Postfix - antispam and relay package
-
Hello Marcelo, i have one question, i have a mail server behind a pfsense, one postfix mail server with 20 domains and 200 users aprox, if i install this package what is the more easy way to config this, to make my first level barrier of spam in pfsense ¿??? i don't want put all domains or users or ldap sync with my server :-( It is this possible ??

…one postfix mail server with 20 domains and 200 users...
If you are running a postfix mailserver I doubt that you get much benefit from running the postfix forwarder in pfSense. (You didn't mention postfix in your other post.) Maybe you just need to configure the postfix mailserver to do what you need.

Follow default options on gui, it will be easy :)
I don't want put all domains or users or ldap sync with my server :-( It is this possible ??
you have to configure it on pfsense to filter unknow domains, mailboxes, spf, forged sender domains, etc, etc ,etc during message header. this way, you save bandwidth while rejecting most spams before they send data.

Dear Marcello,
Thank you once again for the package ! My mail gateway is running well.
I have some questions:
- Did you updated it to 2.10.0 version? Is that correct? Because I saw on the Package Management of my pfsense box (pls see the attached file for more details).
- Does new version work smoothly? Does it has any new features? (Ex: SMTP Relay server by authentication or Trusted IPs methods)
Looking forward to hearing from you soon.
Best regards,
DQM

@DQM:
- Did you updated it to 2.10.0 version? Is that correct? Because I saw on the Package Management of my pfsense box (pls see the attached file for more details).
Yes. 2.10 is the latest stable version.
@DQM:
- Does new version work smoothly? Does it has any new features? (Ex: SMTP Relay server by authentication or Trusted IPs methods)
Yes. The new feature on gui is an helo acl and new sync code and also working on pfsense 2.1 .
I'll include some thay mem cache for postscreen. I'm running my antispam boxes without issues with postfix 2.10. -

Thank you Marcelo i try to search some information to sync ldap with my postfix server and try to make some tests, and search for get some free time :-(

I decided to auto-start my test pfSense 2.1 VM when booting ESXi - postfix failed to start and left the following log entries:

Started fine from the service status page though.

Just realized that I did an update to the latest 2.1 snap last night and forgot to re-enable postfix and pfBlocker.
Why aren't these two packages re-enabled automatically after updating, if they were enabled before?

The uninstall process disables it.

Hi Marcello,
first of all thank you very much for this excellent module! It makes my work much easier, since I am not really a postfix specialist.
I've never seen this error during package install.
check if pkg_info return two postfix installs or something.
EDIT:
Let me know if this feature works with zimbra ldap.
It's written for Active directory ldap search.att,
Marcello CoutinhoI am using the package in combination with the Zimbra mail server. When I try to do the recipient retrival via LDAP, I come to a limitation which has its cause in the different LDAP structure of Zimbra compared to MS AD. Looking at the query your module submits, I see that it is expecting a SAMAccount. This entity is not present in the Zimbra LDAP. The Zimbra LDAP structure looks like the following:
dc=tld
dc=mydomain
ou=people
uid= <user id1="">mail=u1@b.c
mail=u1_alias1@b.c
mail=u1_alias2@b.c
…
uid= <user id2="">mail=u2@b.c
mail=u2_alias1@b.c
...uid is of types inetOrgPerson, zimbraAccount and amavisAccount. Is it possible for me to modify the query in one of the config files, or does it require a change in the source code? Would you be interested in extending the LDAP part to include Zimbra queries? If so, I could prepare the query and provide it to you.
Greetings,
Burkhard</user></user> -
Hi,
maybe I found the solution: The LDAP query is nicely wrapped in the /usr/local/bin/adexport.pl, so no recompile neccessary. I did the following modification:
56c56 < our $filter = '(|(objectClass=publicFolder)(&(sAMAccountName=*)(mail=*)))'; --- > our $filter = '(&(uid=*)(mail=*))';
It seems to work and only lists userIds with valid email addresses. The technical users like spam and ham do not get selected and are not forwarded.
Does it make sense to use the filter value a Perl script parameter and make it selectable from a drop down box for Exchange and Zimbra (and potentially further mail server types)?
Greetings,
Burkhard -
ok, was a bit more complicated:
56c56 < our $filter = '(|(objectClass=publicFolder)(&(sAMAccountName=*)(mail=*)))'; --- > our $filter = '(&(uid=*)(mail=*))'; 92c92 < attrs => [ "proxyAddresses" ], --- > attrs => [ "mail" ], 163,164c163,164 < my @mails = grep { /^smtp:/i && !$gSeen{$_}++ } < $data->get_value( "proxyAddresses" ); --- > my @mails = grep { !$gSeen{$_}++ } > $data->get_value( "mail" ); 168c168 < print map { s/^smtp:(.+)$/\L$1\n/i; $_ } @mails; --- > print map { s/^(.+)$/\L$1\n/i; $_ } @mails;
I did not recognize the problem that the recipient list remained empty because all mails got forwarded to the mail server then anyhow…
Greetings,
Burkhard -
I successfully upgraded to postfix v2.10 :)
I've noticed that with this new postfix package, the file /var/log/maillog is not deleted anymore after a reboot.Does it mean that now there is a kind of logrotate configured for this file ? If yes how is it configured ?
This file is 238MB and keep growing…
-
@ics:

No log rotate yet.

hello
I'm getting this error after update postfix 2.10
postfix/postscreen[63302]: fatal: btree:/var/db/postfix/postscreen_cache: unable to get exclusive lock: Resource temporarily unavailable
any solution?
-
Did you tried stopping postfix process and removing current /var/db file to start a new one?
-
Thank you marcelloc,after stoping postfix and deleting db file it's ok now,
I will monitor logs and will inform you if it happens again -

It happened again:((

I need to configure PostFix to accept mail from a specific IP address even though that address is both blacklisted and is presenting a non-existent host name during HELO.
I have tried placing entries like this:
123.231.132.213 OK
in the "helo" section of the "Access Lists" tab, and also added them to /usr/local/etc/postfix/helo_check
but I am still getting the following reject message in the logs:
RCPT from unknown[123.231.132.213]: 550 5.7.1 Client host rejected: cannot find your hostname, [123.231.132.213]Could anyone advise me on the correct way to configure PostFix so that it will bypass the helo and RBL checks for specific IP addresses?
Thanks.
