I'm trying to change some configurations but when I change it from the default options in main.cf, it doesn't actually update the running configuration. I've even restarted the server all together but it still doesn't update it.In main.cf, here is the configuration I've added:
bounce_template_file = /etc/postfix/bounce.cf
bounce_queue_lifetime = 4h
maximal_queue_lifetime = 4h
delay_warning_time = 1h
I have a lightweight admin background, but good enough to set up most servers. I have switched from sendmail to postfix for the first time, but I keep going around in circles on the following...
In sendmail, I used to maintain a table (mailertable) where I would redirect email like this

We have been struggling with a problem with the mysql-server package. This might be in the wrong category because our problems are with it on x86_64. Where the problem happens variables that should populate from the my.cnf don't, on other servers, they do, the my.cnf files are identical except for the server-id
The problem occurs on some of our machines but not others. All are using the mysql-server-5.0.45-7.el5.x86_64 The ones that work, when you connect with a client respond with server version 5.0.45-log source distribution The ones that don't work respond with 5.0.45 source distribution
It's unclear what the differences are between the two source versions and how we wind up with two different versions. One thing that might be involved, the mysql package is installed with both the i386 and x86_64
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

When I send an email via TLS I see the following log entries.
Code:

What I'm really curious about is there is an intial TLS connection with a 256 bit cipher, but then.. The last entry states "sasl_method=PLAIN" - so surely this is not encrypted? Or am I misunderstanding how it works?

I am new to Linux and I am trying to set up a mail server using postfix. I have done all the configurations(hopefully correct) and all the test seems to work except 2 things.
1) Postfix is running but when I try to restart the service it always fails. I checked the /var/log folder and there are no error messages.
2) When I try sending e-mails using outlook, outlook fails to connect to my server.
I am wondering if I have done the configurations properly. I am a little confused in regards to hostname and domain name. When I do a hostname on the terminal I see the hostname that I gave my server. When I do the domainname command however, domain is none. Is it necessary to have a domain to configure postfix? I have myhostname = my.hostname.com what should my domainname = to if there is none. If I do require a domain name how to I create one? I need to be able to access e-mail from external clients.
the mail server itself will receive mail, that part works. i'm using dovecot imap to grab my mail, that works. but if i try to send mail from my iphone using an account on that server it doesnt work. this is what i see in syslog: May 15 07:14:52 coax postfix/smtpd[1432]: NOQUEUE: reject: RCPT from mobile-166-137-139-003.mycingular.net[166.137.139.3]: 450 4.1.8 <eppo@customconnexions.com>: Sender address rejected: Domain not found; from=<eppo@customconnexions.com> to=<xxxxxxx@aol.com> proto=ESMTP helo=<[10.25.15.47]>
View 1 Replies View RelatedI'm trying to figure out how to access the local part and the domain part of an email address in postfix's main.cf. For example, myname@mydomain.net has myname as the local part and mydomain.net as the domain part.I get the whole email address with %s. I want to speed up the lookups by writing better database queries.I've had no luck finding this in the otherwise well documented postfix.

I've recently upgraded my home server from fc5 to fc13 which means installing the latest version of postfix (identified as 2.7.0 in the maillog). It is used to send mail from cron jobs and logwatch to a local mailbox (aliased) and my googlemail account so I can monitor when away from home. I finally got it working, but had to pull a trick that I feel bad about--it feels very hacky, and does not survive a reboot.The problem is no matter what I do, this version of Postfix ignores the settings for "masquerade_domains", "myhostname" and "mydomain" in main.cf, using instead whatever 127.0.0.1 (or :::1) is set to in /etc/hosts!!
To send mail to Internet locations, the "from" needs to be a valid domain. In an earlier version of Postfix (2.6.x) I just fudged this to a domain I own (that is parked) in main.cf using "masquerade_domains". Now I have to insert it in /etc/hosts instead of "localhost". I can't find anyone on the web who seems to be having this problem. Postfix is definitely reading main.cf as it is obviously picking up other setings such as debug_peer_level and proxy_interfaces.
As I said, it works, but I don't like my solution and /etc/hosts gets rewritten to ":::1 localhost6.localdomain6" when the system is rebooted, meaning I have to edit it to get Postfix working again as sendmail rejects "localhost6.localdomain6" as not found:

Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only.I had follow this how-to http://www.linuxmail.info/squirrelma...o-in-centos-5/ and complete up to squirrealmail web mail. I added two new user to try on sending and receiving mail. It works.I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, i install VM player on it and run CentOS inside the VM Player.I want to do testing on Windows 7 side by installing Thunderbird email client program, i want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How ?
Do i have to do any other configuration on CentOS ? any DNS ? port number for IMAP,POP3 or SMTP ?
I have a webserver that I run myself utilizing CentOS 5.3. I added a postfix server just to send outgoing mail to people who are part of my webpage. I do not do any email exchange so I can actually receive email on the server, only send (if someone can help me out with that I'm willing to listen).Basically I want to add a disclaimer to the bottom of every email that gets sent out, no matter who sends the email, stating the the email is sent from an unmonitored email account so don't reply to the email. I followed the steps listed here [URL].. even though it was for Fedora 8 it seemed to do what I needed it to do. For some reason no matter who I send email with the disclaimer does not show up. I am doing masquerading so when the email gets send it shows it comes from my domain, not localhost.localdomain because most webservers block it assuming it is spam mail.

