CentOS 5 :: Postfix Not Sending Email To Right Server?

Jul 23, 2009

I 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.

My setup
mail.xyz.com - exchange 2003 server
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.

How can I tell postfix to send the @xyz.com emails to my exchange server?

Here is a sample of my /var/log/maillog
Jul 22 15:43:43 list postfix/smtpd[9802]: D63168604A3: client=localhost.localdomain[127.0.0.1]
Jul 22 15:43:53 list postfix/cleanup[9805]: D63168604A3: message-id=<20090722204343.D63168604A3@www.xyz.com>

[Code].....

CentOS 5 Server :: Postfix No Longer Sending Mail?

Jan 7, 2010

One of my mailservers running postfix has suddenly stopped sending mail and has been generating the following errors:

Jan 7 12:03:08 postfix/sendmail[3560]: warning: premature end-of-input on /usr/sbin/postdrop -r while reading input attribute name
Jan 7 12:03:08 postfix/sendmail[3560]: fatal: root(0): unable to execute /usr/sbin/postdrop -r: Success

[Code].....

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

1) Stopped postfix, uninstalled and reinstalled.

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.

Server :: Postfix As Sending MTA For Multiple Domains?

Jun 7, 2010

I am setting up a Postfix MTA that will be only sending mail for 10 different domains. We have other servers that will be receiving the mail for the domains so I only need to set up for sending on Postfix.

What my issue is I am trying to configure Postfix so that when it sends mail the header shows what domain the mail came from and not the domain the Postfix server is set to. For example....

[URL]

When I send mail from domain2.com I want it to show in the header it was sent from domain2.com and not from domain1.com. What do I need to set in postfix so that this happens? Right now no matter what domain the mail is from the header always shows the server domain and I can't have that.

Server :: Postfix: Sending Mail From Multiple Domains?

Jul 20, 2009

I'm running a server with two sites which both need to be able to send emails. Currently I have Postfix set up to send email via Google Apps. This works fine, but Google's servers ignore the From: address I specify and substitute the one I logged in with. Is there a way to make Postfix log into Google Apps with a different username based on what site the email is coming from? The server does not recieve any mail itself; Google recieves it and we have it set to forward it to the appropriate person's real email address. I'm only worried about sending mail.

(Postfix is not a requirement here, so if there's another mailer that can do this better, I'm open to ideas. However, sending email directly from the server isn't an option as it's a residential IP address and blocked by most of the big email providers.)

Server :: Sending Email From Mobile Phones?

Mar 23, 2011

So I have Postfix working great and I've always used webmail if I needed to send email from PC's outside of $mynetworks. So fast forward to today where I got my 1st Android powered mobile phone and I can configure the Android mail client to send/receive IMAP email but my question is do I need to become an open relay to allow my random wireless providers dynamic range of IP's to send mail via Postfix? Seems extremely vulnerable and scary to think I would have to allow my providers IP range to relay mail via my MTA. I started reading a bit and I think I need SASL authentication and since both Postfix 2.8.1 & Dovecot 2.0.11 are both configured / using TLS, is there anything else I would need or you recommend for sending email from my Android powered mobile?

Fedora :: F10 - Evolution Stopped Sending Email To Exchange Server

Jan 7, 2009

I am working happily with Fedora 8, evolution chatting happily to exchange 2003, calendar sync the works...impressed. This continued through Fedora 9 (though a little bumpy as all odd numbered Fedora releases are). On to Fedora 10, yes works a treat out of the box (DVD). A couple of updates to evolution later, through yumex (fedora updates), and evolution has stopped sending email to the exchange server. It's also touch and go whether I can read email using OWA.

On pressing 'Send/Receive' evolution pops the error,
Error while performing operation.
Exchange transport can only be used with Exchange mail source.
How could I back out these evolution updates?

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

Server :: Postfix Sasl - Can't Email To Clients

May 13, 2010

I have an issue where postfix is setup to use dovecot auth and as far as I know it works, if i login using telnet to the mail server i can authorize myself y providing the base64 encoded user & password. so if i can login, why cant my email clients. have tried thunderbird and evolution. this is the mail.log relavant entries for sucessful login via telnet

[Code]...

Login by pop or imap works flawlessly that what i dont get. From what i see it SHOULD be working. It it changes things, im using postfixadmin, postfix, dovecot. passwords and info stored in mysql tables. passwords are md5 encrypted. I thought that may be the issue, but that dosnt make sence.

Server :: Email Content Filter Rules For Either Postfix

Feb 3, 2010

I want a mail server that can work just like MDaemon. The reason is, I want to have an email content filter rule that does some thing like this.

1. If the To Header contains "support@thisdomain" then run a program.
What this means is that, there is a program here in the office, and if some one sends an email to the support address, with an attachment of .exe and that person is a customer, then the program should be run. The only thing I need here is if there is a rule or script that can filter email header and run a program.

2. If the Exit Code from a previous 'Run program' rule is in the range of 1 to 100 and if the To Header contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...>
and delete this message.

3. If the EXIT CODE from a previous 'Run program' rule is =0 and if the TO HEADER contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...>
and delete this message.
