECT
I postmapped the file and restarted postfix.
Alas... postfix is still happily forwarding emails to 1...@mail.ru to my
smarthost.
How can I make sure that this particular postfix instance will DISALLOW
sending ANY email to @mail.ru?
What am I missing?
Thanks in advance!

Hi,
The question can perhaps be made more generic like this:
Can postfix generate a

(with instructions who to contact to revert the situation) it would be
very easy: only move the user to the specific OU, and have the system do
the rest.
Can this be done?
(postfix 2.11.1 from debian wheezy, yes we know we should upgrade, and
we also will, but it runs rock solid...)

This way you protect the identity while it is transported from the client to
the server and you are able to store the passwords cry

Ok, so disallowing LOGIN is not a clever move :-)

Right! Remove permit_sasl_authenticated and keep check_sasl_access

Thanks! It works!

there a way to restrict that?
A simple list of usernames would work, or more advanced: dynamically
using an ldap lookup to check group membership.

ed using this form, but you can describe
the time-out with large messages.
Along with Postfix rate-limiting features, this should improve delivery
with Yahoo MX.

ame problem for large messages sent to Yahoo. (including
yahoo.fr, yahoo.co.uk etc.)
I don't think that it's a Postfix problem at all because only Yahoo
causes this, so it much more likely to be a Yahoo problem.

I have no trouble with reverse IPv6 DNS in my postfix headers. Looks
like a local DNS config error or mis-delegation.
Either way, I don't think it's a postfix issue at all.

Use the notation with the square brackets:
[::1]:10028
They are used to differentiate the colon used for separaring the port,
as opposed to a colon which is part of the IPv6 address.

Also check SElinux if you are running this. It may prevent changes to the port
config from taking place.
You can see entries in the logfile called /var/log/messages

What I meant Martin was that there was a space in the "destination" word, which
was written as "destina tion" rather than "destination".
If you make
smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination
Does it work?

Dear Wietse,
thank you for your detailed explanation.
In the future, would you consider having unique identifiers generated
by an algorithm which would take into account the CPU ID (or other
unique identifier), process ID & time, so as to make it a unique ID
worldwide, or is this not something whi
Might kill
all spam, but will also kill legitimate emails, and I'm not sure how your
clients will know about an email they did not receive. As others have said,
be careful because this might bite you back at some point.
On the other hand, it's your network so do as you see fit.
Cheers,
router is the same command.
Regards,
Olivier

im server would have said "STARTTLS command used when not advertised".
check your docs on how to disable smtp filtering in your firewall (look
for somthing like "no ip inspect name yourrulename smtp"...).
That solved it! Thank you very much to you & Noel.
