Server :: Get Postfix To Deliver Valid Emails To Maildir And Relay Remaining?

Jan 20, 2010

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.

Server :: Postfix To Deliver Local Relay

May 25, 2010

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?

Ubuntu Servers :: Setup Postfix To Relay Email It Cannot Deliver Locally?

Jul 17, 2011

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.

Ubuntu Servers :: Postfix Relay - Exchange Sends The Mail Instead Giving Recipient Mail A Valid Reverse DNS Lookup

Jan 12, 2011

The scenario: We have an external server that runs HTTP/DB servers for out shop system. Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010. The shop system on the external server needs to send mails to customers (order confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.

Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address. My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly. So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts. This is what i get in the mail.log: The successfully relayed mail sent by the shop system:

Server :: Can't Get Postfix Mail Boxes From /var/mail To ~/Maildir?

May 31, 2010

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.

Server :: Setting Up Postfix As Outgoign Mail Relay For Several Domains / Hosts

Oct 6, 2009

I would like to setup postfix to act as a relay for the outgoing mails of a couple of servers each serving it's own domain.The mails we are talking about are standard administrative emails like user registration, password reset request. The volume of those mails will naturally grow as the site grows. Which for me poses the problem that depending on the growth of the site you will sooner or later hit the quotas imposed by (my otherwise preferred) providers like GMail or smtp.com.

So what I need is a mail relay that will only accept mails from authenticated clients from hosts in its access list and relay their mail without restrictions. Is that possible with postfix? What has to be changed in the config and what are the pitfalls?

Ubuntu Servers :: Emails Taking Unusually Long To Deliver (1-5min)

I realize that this is most likely due to a misconfiguration with how my email has been set up.

Server :: POSTFIX Server New Domain Emails Stuck In Queue

Apr 20, 2010

I am newbie to postfix. I added a new domain to my postfix server in the main.cf under mydestinations variable and the relay_domains file. Also, added this domain to my backend exchange server. When I send a test message from the new domain, my messages from that domain appear to be stuck in the "queue active". What does it mean when you are stuck in this queue? Does this mean that my backend email server (exchange 2003) isn't allowing messages from this new domain OR that the POSTFIX server still needs configuring.

Server :: Replacement Postfix - Getting Intermittant Loss Of Sent Emails

Mar 10, 2011

I'm building a replacement postfix email server and I'm getting intermittant loss of sent emails; where: sometimes mail ends up at the recipient (a hotmail address) and sometimes not. Having an offsite relay (or posting directly to the internet) doesnt help either. (Although using hotmail itself as a relay always works despite logged complaints about unchecked ssl certs) Most dissapointingly the log files for the smtp transations are the same for successfully received emails as for the "lost" emails.
