[pfx] Re: REJECT sending mails to no-reply accounts

[Bjoern Franke via Postfix-users]

Hi,



Personally, I find this type of one-way communication annoying and
impolite. The same goes for setting Reply-To to your personal email
address after asking for help on a public mailing list.



Like you did yourself?

Hi,



That was a long time ago. Postfix has evolved as the Internet has
changed. I am continuing the overhaul of this software, motivated
by people like you on this mailing list.



I just wanted to say thanks - for postfix and your support on the 
mailinglist!


Best Regards
Bjoern

Hello

My settings for backup MX server are as follows. Do you think if they
have problems? I am looking for your kind suggestions.

smtpd_relay_restrictions = permit_mynetworks, permit_sasl_authenticated,
permit_mx_backup, reject_unauth_destination

smtpd_sender_restrictions = permit_mynetworks,
permit_sasl_authenticated, reject_unknown_client_hostname,
reject_unknown_sender_domain


Does your backup mx check for the existence of the users?

I saw some people using email addresses like yahoo, AOL, mail.ru to post
messages to the lists (such as debian-user, postfix-user etc).

I am thinking those addresses which have the strictest DKIM setup are
not suitable to send a list mail, they will be blocked by many
recipients (list members).



That's where DMARC mitigation comes in place and sets a From like "Corey 
Hickman via Postfix-users " and the Reply-To 
the orginal sender - just to avoid these issues.
