Dear all, we have set up Postfix 3.4.14 in a Debian 10 host as a SMTP
relay server.
All of our hosts send mail alerts using our Postfix relay server,
using our main mail domain (suppose ourdomain1.com).
But we have realized that if we send messages using another domains
than ourdomain1.com, the m
We need to reject external mails coming from Internet to certain aliases
from our Postfix email domain, but we have to permit internal mails to
these given aliases.
In this way:
Internet --> ali...@mydomain.com REJECT
u...@mydomain.com --> ali...@mydomain.com PERMIT
Is it possible?
Special than
Jonathan Sélea

Dear, I'm receiving DMARC reports in one mail account from my domain. All
the reports coming for Google and Yahoo mainly are attached in ZIP format,
and they are XML files.
Is there any open source DMARC report analyzer for a Linux platform ??? I
prefer Debian or Ubuntu.
Thanks a lot !!!
Perfect!!!
Now I understand and I'll to start DMARC implementation with p=none to see
what happen.
Regards !!!

Dear, I have a Postfix server and I have SPF and DKIM TXT records in my
DNS. Everything works OK.
But now I want to implement DMARC, but somebody tells me not to do it
because I'd have some problems and I'll have to use a whitelist for several
emai addresses, and it's a heavy additional work.

to my Zimbra account:
dkim: FAILED Author+Sender+MailFrom signature by d=

Thanks a lot!!!

Dear, my domain is "example.com".
My cooperative mail server is an Exchange which does not implement DKIM at
all.
But also I have a Postfix mail relay for the "example.com" domain.
Is it possible to implement DKIM only in my Postfix server for all the
outgoing @example.com mails ??? Or doing thi

just SPF? Or is it possible to use an ACL defined in main.cf ?
Thanks again, good bye !!!

Hi people, suppose my domain is "company.com".
My email users are as this: u...@company.com
Is normal that I can send a mail from rob...@company.com to
rob...@company.com, from a public IP not belonging to my company?
In my case, I am at home and I execute:

People, I want to add the Zimbra repositories to my current Red Hat
server, and I can't find them anywhere.
Please can you give me the offcial Zimbra repos for Red Hat?
Special thanks
So should we use this setting for TLS options in main.cf in order to
slow down the key generation time:
tls_random_source = dev:/dev/urandom
???
Thanks again.
