Benny, 127.0.0.1 should always resolve to "localhost" (surprises can 
happen

otherwise). That's why debian puts local host name with IP 127.0.1.1
to /etc/hosts.


127.0.0.1 horus.localdomain horus localhost.localdomain localhost
::1 horus.localdomain horus localhost.localdomain localhost

but thats only used if there is no real dns server on localhost, if 
there is localdomain must be served in real dns server running on 
localhost

It would appear that the starting and stopping of OpenDKIM has solved this; 
there are no further aberrations with the statistics.  

I will be implementing a local resolver with caching - thank you for mentioning

Re: Specify good mail sender

[forums]

Sorry, I made a mistake... 

When I send a mail from SERVER1 with the user USER to my personnel mail,
I receive the mail "FROM USER@SERVER1.MYDOMAIN". 

And not "FROM USER@MYDOMAIN".

you have reject_unknown_sender_domain in sender restrictions.

your DNS servers don't apparently know "horus.localdomain"
you should better configure proper sender address in source address.


But there is also permit_sasl_authenticated positioned before
reject_unknown_sender_domain. The sending MTA should
authenticate to the relay host.

I am pretty sure that the problem is not the relay host, but the
sending machine. The relay host venus.centershock works just fine as
an SMTP drop off with the usual clients, but the sending postix
doesn't even try to authenticate.
Complete postconf -n output from both hosts would help here so just a 
shot in the dark based on a config snippet from your first message:



Local configuration is

% postconf -n
[...]
mynetworks_style = host
relayhost = [venus.centershock.net]
smtp_sasl_password_maps = hash:/etc/postfix/relay
smtp_sasl_security_options = noanonymous
smtpd_tls_security_level = encrypt


In your local config have you set smtp_sasl_auth_enable = yes ?

Re: Specify good mail sender

[forums]

I'm french, sorry for my english. 

I didn't understand anything. 

Or certainly that my explanation was not very clear. 

I retry to explain... 

_(THE LINK WAS A BAD LINK INSERTED BY DEFAULT INTO MY SENT E-MAIL)_ 

When I send a mail from SERVER1 with the user USER to my personnel mail,
I receive the mail "FROM USER@MYDOMAIN". 

But when I send a mail from MAILSERVER1 with the user USER to my
personnel mail, I receive the mail "FROM USER@MAILSERVER1". 

The postfix configuration for SERVER1 is a "basic" configuration (just
to send mail). 

_MYDOMAIN = MYDOMAIN_
_MYHOSTNAME = SERVER1.$MYDOMAIN_
_MYNETWORKS_STYLE = HOST_
_MYNETWORKS = 127.0.0.0/8_
relayhost = xx.xx.xx.xx (MAILSERVER1 IP)

The postfix configuration for MAILSERVER1 is a "SMTP" configuration
(used with dovecot). 

_MYDOMAIN = MYDOMAIN_
_MYHOSTNAME = MAILSERVER1.$MYDOMAIN_
_MYORIGIN = MYDOMAIN_
_MYDESTINATION = $MYHOSTNAME_
_RELAYHOST = [IS SMTP]:25_
_MYNETWORKS = 127.0.0.0/8 192.168.1.0/24_
_MAILBOX_SIZE_LIMIT = 2048_
_RECIPIENT_DELIMITER = +_
_INET_INTERFACES = ALL_
_INET_PROTOCOLS = IPV4_
_MYNETWORKS_STYLE = SUBNET_ 

I hope that my explanation is clearer you.

How did you send the mail?  Typically the MUA would set a sender 
address.  Is the sender set in the MUA?  We might have been able to 
tell, if you had shown us LOGS.

Right, and we could possibly tell you, as above.  But most likely 
your OS has preconfigured your mail(1) command to set a sender
domain name.

Specify good mail sender

[forums]

Hi, 

I can't specifie the good mail sender with postfix. 

I explain: 

I have a server mail cluster with 2 nodes (but only one works, the
second is going to be made). 

Node names is "node1" and "node2", cluster name is "node". On node1, the
server name is "node1" and the mail server name (for postfix) is "node".
The servers are on a personnal domain (my_domain.fr). 

On all of my servers (mail servers and others), the postfix
configuration is: 

. 

mydomain = my_domain.fr 

myhostname = server_name.$mydomain 

. 

(with "node" for relay to others servers and mail server configuration
for "node1") 

When I send a mail from a local server (linux) with a linux user, I
receive the mail with "from user@server.my_domain.fr" [1]. So, that's
OK. 

But when I send a mail from the mail server with a linux user, I receive
the mail with "from user@node1" [1] instead of "from
user@node1.my_domain.fr" [1]. 

I don't understand where is the bad configuration.

The recommended way is via a policy service which checks with the 
imapd, and causes a rejection for overquota recipients.  Dovecot 
actually includes such a policy server.  Refer to the Dovecot wiki 
for use and setup instructions.

your DNS servers don't apparently know "horus.localdomain"
you should better configure proper sender address in source address.

postfix 3.3.0 and vda quota patch

[Roberto Sebastiano]

Hello,

it seems that "postfix vda" patch that brings quota support for virtual
maildirs is not updated / not mantained anymore. There is no patch for
3.3.0
http://vda.sourceforge.net/

I used that patch to create a custom mailserver on ubuntu 10.04 and 14.04,
but 18.04 uses postfix 3.3.0 and i'm stuck.

Is there any way to achieve the same result (maildirsize quota and
overquota replay) without the vda patch at this point ?

Thank you,
Roberto S.
