Server :: Postfix Per User Smtpd Restrictions?
Feb 16, 2010
I have searched other post on here and they appear to be relevant but when I enter in the exact same commands it denies relay access to everyone. I have also used the postmap command to refresh the database.
Feb 16 15:54:48 EMAIL2 postfix/smtpd[6512]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <josh.dobs@gmail.com>: Recipient address rejected: Relay access denied; from=<msolis@EMAIL2.drewmedical.com> to=<josh.dobs@gmail.com> proto=ESMTP helo=<192.168.1.51>

Been trying for some time to get Postfix to not allow some internal users to send email externally. I have found some good resources online but none of them work. The user is still able to send email internally and externally.
I used the following web pages to assist me... [URL]

I seem to be able to install / configure Postfix server in 10 minutes as an MTA for a single domain but my struggle is really understanding the maps / restrictions which even after reading "The Book of Postfix" is not very clear to me:
[Code]....
My question is between those commonly used three maps above, what are the difference between them and how do I know when to use one over the other? Can someone clearly explain them to me? Here's what I have in my 'main.cf' but honestly I couldn't tell you if they're correct or now:

I have a user that has already used up a demo 24hr trial on my website. At present, I only check the customer id and the IP address to search for duplicates. On the whole this works but it's not foolproof. We now have 1 user from China that is changing their IP address everyday to get access to the free trial. Any options on what to do? I thought of downloading a cookie to their computer that the website could pick up - again not foolproff but most people don't disable cookies. Any other options?
I could ban China temporarily until the user gives up but if they find another proxy to chain then their IP address will be different again.

I'm looking into migrating postfix mailboxes and users from an old machine running Fedora5 to a new machine running cenOS. I was wondering, what would be the procedure to migrating over existing postfix mail to the new machine? Is it as simple as copying over /home directories and /etc/passwd etc?

I have this strange error - I switched from postfix 2.6.5 to 2.8.2 and I some mailservers cannot send mail to me. One of them was some sendmail server. I have virtual alias maps in mysql. It works fine for almost all server that are sending mail to me, but some of them seems to send mails as user@FQDN instead of user@virtualdomain my machine name is x49.tvujweb.cz, and mz email is kamil.horky@servis-it.net but in server logs is that user kamil.horky@x49.tvujweb.cz cannot be found in virtual alias maps.
here is my postconf:
Code:
2bounce_notice_recipient = postmaster
access_map_defer_code = 450
access_map_reject_code = 554
address_verify_cache_cleanup_interval = 12h
[Code]....

I am currently running a apache/postfix email service on my server. I am using aliases for two addresses for example:
trscookie@serverone.com
trscookie@secondserver.com
so the emails no matter which domain receives the email trscookie always will receive the email.
However I am unable to work out how to 'reverse' this process, for example.
If i was to go to secondserver.com/webmail I would like the emails to get sent from trscookie@secondserver.com however they are currently all coming from serverone.com. Is it possible to configure this so that it is sent from the correct domain?
Here is my main.cf:
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
mail_owner = postfix

How to create a user account on a Linux desktop machine with restrictions on connecting to the LAN, WAN, PCMCIA ports, Firewire, CDROM and generally any user controllable output options?
I have the task to set up a machine for users working with sensitive data that should not be leaving the machine where it is processed. This means disabling access to the ethernet device, lan, all other ports as mentioned earlier, and any other way of leaking the data.
In Mac OSX this was achieved using "Parental controls" from the System preferences; this even allows a selection of the applications that can be used. Under XP, Device Manager offers the option to click various devices and "Disable" them, which worked so far just fine. Some will point out that the latter mentioned OS may be easy to circumvent the security of in other ways, but that has been mitigated with other measures and it's not the point anyway. For the operator users in question, the aforementioned measure proved successful and worked.Using OSX and XP to do this was a 10-15 minutes job with testing included.
So far all guides and tutorials pointed to useradd, groups an facl, but in actual practical terms did not help at all, in fact most of the research did not render any practical results so far. I surely don't expect to point and click, and would gladly run a set of commands from CLI. If I had them. I would really would like to achieve the same restricted user account configuration in a concise, comprehensive and practical manner under Linux too. Preferably tested on humans before, and known to be workign, of course.
The machines that need to be set up are two laptops running Ubuntu. So how can this be accomplished in Linux?

I have a mail server taking care of mail for my 4 domains; the first is used for virtually all mail, the second rarely used anymore, the third is virtually 100% spam the past year(?), and the fourth isn't in use (and never has been, so no spam). What I'd like to do is to reject all mail to the third domain. Right now this is what I get (I tried to send to a nonexistent address from gmail):
[code]....
Since my username (xyz@) is the same for all domains, I could (or so I hope) change the reject message to give a hint to replace [URL] with [URL] and try again.

