Hello all,
I am using https://gitlab.com/openstrike/ratelimit-policyd to do
ratelimting of high volume senders. The software is good but I want to
ratelimit/quota sending only to external domains whereas mails to same
domain need to be unlimited/unrestricted.
When receiving the mail the software ge
released.
Bastian,
Thanks for responding. Like I said this is for few persons (who send
occasionally) and expect responses of - say a filled in tax form or
confirmation that they have submitted.

Hello team,
As part of our outbound anti-spam policy - we implement policyd/rate
limiting using smtpd_data_restrictions for senders sending say more
than 100 or 200 mails per hour.
However now-a-days due to compliance levels - certain people need to
genuinely send a burst of mails like 1000 or 2000

Hello friends,
A govt mail sender is relaying mails through one of the servers
mail-vi1eur05on2047.outbound.protection.outlook.com or
mail-eopbgr1380070.outbound.protection.outlook.com or some similar sounding
server - but I am getting the error "Sender address rejected: Domain not

Hi
You can try implementing dmarc for your domain and use dmarc check while
receiving mail.

Hi all,
Sorry for double posting (if done) as I could not locate my sent mail
while sending through my mobile.
I am curious what is the format of IP addresses in /etc/postfix/access.
i.e. will it understand 006.45.023.230 instead of the common 6.45.23.230 ?

Hello All,
I've googled but a bit confused.
I have a server with an IP hosting two different virtual domains.
Both domains need to have their individual SSL certificate like
mail.domain1.com and mail.domain2.com to download and send the same.
Is it possible in Postfix if I have only one public IP a

Hi,
if you implement Mailscanner etc you can assign a higher score based
on a header containing 163.com. Maybe that would work.
In any case everyone uses either mailscanner or rspamd on top of postfix.
You can try one of those

Advertising a primary mx and blocking port 25 for it under the assumption

In fact spammers target secondary mx more than primary mx since it is a
fact that everyone spends more time on securing and tuning the primary
server.

This mail is to get responses if anyone has faced similar issues
