Postfix - antispam and relay package

mince69meat

to patch 2.2 to accept mynetworks,BACKUP /usr/local/pkg/postfix.inc to /root dir and then edit /usr/local/pkg/postfix.inc to modify postfix declaration.

Do not backup postfix.inc file on same dir, it will break your boot.

look for 'postscreen_access_list=' and include permit_mynetworks:
postscreen_access_list = permit_mynetworks,\n\t\t\tcidr:/usr/local/etc/postfix/cal_cidr\n"

look for 'smtpd_recipient_restrictions=' (02 times in file) and include permit_mynetworks
smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination,

save file, Go to custom options in gui, declare 'mynetworks' list save config and check main.cf file in view configuration tab
Examples:
mynetworks = 127.0.0.0/8 168.100.189.0/28
mynetworks = !192.168.0.1, 192.168.0.0/28
mynetworks = 127.0.0.0/8 168.100.189.0/28 [::1]/128 [2001:240:587::]/64
"mynetworks_style = host"
"mynetworks_style = subnet" 
"mynetworks_style = class"

Hi marcelloc, knew to edit postfix.inc (would have missed postscreen_access_list, thanks), did not want to edit this file as I'm worried about braking the package on updates, can you comfirm this will not brake anything on update? was looking for a way to override just by the "custom main.cf options" to keep the package as you made it :-) and not cause problems on upgrades as I have boken things in the past by doing things my way and not the matainers way lol

some info for you, installing postfix on x64 I see that cyrus-sasl-2.1.25_1.tbz is installed as dependencie but on a x86 system it is not installed, don't know if you know that, also for the rest of the community pkg_add will not install it properly on x86 :-(

nice work and brill post about adding mynetworks, should help more on here out than just me

respect

marcelloc

The postfix in 32 bit version is not compilled every day just like 64bits. This may be something related to 2.1 working. The cyrrus-SASL has a missing dependencie that was not fixed yet, So you can only use unauth outgoing smtp for now.

About the postfix.inc, if you do the way I described, it will not broke any package update. Just insert the update on file and do not remove anything.
Package update will update postfix.inc
Do it with caution.
I'll send a line to core team asking 32bits updates.
Postix is on 2.8.7 on 64 bits and 2.8.5 on 32.

How would you use unauth outgoing smtp and get passed the "reject_unauth_destination" or is the only wayto edit /usr/local/pkg/postfix.inc as you said a few posts back?

is this line right the middle part (tcidr) just don't seem right?
postscreen_access_list = permit_mynetworks,\n\t\t\tcidr:/usr/local/etc/postfix/cal_cidr\n"

mince69meat

hope someone can help with this one, have multi wan and want postfix to send mail out of non default wan gateway, tried smtp_bind_address = xxx.xxx.xxx.xxx and it works sendding out but then incoming mail will not forward to internal mail server, any hint want to try either on pf firewall or postfix would be great

Mince

marcelloc

Did you created a wan rule to accept incoming traffic on this ip?

Another way to do it is listening postfix on loopback and then create inbound and outbound nat to your ip aliases or carp.

is this line right the middle part (tcidr) just don't seem right?
postscreen_access_list = permit_mynetworks,\n\t\t\tcidr:/usr/local/etc/postfix/cal_cidr\n"

Just include the 'permit_mynetworks,' at The beginning of postscreen_access_list.

Hi everybody,

I've just published package version 2.3 with many improvements. check first post for screen shots

main improvements:

sqlite export option to allow multiple box admins to search mail in only one box
new database structure
queue gui tab
more search options
wildcard support in search
postfix version 2.8.7 for x64bits
widget options to prevent memory limit reach in dashboard
apply permissions to non adminis users, so they can only search mail or view queue
include mynetworks to allow internal clients/hosts to send mail through postfix forwarder

mince69meat

hi all, first off, fantastic work on 2.3 :-)

now on a PF x86 box we have

Downloading http://files.pfsense.org/packages/8/All/perl-5.12.4_3.tbz … could not download from there or http://ftp2.FreeBSD.org/pub/FreeBSD/ports/i386/packages-8.1-release/All/perl-5.12.4_3.tbz.
of perl-5.12.4_3 failed!

x64 box all seens fine so far will play alot more and report back soon, hopping the above error is just waitting for the ports to update

Mince

marcelloc

mince69meat,

thanks for your feedback.