View 1 Replies View RelatedI have postfix sort of working correctly. postfix can send email to the internet but it doesn't want to send email to my local exchange server. What I need is for postfix to send emails directed to @xyz.com to my exchange server instead of itself.

www.xyz.com - centos 5.3 server with postfix
www.xyz.com can send emails to my hotmail.com account so that part works correctly. www.xyz.com can't send email to username@xyz.com. postfix seems to be delivering the email to itself and not the exchange server.

Our company is an education training and there are 2 mail servers by used.One is postfix in CentOS,other is WinWebMail in windows2003.
Postfix server has 1 public IP and 1 private IP(192.168.1.224),but WinWebMail only has 1 private IP(192.168.1.253).Bcuz we'll broadcost news of training to students and ourselves,but postfix is cannot do that automaticlly,I guess that that is 2 server are the same domain name in DNS server[URL].The question is Postfix can send all mail but [URL].now I wanna try to used postfix have a routing to WinWebMail server,I mean I add a countant in WinWebMail server,if we wanna send some news to everyone in [URL].The postfix will be tranfor to WinWebMail server,and the WinWebMail broadcost to all of [URL] but now other domain name. how to do that in Postfix server?
I am running CentOS 5.2 on a server here in my home. It runs Dovecot and Postfix and also serves as a website host for a small website of mine. Everything works fine. POP, SMTP, Webmail, WWW, all works great and has for ages.Here's the issue. I recently reinstalled a clean copy of Windows 7 on a workstation in my home onto a new harddrive(I still have the old drive int he machine so I can boot to it as well). I setup the Windows Live Mail client to send/receive mail with my mail/web server. However, it won't connect to the POP server on my server machine.Here's the kicker. If I boot to the old harddrive that is running Windows 7, it connects fine to my mailserver and can send/receive just fine. I've checked, rechecked and rechecked and all mail settings on the mail clients on both drives are identical.
Note: The installations of Windows 7 on both drives is identical. Same computer name/ same credentials, same IP, etc. However, as I stated, I can send/receive email with my server if I boot to my old drive, but if I boot to my new drive, I cannot send/receive.
I configured a Postfix Server to relay the messages to an Exchange Server. To keep it simple I configured all my users locally and I setup local .forward files in their home folders, specifying their local Exchange address.
Everything seemed to work fine (for years now), until I upgraded postfix in October, 23rd 2010.
Alas, lately I noticed that, since then, even if I just realized it now, sometimes the server seems not to use the .forward file and tries to use the local delivery using cyrus, which does not find a local mail folder (obviously, since I never created them as I didn�t want to) and replies to the sender with a "550-Mailbox unknown" error. Today I enabled the "-v" mode for "local" in master.cf the debugging the problem a bit better, to see what's the problem.
If I was sure about the problem being the postfix version (2.3.3, which is way too old now!), I'd give it a try and substitute it with the latest 2.8.2 (even if the server is a production server and is almost untouchable).
Following the error and my main.cf and master.cf setup files:

View 1 Replies View RelatedI have a Bind DNS caching-only server setup that is working. I am bringing up a new AD domain controller that will also be a DNS server for that AD but I don't want it responding to any DNS queries except those that are AD related.So, my goal is to leave this caching server as the primary DNS server for stations on the network and have it forward requests for the AD domain to the domain controller.My understanding is that I just need a forward zone for that domain pointing to the domain controller. However it does not seem to be working.So that leaves me to think that my caching server is not forwarding properly.
For example, this AD is going to have a naming convention of hostname.mydomain.local.If I do an nslookup and specify the domain controller's IP address as the server, I can query addresses that exist in DNS on that server, such as dc1.mydomain.local.However, queries to my caching server times out (I get a response from the caching server if I query mydomain.local but none of the objects in that domain) Here is my named.conf file:
options {
directory "/var/named";
listen-on { 192.168.0.14; 127.0.0.1; };

Things I have tried to fix this problem, but didn't work.

2) Did a complete filesystem relabel with a touch /.autorelabel and reboot.
3) Did a restorecon -F -R on /etc/postfix, /var/spool/postfix and /usr/sbin/post*
Nothing above has worked and have no idea why with selinux disabled postfix works and with it on it fails.
