Server :: Postfix Configuration To Split Mail Between Apps On Same Host?
Jul 19, 2010
I 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.

I 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.

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've setup my server by following a ton of goods, and it seems to work ok, but I need to start using my server for email in order to receive orders placed via my website. I've followed this guide - [URL] I followed the steps above, and tested the mail server via telnet, and all seemed to be ok. I tried sending an email via Squirrelmail, from cs@thinclientwarehouse.co.uk TO my working email simon@c1systems.co.uk, but the server returned with the following message:
<simon@c1systems.co.uk>: host mail.c1systems.co.uk[95.128.128.129] said: 550-Verification failed for <cs@localhost.thinclientwarehouse.co.uk> 550-The mail server could not deliver mail to cs@localhost.thinclientwarehouse.co.uk. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. 550 Sender verify failed (in reply to RCPT TO command)

I have setup a postfix mailserver and it seems to be working ok, we are only using this to relay mail to our forum users. Its not being used to recieve any email only send them out to the internet.
What is the difference between the mail.log and mail.info files? Can I turn one or both off? I see alot of messages like...
Just wondering what this string of log entries means? Also I am getting duplicates in the syslog file as well.

Two exchange servers internally. One is setup for example.com (192.168.1.10) and the other is setup for example2.com (192.168.1.20) Both are behind a single public IP.
I want to use postfix to sit in front of the two exchange servers. Postfix will accept mail for both domains and relay to the appropriate server. I have postfix installed with only defaults at this point.

I'm running a Debian LAMP server and I am adding postfix. The initial config is working and I can send and receive mail both locally and over the WAN. The problem is that I cannot get mail delivered to the user's home directory using Maildir/. I have set the:home_mailbox = Maildir/ parameter in main.cf but mail still goes to /var/mail after Postfix reload. The system is now using Maildir/ instead of mbox but in /var/mail. I really want to get mail into the user's home directory.

The problem I have is so simple yet difficult for me to resolve. My Postfix MTA allow fake mails from me@example.com to me@example.com. How can I block them?
For example, if I do "telnet smtp.mail.yahoo.it 25", as I write the MAIL FROM command I get the alert "Authentication required". How can I achieve that?

Let 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?

I did a a basic install of postfix and dovecot instead of using courier-pop and courier-imap. This is only send and receiving e-mail locally within the test network 10.7.0.X and 10.0.0.X. I used:

my postfix.conf is;

This is the error when I send an email from a local machine on the 10.0.0.X network.
PHP Code:

I've recently followed a guide I found online [1] and installed Postfix and Courier on my server machine. I can send emails from the server to any email address but unfortunately I can only receive emails sent from the server - it's only accepting emails sent locally from the host.

Iv setup a postfix mail server.. and setup my MX records within DNS. I configured the posfix mail server with the Mail accounts.I sent the accounts a test message. They end up in the Maildir for the user. But for some reason i cannot POP the mail server from a client. I can telnet to the SMTP server.. But cannot telnet to the POP3. Iv opened the ports in the firewall correctly. and even tried disabling the Firewall but when i try to Telnet to port 110 or POP port 110 i get an error saying "connection refused"

I'm trying to get my network set up. There is an internal network separated, by a dedicated firewall, from the DMZ. I'm trying to send mail from the internal network, using mutt, to the postfix server on the DMZ.No firewall is set up yet on the dedicated firewall(the whole network is, at the moment, protected by the border router) Mutt was installed with the smtp, pop,imap,ssl,sasl,gdbm options.
I thought the fact that it was compiled with the SMTP flag set would enable me to either send mail without an MTA on the same machine that mutt is installed on(internal network host) Or that i could just specify the path to the sendmail binary and not have to start postfix as a daemon ?I've found out that sendmail is supposed to be a postfix command. So i added:
Code:
sendmail="/usr/sbin/sendmail"
to /Users/me/.mutt/muttrc
But now when i start mutt i get an error saying:
Code:
/usr/sbin/sendmail: Unknown command
Obviously i started postfix before firing up mutt The permissions say that i should be able to execute sendmail as a normal user.But mutt isn't dealing with it, even though permissions appear to be correct.What do i need to do to get mail, from a normal user, over my LAN working(with mutt and postfix)?Once i have this working then i can get a proper domain name and configure postfix on the DMZ for SASL+TLS etc etcBTW i can send mail to postfix from internal network using
Code:
telnet serverhost 25
etc

I have postfix installed on 2 different boxes for 2 different domains in my network. The 2 boxes are in a single network which has a PIX firewall as the internet gateway. In the PIX the external IPs are being mapped with internal IPs of the corresponding boxes. In fact, the boxes are able to resolve the IPs of each other from the DNS. But none of them can contact each other using external IPs. They don't even ping each other with external IPs, but works fine with internal IPs. When investigated on the issue, I found that this cannot be called an issue, but this is how a network is designed (Not sure if I am right). But all the boxes can contact each other using their internal IPs.
The tweak in my mind is to specify the internal IP of the other mail server in the same network, to postfix. Is there anyway to do this?
I tried specifying the internal IP in /etc/hosts, but did not help. I came to a conclusion that postfix is not considering /etc/hosts file (Again I am not sure).

I am running Fedora 10, Postfix and Dovecot I recently changed the password of a user using the 'passwd' command. The problem is that the user can no longer receive their email messages in Thunderbird (Authentication Error). However, they can still login using SquirrelMail and get their mail.

We moved over from Cpanel using Exim. I was wondering if anyone knew of way to convert the mail so when a user logs in they get to all their mail in their folders. I notice exim has a ton of folders while postfix creates files that act like folders which contain all the emails. I sent up 1 of the emails into the our mail folder that was created by Exim and it can be Subscribed to in Outlook with imap but the emails inside doesn't show up. They both appear as text files so I don't know what the difference is.

how the whole mail server thing works, and what software handles what job. From my understanding POP3 and IMAP are protocols to pull email from a mail server, and SMTP is used to push email to a server. There are many programs that I've seen involved with creating a mail server, but I'm trying to use just Postfix. Postfix can send and receive email right?
My server runs in my basement and runs Ubuntu Server 10.10. It uses Cherokee as its web server, and it runs several other servers as well (SSH, FTP, Git, etc). My goal is to set up a mail server so that websites I run such as a Redmine or a web forum can send emails to people (e.g. an activation email for a user registering on a forum).
Anyway, I set up postfix, and now my server can receive email. I've been able to send an email from my Gmail address to drew@minipenguin.com (my server), and it works. However, if I try to send email from drew@minipenguin.com to my Gmail, it never goes through. I don't care about receiving email, as my only goal is to be able to send it.
