General :: Postfix 2.0.16 On Redhat Enterprise 3.0AS Does Not Deliver Mail To Outlook
Mar 16, 2011
I am a first timer in setting up a mail server. As I heard that Postfix is a very simple mail server to configure I decided to use it on the same server where we have our squid. It seems that it is really simple enough because immediately after configuring,I can send and receive internal e-mails and send external emails. As I replied to the external emails that I received myself I found out that all of them just landed on the mail queue and this is where my problem starts. I cannot make Postfix deliver the messages to my outlook mailbox. By the way, I am sending the emails the through outlook also.

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 enforced to use the Linux /etc/passwd file to authenticate myself from Outlook, Postfix will accept mail from any IPs. However, I'm not able to send mails from my Outlook via my mail server to someone else on the Internet. Am seeing the following in Postfix's log.
Code:
Mar 11 21:07:39 production postfix/smtpd[16366]: connect from pcdxxxxx.netvigator.com[203.218.211.256]

Mar 11 21:07:42 production postfix/smtpd[16366]: disconnect from pcdxxxxx.netvigator.com[203.218.211.256]
Here are my Postfix settings.

I cannot get exim4 to actually deliver any "local delivery only; not on a network".But whatever I do in the config, all mail gets frozen with entries in the log file like:"root@empty R=nonlocal: Mailing to remote domains not supported"Maybe the problem is that there is no fqdn for the computer (and will never be). How can I enable local mail delivery?

When sending a message some recipients get it while others don't and i receive this mail every time an e-mail has failed to be received by others:
Code:
Subject: failure notice
This is the qmail-send program at XXX-XX-XXX-XX.local. I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<XXXXX@XXXXXXX.com>:
Sorry, I wasn't able to establish an SMTP connection. (#4.4.1)
I'm not going to try again; this message has been in the queue too long.
Below this line is a copy of the message.
Information about my server: Plesk 9.3.0 | PHP Version 5.1.6 | CentOS release 5.4 | Linux 2.6.28.7 | GenuineIntel, Intel(R) Atom(TM) CPU 330
[url]
I use horde webmail installed through Plesk, and i access it through webmail.domain and not mail.domain

Is there an open source application that can download e-mails from a generic POP mail server, keep a copy of the mails locally and then deliver copies to multiple accounts on a LAN? I have a friend who uses a group e-mail account, and more than one person is always hooked onto that account. The problem is they cannot leave e-mail on the server, as it eats out their webhosting space, but if someone downloads a message in Outlook, the other users do not see that message.

at work place I have an HP ProLiant DL580 with RedHat Enterprise Server 5.4 x64. Today I cloned this machine using clonezilla. What I would like to do is restore the image to VMWare machine for personal purpose (I cannot perform tests on production machine). But after restoring on VMWare I got "Kernel Panic". That's normal due to different hardware.
Now, is there a way to remove the Kernel Panic and correctly boot the machine? I ask our tech department for the RedHat CD1 to enter the "linux rescue" enviromnent, then try to re-read the hardware list with
# chroot /mnt/sysimage
# kudzu

Some mail coming to my postfix server will need to be delivered local and the rest to an internal mail server.
The internal mail server is mail.example.com where there is no bob@example.com but there is a sam@example.com.
Is it possible to configure postfix to do this?

I am trying to install Redhat linux 4.0 Enterprise edition in my system. The system starts booting from CD-ROM and starts installation. It prompts for language selection(By default English) and then key board type ( By default US type). After this it is prompting to select the drivers with the following options.
" SELECT DRIVERS", "CHOOSE DRIVERS FROM LOCATION", "BACK". Why it is prompting for drivers?. what type of drivers it is looking for? what is the solution? My system mother board type is Intel 80865.

I'm trying to setup postfix (or exim, I don't mind which), so I can move away my last remaining PC from Windows.I've tinkered with Postfix for good part of a month and I can get it to accept emails using SMTP and post them to a virtual mailbox based on MySQL tables. And it rejects mail addressed to local email addresses that it can't find in the table.
First question (or problem.) I've set up Postfix to relay email it cannot deliver locally such as is the case when you send out an email. My remote host requires authentication. How can I set this up?
Second question: I want to force my clients to use either AUTH, TLS or SSL, and not allow anonymous connections (to prevent an open relay server.) How do I set that up without interfering with the smarthost setting? The smarthost login is not one of my clients, it's a pre-determined login and password that is solely used for the email relaying aspect.

I got a weird postfix setup question? This is a separate server to the one I posted about earlier today.
I need to setup a postfix server which will accept emails for local know address (full addresses) and deliver them straight to the users maildir.
Any unknown addresses (however for the same domain), needs to be relayed to another server.
This is a bit of a special setup as there is no fixed Internet connection to the server. So the plan is that local email get delivered straight away whilst emails to the same @domain, but that doesn't exist in the user tables get put in the hold queue and is later relayed to server number 2 when a connection is available.
I am using mysql to retrieve all my settings into postfix.

Can this be done? A company is currently running a postfix mail server. They got a new server and, while the users are migrated, they need to have the messages delivered on BOTH servers.
I thought it could be easily done in postfix: deliver locally AND forward mail to new server, but all solutions I found would deliver the messages in just ONE place.

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

Installation of CVS on Redhat linux
Installing CVS on Redhat Linux Redhat Enterprise 4.0
The following steps give simple steps to install CVS software on Redhat Enterprise Linux 4.0.
1) Download the tarball cvs-1.11.1p1.tar.gz
2) Run "gunzip cvs-1.11.1p1.tar". You will get file called cvs-1.11.1p1.tar.
3) Then extract this file using command
"tar -xvf cvs-1.11.1p1.tar".
4) Then go to directory cvs-1.11.1p1.
5) There you will find a file called INSTALL. Read it once carefully.
6) Now run the command "./configure."
7) Build it using the command "make".
8) Install binaries/documentation using command "make install".
9) Now open file called /etc/services and add the following lines.
Cvspserver 2401/tcp # CVS client/server operations
cvspserver 2401/udp # CVS client/server operations
10) Open file called /etc/xinetd.conf and add the following lines to that file.
service cvspserver
{
Port = 2401
socket_type = stream
protocol = tcp
wait = no
user = root
passenv =
server = /opt/bin/cvs
server_args = --allow-root=/home/cvs -f pserver
env = HOME=/home/cvs
log = /var/log/cvslog
}
11) Space on both sides of = in the above file is a must.
12) Restart xinetd services by running command " services xinted restart "
13) Check whether CVS is running on the port 2401 by using the following command "nmap IP |grep 2401". If the CVS server is running correctly it will give output as "2401/tcp open cvspserver ".
It doesn't output like "2401/tcp open cvspserver"

I have a problem in connecting from windows xp OS to the REDHAT LINUX through vncviewer. The first connection works fine. However, if I want to add more than one connection by establishing the hostname:2 through vncviewer, it stops working. I have tried modifying the file /etc/sysconfig/vncservers to add more than one allowable connections. It still fails...
