Server :: Postfix Configuration: How To Restrict Use Of CC
Jan 17, 2011I have configured postfix on my server.
telnet mydomain.com 25
helo validdomain.com
mail from: validaddress@validdomain.com
rcpt to: validuser@mydomain.com
[code]....
When I run this test, as expected, the email is delivered to validuser. However, postfix also delivers it to user1 and user2 despite the fact that the sender does not belong to my domain. I have implemented client, helo and recipient restrictions as below. How do I prevent the malicious use of CC as described here?

smtpd_client_restrictions = permit_mynetworks,

Server :: Postfix Configuration To Split Mail Between Apps On Same Host?
Jul 19, 2010I have an OpenSuse 11.2 system that is running 2 BBS systems independently, both of which are capable of receiving smtp mail on prot 25. What I would like to do is set up Postfix on the OpenSuse OS to receive all mail for both those domains and then send the relevant mail to the correct BBS. I would therefore have Postfix listening on Port 25 External and the 2 BBS applications listening on different ports on the localhost address. At least that is the plan.
how to do this. I want to do it and still make sure Postfix is secure and not accidentally open up any nasty relay holes etc etc.

Debian Configuration :: Tests And Playing Around With Postfix In A Test Squeeze Server?
Feb 15, 2011I'm doing some tests and playing around with postfix in a test squeeze server. What I want to achieve is a postfix mail server using ports 465 and 587 with smtp authentication to send mails. I followed this howto: [URL].. and I'm using a php script with pear functions to test sending emails to a gmail test account of mine. This is the script:
<?php
require_once "Mail.php";
$from = "Webmaster <webmaster@server>";
$to = "My Name <myaccount@gmail.com>";
$subject = "This is sent with pear as a test";
$body = "This is the body of the message";

OpenSUSE Network :: Mail Server Configuration - Postfix To Send Incoming Emails To A Php Script Or Perl
Aug 13, 2010I have a server with a domain running and im trying to resolve the mail server but i can't see where to start. I use OpenSuse 11.2. Basically, for starting, i want postfix to send incoming emails to a php script or perl. for outgoing emails i guess that i could use php mail function and i will see what else to have. I configured the dns. I do a dig.mydomain.tld MX and i get the following:
mydomain.tld3600INMX0 mail.mydomain.tld
mail.mydomain.tld 3600INAmyNumericalIp
So now my system is receiving MX content but i dont know what to do.

Oct 4, 2010so 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

Feb 25, 2011I 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.

Ubuntu Servers :: Postfix: How To Get The Configuration
Jan 3, 2010I have a postfix server running on a virtual machine hosted by vpslink.com. I have followed the following configuration guide to install the system with dovecot, sasl smtpd authentication, and postfix as an mta: [URL](I know it says it's a debian configuration, but it seemed legitimate that I could follow it). Anyway, in sending email from my primary email account, I have found that roughly 1/2 of the messages are delivered, and 1/2 of them are rejected with a message similar to the following:

Ubuntu :: Postfix Smtp Configuration
May 13, 2010I'm running Postfix primarily as a local email server. There is no email coming in from other machines, and there are no other machines using it to send mail. But I'd like it to be able to send mail. I use Evolution for my normal email stuff, and it's configured to send mail to my ISP's smtp server, and that's working fine. But I occasionally send mail from the command line, using the "mail" or "mutt" utilities. (Mutt because the standard mail doesn't support attachments.) These don't use Evolution's configuration, they depend upon whatever is listening to port 25 - and that's Postfix. So all I should need to do is to give Postfix the smtp server, user name, and password. My problem is that Postfix has voluminous documentation online, and I haven't been able to find this simple configuration in it.
View 3 Replies View RelatedDebian Configuration :: Postfix Bad IP Syntax Support
Apr 23, 2016I have currently configured Postfix as an SMTP server. I would preferably not use a domain name in my email address, like so: myname@[1.2.3.4]
I'm currently testing to see how other mail servers handle this kind of address. When I sent a mail with one one of my gmail accounts, I see that the mail gets rejected due to bad syntax.
It seems as though Google is giving me a RCPT TO address like so: myname@1.2.3.4 However, the postfix server rejects this address with the following error:
501 5.1.3 Bad recipient address syntax
To my best knowledge the only way to have an IP address inside an email address with to write it as a domain literal [1.2.3.4].
My question: how to configure postfix to accept myname@1.2.3.4 as well?
I have put both [1.2.3.4] and 1.2.3.4 in "mydestination" and 1.2.3.4 in "virtual_alias_domains".
It doesn't seem to work so far though.
Fedora Servers :: Recommended Postfix Configuration For SB?
Mar 27, 2009I am building an email server in what I consider to be a 'small business'. I would say my Postfix mail server will house 300 mailboxes (Max). I have a decent server with enough RAM / disk space to run this email server however I don't know what the best way is to manage / configure the users mail boxes.
how to create a new user on the Linux server using 'adduser / useradd' and then setting their shell to /bin/nologin. This is because the mail user will never need to log into the shell of the mail server directly and can still populate email from their mailbox which is located in their /home/$user directory. Now many people I spoke with have advised me that this is a bad and cumbersome method of account administration.
I am running:
Postfix 2.5
Clamav v0.94.2
Amavisd-new 2.5.4
Dovecot 1.0.7
Spamassassin 3.2.5

