Am trying to set Postfix to only allow specific machines in the network to connect and send mail through it. However, it doesn't appear that it's working properly.Some background:Test Outlook Client running on 192.168.10.11
Postfix's main.cf has the following:
mynetworks = 192.168.0.1
smtpd_sasl_auth_enable = yes
[code]....
I am trying to use Postfix as my first step in the learning to send / receive email. I have tried almost all ways but failed to send email. Linux is indeed quit difficult. I installed posfix 2.3 using yum install postfix. I dont have any DNS yet.my postfix main.cf settings are:
myhostname = example.com
mydomain = localhost (even tried example.com, $mydomain here but failed)
myorigin = $mydomain
[code]....
Here is what i do: make clean make makefiles CCARGS='-DEF_CONFIG_DIR="/opt/product/postfix-2.6.5/etc"
-DEF_COMMAND_DIR="/opt/product/postfix-2.6.5"
-DEF_DAEMON_DIR="/opt/product/postfix-2.6.5/libexec"
-DEF_MAILQ_PATH="/opt/product/postfix-2.6.5/bin/mailq"
-DEF_DATA_DIR="/opt/product/postfix-2.6.5/lib"
-DEF_NEWALIAS_DIR="/opt/product/postfix-2.6.5/bin/newaliases"
[Code]...
make install then i got this error: postfix: fatal: chdir(/usr/libexec/postfix): No such file or directory make: *** [install] Error 1 I don't understand why it's checking the usr/libexec folder for the daemons although I've set the folder to /opt/product/postfix-2.6.5/libexec in the makefile. Here is also the cat of my makedefs.out:

I was running ubuntu 10.04 for quite a while and one of our clients uses the Juniper SSL VPN connections in order to connect to them. This was working perfectly. However, this week I made a backup of my system, wiped my drive and installed Ubuntu 11.04 with which I am very happy except for the fact that the connection to this client now does not work. Every time I try to connect to the client using the ssl connection it simply says "connection time out".
I thought that it might be a setting on my machine due to the backup restores, so I did a fresh 11.04 installation on a different machine and directly after base installation tried it again, yet the same thing happened. I also thought it might be specific to firefox so I tried 2 other browsers with no luck. This does work with my credentials on my windows VM and on my ubuntu 10.04 vm though. How I get this connection working properly.
A server is acting as a router between two networks. If the load increases what happens, to the speed of network? whether the network speed will be reduced or it will sustain the same speed (Ex: 100MBps).
View 7 Replies View RelatedI recently used BootCamp on my MacBook (2.1) to partition my hdd and install Ubuntu (karmic), and I am having trouble with the wireless connection. On the mac partition it works fine, but on Ubuntu there are no wireless networks shown in the network-dialog. Previously I had only a Linux-partition on the same machine, and this was not a problem. Also the trackpad does not work at all. Does anyone know what to do about the network connection? Also I should mention that I first installed the AMD64-version of Ubuntu, which worked fine even though my macbook uses intel. Im tempted to just go back to the amd-version, any views on that?

View 7 Replies View RelatedI am trying to configure my android phone (rooted Eris running kaossfroyo 2.2) to be used as a midi controller. Which I am having enough trouble with as it is but it has raised an annoying issue that occurred a month ago when I used the phones tethering network with my laptop. After connecting the laptop to the phones network (either tether, or an Ad-hoc network created using the network manager) I am unable to switch to other networks. In other words when I'm done with the phone-laptop connection I cannot connect my laptop to my home network! When I click on the other network connection I can see that it is attempting to connect in the upper right corner of the desktop (the network icon) but it will not make the connection.
What happens is that the network indicator will make the little circle graphic as if it is trying to connect but it never will display the other circle as green indicating that it has connected. but when I disconnect from the home network that is not connecting I will get a message underneath that will say that ad-hoc network disconnected! If I am switching from the android tether it will say Android-Tether disconnected etc. Even though when I click on network manager it shows that I am attempting to connect to the home network (labeled LIBERTY in my case) upon disconnection it shows the ad-hoc or tether connection being disconnected.
I am absolutely baffled by this! The issue persists even after deleting the ad-hoc connection from the wireless settings tab!!! I would speculate that for some reason the laptop is attempting to connect to the previous ad-hoc connection despite me wanting it to connect to LIBERTY. I am very confused and hope someone can lead me in the right direction.
I've got a server running 9.10, and I'm having a few issues with SMTP. It's got Postfix and Dovecot installed, and eventually I'll add content filtering, but I need to get past this issue first.
I know there's a lot of posts out there for Postfix issues, but I haven'tbeen able to find one specific to my issue.
IMAP and POP3 work fine through SSL, and the server can send mail without any problems. That's all fine and dandy, but I need to utilize an e-mail client (like evolution or outlook). Everytime I set up a user in Evolution, the smtp connection times out, or is refused. I know it's not a firewall issue. Port 25 is open, as well as 465. So I should be able to connect through SSL. I want to be able to connect through SMTP using the same credentials as IMAP.
Here's my main.cf file:
Code:
myhostname = mail.adamwgay.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
[Code].....
everytime I get things rolling, this issue pops up. I don't know if it's something I'm setting up wrong in the client, or if it's a configuration error on my part in postfix.
I'm also having a bit of an issue with my aliases. I've basically got a lot of addresses going to root, then root going to the main user, but it's not actually delivering the mail to the main user. It sends it straight to root.
My fail2ban won't block relay attempts (it does block ssh)
mail.log contains lots of
Code:
NOQUEUE: reject: RCPT from 118-167-6-196.dynamic.hinet.net[118.167.6.196]: 554 5.7.1 <333@fgytry.myip.org>: Relay access denied

I'm getting relay access denied to an email outside of my domain. It seems the passwords are authenticating because I'm not getting invalid password prompts.