I've setup postfix using mysql tables and all works except for sending to an alias. The mysql logs show that postfix is only looking at the mailbox table for where to deliver the mail for the alias. However it is not looking in the virtual alias maps table. There are no complaints from postfix on startup to indicate that there is anything wrong, and if I send to a virtual domain listed as a relay on the server it does look up the virtual alias table... even though the domain is not hosted on the server....
So the question I have is where to look next? The mysql log shows the expected lookups from postfix EXCEPT for the virtual alias map queries.... why would it not be checking the table? Since it is not looking up the virtual alias it bounces the addresses back to sender complaining that the user doesn't exist... It does deliver to a virtal mailbox, however again it never checks the vitual alias table.... so it only delivers since there's a mailbox for it rather than needing an alias...

'm a bit familiar with Centos as I have set up few website on this environment but I have never actually installed, and especially, configure ftp server. Now I need to do this. Simply I need to be able to create an access account for a user and then restrict access to only one folder within the website (idea is to allow this user to upload images via ftp). I did google for ftp servers and read about vsftpd but I couldn't find any tutorial on how exactly make it work with folders and specific users.

I'm trying to configure notifying 'sys admins' cellulars about some events in clients IT infrastructure. In linux env it would be ease, just to use 'mail' cmd but need solution for windows env in this case.
I have RAID Controller running under windows xp and its raid array sotfware has feature to notify about events by email. I found some free solutions on the internet but most of them are shareware and if are freeware, they have limitations e.g. nr of sent emails per day.
Is there some free smtp server that I can use with no limitations?

so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens

I recently moved over user from an old box running postfix(v 2.0.16) over to rhel 6 running postfix (v mail_version = 2.6.6). ive tried to make sure all the files are of correct permissions and that the main.cf file is configured corectly. However there is something wrong as when i run postfix: service postfix server i get no error but when checking the status:service postfix status i get: master dead but pid file exists Looking into /var/log/mailog i find this line being the issue:
Feb 25 16:24:39 puny1 postfix/master[3517]: fatal: fifo_listen: create fifo public/pickup: Permission denied
I gather this is a file permission issue and ive tried to make sure the public folder in /var/spool/postfix is correctly set but still no avail.

I am using this config.
I'm looking to create a white-list of email addresses that are allowed to send mail to my son's email address. Basically, I'm trying to do this:
if from not in ('dad@home.net','mom@home.net','unclebill@work.org')
then deliver to 'dad@home.net'
Or deliver to /dev/null or something.
This would be only for his account/domain, not server-wide.
The configuration above uses MySQL for forwarding and authentication. I'm not sure if that is a plus or minus for what I'm trying to do.

I've tried to configure the mail service in RHEL6 but seems both sendmail and postfix can't use local user located in /etc/passwd.
Like, user Tommy and Jake they got User Unknow from maillog
Tommy:x:506:507::/home/Tommy:/bin/bash
Jake:x:507:508::/home/Jake:/bin/bash
But IF I use users' home folder not located in /home then it can go throught.mailuser2:x:513:514::/rhome/mailuser/mailuser2:/bin/bash mailuser3:x:514:515::/rhome/mailuser/mailuser3:/bin/bash

I have a RHEL 4.5 with Postfix 2.2.10 configured as a smart host for an Exchange 2003 server. Its been running well for three years like this. We have some users that are configured with alternate SMTP addresses for a secondary email domain in Exchange. One user is not getting his email for the secondary SMTP. All the others are. After some digging, the maillog indicates Postfix is not relaying his email to Exchange but to the Postfix local mail folder under /var/spool/mail. What in the configuration would cause this? His email is in the relay_recipients file as the others are.

I'm configuring a server but at this time I can't send mail. I tried using the PHP mail() function and it didn't work. Webmin says I have no mail configured. I'll be the only user and mail recipient. I've used Squirrelmail and Roundcube before and liked them.
Do I need to install Postfix in order to user Squirrelmail or Roundcube? How should I set up mail?
Here's my setup:
10.04 LTS Server edition
Webmin 1.520
Apache 2.x
MySQL 5.x

I configured my server to have the virtual mail authenticated and stored through mysql DB.Now the authentication works, but then I got the dreaded -ERR chdir error.After research and testing for ohurs I finally got it working on ONE account after I created the maildir with maildirmake.Now I am able to login and "list" messages, but nothing else. When I use postfixadmin to setup a new user, the maildir does not get created so I have the same problem.I'm trying to troubleshoot what is happening.Here are the relevant config files:
/etc/postfix/main.cf
Code:
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