Debian Configuration :: Postfix - Cannot Currently Create Any Folders Other Than Inbox
Jun 20, 2011My Postfix cannot currently create any folders other than inbox. Even when I send an e-mail I receive an error along the lines of, "Could not create sendmail folder." Also, my Postfix isn't receiving e-mails, and can only send e-mails to other accounts on the server. I called my ISP and they told me my port 25 isn't blocked, and it is forwarded on my router so I am not sure what could be wrong. I am using zoneedit as my name server and I am pretty sure my MX record is good.

Debian Configuration :: Postfix Not Delivering To Local Users / Sort It?
Mar 24, 2011I did search the forum but didn't find an answer.
I have setup Postfix + Dovecot on my basic debian 5 server. If I send a message to a localuser@mydomain.com from mutt, it delivers just fine and is visible when viewed through squirrelmail, I can also send just fine.
My issue is that irrespective of what options I set in main.cf, I cannot for the life of me get Postfix to stop erroring with "Recipient address rejected: User unknown in virtual alias table". I'm stumped.
My main.cf is as follows code...
I do not want to setup virtual hosting with MySQL or similar, I literally want to receive mail in local users mailboxes for a single domain. Any ideas on what's missing?
Ubuntu Servers :: Postfix Smtp Client Configuration For Port 465?
Jan 2, 2010configuring my postfix server to send mail over smtps port 465. My ISP (as is the case with many ISPs), is blocking outbound SMTP, so I need to configure postfix to relay my mail out through my ISPs SMTP servers.
I was able to get it to work with gmail, which uses port 587, by using SASL: [URL] but that configuration is less than ideal as gmail drops the "reply to" address so when people receive my email, it looks like it's from gmail instead of from my server.
If I use my ISP SMTP servers as a relay the "reply to" address is not stripped, but the relay uses ssl over port 465 instead of TLS. According to the SASL readme:
Quote:
Postfix does not deliver mail via TCP port 465 (the obsolete "wrappermode" protocol). See TLS_README for a solution that uses the "stunnel" command.
I've looked at the TLS_README and can't figure out what I need to do. how to configure this?
Ubuntu Servers :: Postfix Configuration - Send Mail To Other Domains
Nov 5, 2010Let me start off by saying I am experienced with computers, though my knowledge of Linux and networking is limited. I've just recently started setting up a Ubuntu 10.04 server to be a SMTP server. I've followed this guide by the letter: [URL] What I've attempted, to test the server, is the following:
telnet localhost 25
ehlo localhost
(this returns all the desired information) I then do a MAIL FROM my domain which is accepted, and try to do a RCPT TO an external mail server (gmail) to test sending an email. I am then told 'Relay Access Denied'. I'm sure that there's something fundamental that I'm either not understanding or not doing correctly. I simply want an SMTP server that can send to other domains. What do I need to do?

For the past two days I have been in and out of the logs, changing parameters and blindly following tutorials but I can't get anything to work properly. So far I've narrowed my problems down to tls connection establishing and a failure to authenticate, judging by the local emails I've received from "The mail system".