I got a Debian 6 Server running and it uses Postfix as MTA. I have set up 3 Domains and a catch all rule. My virtual file looks like this:alice@aaa.com alicebob@aaa.com bob@aaa.com bob@bbb.com bob@ccc.com bobIt works fine so far. Now I tried to add this line on top:something@aaa.com aliceand it did not work (mail gets delivered to the catch all address). It seems, it works ONLY if the part before the domain and the local recipient are equal. Does that make sense to anyone? What did I missconfigure
View 5 Replies View RelatedI have tried to find solution in existing posts but could not specifically find any with my kind of issues and hence a new post on oft repeated subject !! -- and apologies for a long long post here.Here is where I am ..On a AMD 64bit machine - I have ubuntu 10.10 desktop installed. I want this development machine to support virtual mailboxes so that I can use them from multiple apps and create real life deployment situations.I installed postfix + dovecot following the tutorials available here and current state is - I can send mails using telnet sessions and I see that the mail files are getting created in /Maildir form as I have directed in the conf files. I have configured Thunderbird mail client as well.
Issue #1: Mail sending works from Thunderbird but it always responds back with 'No mail on server' message when I try to receive mails. SMTP is configured with STARTTLS and POP3 with None (i.e. plain text password)Issue #2: Also, while going thru conf, logs and during testing - I found a few things which defer in this installation for authentication. I have given the session transcripts here.Issue #3: That being major issue - I also want to configure my virtual users to use TB client to access their mails - I did not find any tutorials or pointers towards that in my search for past few days. If I send mails to a non-Unix virtual user - the mail gets stored into /home/vmail/<domain>/<user>/new directory.Here are the conf files.main.cf for postfix
Code:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version

Has anyone managed to get postfix working using virgin media as a relay?
is there any alternative if thats my ISP? they wont give out static IP
On my virtual server I had the same issue within the last three month. The postfix daemon stopped working suddenly and I don't know why. I can restart postfix normally and it's working normally for a couple of weeks until the next crash. Does anyone have the same problems with CentOS 5.6 and postfix?

View 2 Replies View RelatedI could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.
This is the output:

View 7 Replies View RelatedI 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 was trying to write a graph plotting program with c++. I need to convert the infix expression from user to postfix expression for quick evaluation. However, the evaluation of postfix is kind of interpreted, and thus kind of slow for evaluating huge number of values. Say if I plot an implicit function the penalty is quite huge. Is there a way that I can compile the infix expression from my running graph plotting application for high speed evaluation.
View 6 Replies View RelatedI have isntalled a server with Centos 5.2 OS, now I would like to switch from the default sendmail to postfix doing a yum install postfix I've noticed there is already available an rpm version for the OS but I would like to compile my own 2.5 version, I've noticed compiling from source does not allow me to use the mail switcher to tell to the system I'm gonna use Postfix instead of Sendmail as the default MTA while this is possible when I use the "official" rpm version of the package. Now my question is this, would this be a problem? There is some specific procedure/best practice I should follow? Or once compiled and configured Postfix I can safely disable/uninstall sendmail?

I can reboot my system and sometimes eth1 is accessible from SSH, and other times eth0 is accessible. Then sometimes eth1 will just stop being pingable alltogether. This is a fairly fresh install of Debian, and the only thing I have running is VMWare Server 2.0, bridged to both of my network connections.
Here is what my route looks like:
I am fairly new to linux, I getting to grips with the offline and I am starting to be converted. The major problem I have is that I cannot get it to connect to my wireless network. I am using Fedora and my wireless card is the Belkin Wireless G Desktop Network Card - F5D7000uk (version 3000uk).
I am able to see the network and pick up the essid automatically through networkmanager or iwlist scan. I have tried to connect using Network manager:
- it picks up the information and I submit my WEP key and the icon top right shows two green dots with a blue flame(?) rotating between them for a few minutes before asking for my key again.
And using the terminal commands.
Code:
$ sudo iwconfig wlan0 mode managed
$ sudo iwconfig wlan0 essid "BTHomeHub3-12GT"
$ sudo iwconfig wlan0 key 563865428
then tried to test the connection using

It appears I have one saved (my home network) and I can connect to that, however, if I take my laptop to school or work, it will not find any networks to connect to. On a side note, I have no icon on the taskbar indicating wireless, and I used to have one. I have no idea where it went or what happened.
