Virtual domains, multiple IPs and e-mail authentication
Dear all, I have a Centos 5.2 server with Postfix 2.5.6. which handles mail for a couple of websites (virtual_mailbox_domains). Following Yahoo's and other ESPs suggestion, to send mail from different IPs, depending on their function, I would like to use 3 IPs (already set up on the server) to send out emails and also would like to sign them with both DKIM and Domainkeys. Based on your experience, I kindly ask for your suggestion, what would be the best solution to achieve this, considering the performance of the mail server. -- Attila Laszlo
Re: mailrelay - copy from all outgoing and incoming email
On Fri, November 20, 2009 7:13 am, post urne said: yes - thats right - now the mails will are stored in the lokal archive account - BUT now I get there 2 copies for one email. It seems to be, that this problem comes with use of amavisd-new as contentfilter. Is there a way, to save one mail only one time? This is a FAQ. You need to disable address rewriting either before or after the filter. See FILTER_README, keyword receive_override_options. -- Magnus Bäck mag...@dsek.lth.se
4KB of disk space burning on a single email
Hi folks, I'm just testing my postfix server for load and disk usage. I'm using content filter on some another server, and I don't feed the email back to postfix. Email data is getting deleted from my postfix server, but I don't know where 4KB of my disk space gone on every email my postfix server receives. If anybody have some idea, please tell me. -Sumit Arora

A way to trace mails flow
Hi all, sometimes (...) I need to trace the complete flow of mails through postfix queues until the delivered to dovecot (including the clients connections/disconnections and obviously the operations execute by Mailscanner). Usually I trace it with tail -f mail.log grepping sender/receiver or message id but it's a little bit silly do it every days, I notice that I can't use pid to trace these actions. Exists a logview for postfix that do that? Or a way to associate an unique id to a mail process ? Best regards.

I run a couple of forums, and would like to be able to create a page where people can create their own email address, etc, without having to email me, and have me set it up for them with a temp pass for them to change the pass later. I can handle the php end of it (i think), but am curious if there is a command line to create a new user, with a particular password for a particular domain alias? James

Probably pays to know what file system and mount options are applicable here as well. As I find it all too believable one could make a filesystem eat a block per distinct write these days. Now me, I get 24Kb of log file for every message delivered, but that includes messages about rejected spam :( I also get quite a bit of logfile entries for every message, but that does include the filtering/redirecting/sieve/. stuff that's in there as well. If people want, I can repost the logentries the OP sent me, but they are pretty standard as far as I can tell. -- Joost
Re: 4KB of disk space burning on a single email
* J. Roeleveld jo...@antarean.org: The log-entries you sent me are nowhere near 4KB in size. How do you check that the maillog increases by 4KB per message? My guess is the mails are marked as deleted. Nothing more. They never get deleted, thus the space never gets free.

Relay and mynetworks
Hi, I always think that only hosts in mynetworks can do relay on my server, but... I created the following rule smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/dominios_permitidos, reject and put this on the dominios_permitidos map meudominio.com.br OK But when I do this, all hosts that use meudominio.com.br on the MAIL FROM command are allow to use my server to relay to the outside world. Even this host don't list on mynetworks. My main.cf file is following myhostname = r01.meudominio.com.br myorigin = $myhostname mydestination = local_recipient_maps = local_transport = error:Nao aceitamos entrega local mynetworks = 127.0.0.0/8 relay_domains = $mydestination inet_interfaces = all smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/dominios_permitidos, reject If I remove this last three lines the relay becomes close. Anyone knows how to restrict relay and only accept MAIL FROM my domain? Thanks for your attention!! Jerônimo

Re: Relay and mynetworks
I put the restriction on smtpd_recipient_restriction to log all attempts to send email. There is no difference to put this restriction on smtpd_sender_restriction. Only change the time that server rejects the message. I guess.. I chance the restriction because I want that only messages from mydomain pass through the relay.

Re: Relay and mynetworks
Jeronimo: I chance the restriction because I want that only messages from mydomain pass through the relay. That is not what the configuration does. In reality, it forwards mail from anyone who sends mail with your domain name in the sender address. So put back the default smtpd_recipient_restrictions, and APPEND your sender access check AFTER reject_unauth_destination.

Same address delivering to multiple mailboxes
This is by way of a sanity check; I believe something is not possible to do in Postfix without resorting to external code, but would be very pleased if I was proved wrong. Suppose I have a catchall delivery for a (virtual) domain into a mailbox: @domain = A I also have a couple of other addresses in the same domain delivering to their own mailboxes: p...@domain = B p...@domain = C So far so good, easy to set up and things work as expected. Now for the complication. In addition to the fully qualified addresses delivering to their own mailboxes I require a copy of this mail delivered into the catchall mailbox: p...@domain = B, A p...@domain = C, A Now, providing I'm prepared to do an address rewrite I can set this up as follows: virtual_alias_maps = hash:virtual_aliases virtual_mailbox_maps = hash:virtual_mailbox_recipients virtual_aliases: p...@domain p...@domain catch...@domain p...@domain p...@domain catch...@domain virtual_mailbox_recipients: @domain A p...@domain B p...@domain C The problem is that I don't want to see that rewrite to catch...@domain being done, because of just one more little complication. Instead of delivering to mailbox A, I want mail that would arrive there sent on to another MTA, so my configuration looks like this: virtual_alias_maps = hash:virtual_aliases virtual_mailbox_maps = hash:virtual_mailbox_recipients transport_maps = hash:transport virtual_aliases: p...@domain p...@domain catch...@domain p...@domain p...@domain catch...@domain virtual_mailbox_recipients: @domain OK p...@domain B p...@domain C transport: domain smtp:[MTA] p...@domain virtual p...@domain virtual If I allow that address rewite then mail for p...@domain or p...@domain will get sent on to the MTA with an envelope recipient address of catch...@domain rather than their original recipient address. I've tried various work arounds without success. The one that seems most natural, but which DOES NOT WORK, is the following: virtual_aliases: p...@domain @domain p...@domain p...@domain @domain p...@domain This results in mail for either address only arriving in their own mailbox. Is there another approach to this that I'm missing?
Multiple IPs