I've just fixed 32bits perl version. try again in 15minutes.

darklogic

Excellent work marcelloc, This package is really coming along very nice. Seems to be working good. The only thing I noticed after doing an update, was all my configuration seetings stayed as was, but I had to re-add my domain and point it to the internal mail server for some reason?

Thanks for all your hard work.

mince69meat

hate saying when there is somthing wrong as it feels like im ungreatfull, that said here it comes lol

pkg_add -r MailScanner don't work on both x86 & x64 "Error: Unable to get ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-8.1-release/Latest/MailScanner.tbz: File unavailable (e.g., file not found, no access)"

if you have the "Use Third part antispam" ticked it blocks outgoing mail and the outgoing mail logs report the mail as incoming

maybe warn not to tick untill mailscanner installed or have i got it wrong and VA is installed?

sorry for not getting back sooner feel asleep been working long hours, x86 installing installing now but noticed when reinstalling a newer virsion installing and now we have 2 installs pkg_info shows
perl-5.10.1_3 Practical Extraction and Report Language
perl-5.12.4_2 Practical Extraction and Report Language

not tested properly so take as just could be bug, think the logging is not loging incoming and out going properly as it seems to be logging the recipiant as the sender in some cases, more than likely a bounce massage but it should be from postmaster, will keep an eye on it but think its more than likely my bad and readding it wrong.

any tests I can do to help out just say and it will be done, as always respect, great work :-)

you might want to surgest in info below mynetworks to add 127.0.0.0/8 if adding custom unless you have this taken care of else where

there is 2 mynetworks_style = host in main.cf

Mince

marcelloc

Darklogic,

I've moved domains to it's own tab. That's why you needed to config again.

marcelloc

mince69meat,

I've started testing mailscanner package and it only works with perl version 5.10. So I've changed postfix perl dependencie from 5.12 to 5.10.

Remove both manually with pkg_delete and then reinstall package.

When you check mailscanner, you tell postfix to hold all messages, thats why you have no mail working.

I'm going to publish tomorrow the mailscanner-dev package until it get stable enough to a RELEASE version.

marcelloc

package version 2.3.1 is out with mailscanner integration (logs + options).

also mailscanner-dev 0.1 is out too.

I will start a new tread for it.

Just be sure to do have perl specific version perl-5.10.1_3.

Mailscanner-dev package uses freebsd 8.2 packages, so do not try it with any other perl version.

if you have any other perl version, i suggest you to uninstall it, any p5-module and maybe sqlite version prior to 3.7.4 you find with pkg_add.

After removing it, close console and try to install packages.

marcelloc

package version 2.3.2 is out with check_sender gui option.

perl dependencie is back to 5.12 for mailscanner 4.83.5 integration.

Hi Marcello,

I have installed this package and it really does look very good but I haven't enabled it yet - just figuring out the configuration. A bit of background:

I run my own mailserver for a couple of domains.
My ISP's mailserver redirects any mail sent to me at ISPdomain.com to me at mydomain.com.
Port 25 outbound is blocked by my ISP (fairly standard), so my mailserver must smarthost outbound emails through their mailserver. 25 inbound is open.

A couple of questions:

Is there any special configuration needed to allow for the smarthosting?
Is outbound email from my mailserver automatically subject to the same Postfix rules as email coming from my ISP or direct to my mailserver? If so, any way to bypass that?
I can't find a way to get entries into smtpd_helo_restrictions - e.g., reject_non_fqdn_hostname. Am I missing something?

Thanks,
Biggsy

marcelloc

Is there any special configuration needed to allow for the smarthosting?

Include this on genereal -> custom main.cf options:
relayhost = your.server.com

Is outbound email from my mailserver automatically subject to the same Postfix rules as email coming from my ISP or direct to my mailserver? If so, any way to bypass that?

configure your internal servers in Access List -> MyNetworks

I can't find a way to get entries into smtpd_helo_restrictions - e.g., reject_non_fqdn_hostname. Am I missing something?

choose strong on Antispam -> Header verification
I also suggest enabling postscreen and all its features

After configuring it, check main.cf file in view config tab
