Thread starter hockey97 Start date Aug 13, Hi, I want to setup a mail server mainy postfix with mysql.

I want to make my own php webmail interface to my website. I also want to use php to use the mail function to use these accounts too See section 4. Additionally, Postfix can be built to support dynamic loading of Postfix database clients database plugins with the Debian-style dynamicmaps feature.

Postfix 3. Dynamic loading is useful when you distribute or install pre-compiled Postfix packages. This implicitly enables dynamically-linked library support, installs the configuration file dynamicmaps. Database plugins are named postfix- type. With Postfix 3. Failure to follow this advice will defeat the purpose of dynamic database client loading. Every Postfix executable file will have database library dependencies.

And that was exactly what dynamic database client loading was meant to avoid. See the next section for how to customize the location and version of Postfix database plugins and the location of the file dynamicmaps. As a reminder, the directories with Postfix dynamically-linked libraries or database plugins should contain only Postfix-related files.

Linking these files into other programs is not supported. To override the default location of Postfix dynamically-linked libraries and database plugins specify, for example:. This produces inconsistent results with different versions of the make 1 command. To append the Postfix release version to the pathname if you intend to upgrade Postfix without stopping the mail system:.

To override the default location at compile time specify, for example:. For backwards compatibility with Postfix 2. The configuration file dynamicmaps. Thanks to this, you can install or deinstall a database plugin package without having to edit postfix-files or dynamicmaps.

Instead, you give that plugin its own configuration files under dynamicmaps. Each configuration file under the directory dynamicmaps. Each configuration file under the directory postfix-files.

All Postfix configuration parameters can be changed by editing a Postfix configuration file, except for one: the parameter that specifies the location of Postfix configuration files. Parameters whose defaults can be specified in this way are listed below. The number of connections that Postfix can manage simultaneously is limited by the number of processes that it can run.

This number in turn is limited by the number of files and sockets that a single process can open. For example, the Postfix queue manager has a separate connection to each delivery process, and the anvil 8 server has one connection per smtpd 8 process. Postfix version 2. Warning: the above has no effect on some Linux versions.

Beware, undocumented interfaces can change at any time and without warning. But wait, there is more: none of this will work unless the operating system is configured to handle thousands of connections. If the command produces compiler error messages, it may be time to search the web or to ask the postfix-users postfix.

Each system type that Postfix knows is identified by a unique name. You must use a name that includes at least the major version of the operating system such as SUNOS4 or LINUX2 , so that different releases of the same system can be supported without confusion. Add a case statement to the "makedefs" shell script in the source code top-level directory that recognizes the new system reliably, and that emits the right system-specific information.

You may have to invent new feature macro names. You're likely to end up placing " ifdef" sections all over the source code again. This text describes how to install Postfix from source code. In this case you should try to "flip" the switch to "Postfix" before installing Postfix.

Do this by passing the -Snorecord option. Send the email by piping a string to the s-nail command. Adjust the command to mark your Linux user as the recipient:. As a final test, check whether s-nail is able to correctly send email messages. To do this, you can pipe the contents of a text file into the s-nail process, like you did with the init message you sent in the previous step. Then, use the cat command to pipe the message to the s-nail process.

You can do so with the following example, which uses these options:. Also, be sure to change user email. Then, navigate to the inbox for the email address to which you sent the message. You will see your message waiting there almost immediately. You can view your sent messages within your s-nail client. Start the interactive client again:. You now have Postfix configured on your Ubuntu Managing email servers can be a tough task for new system administrators, but with this configuration, you should have enough MTA email functionality to get yourself started.

This user is to be named 'postfix' and have a unique user and group id, with a non-existent shell so that nobody can login to the account for security reasons , the account does not require to have an existing home directory either.

After you add the user that the mail daemon will run as, it is a good idea to forward all that user's email to root. We do this because nobody can login as the user postfix, so it is a good idea to forward any email it gets to root.

If you want to protect the maildrop directory, read the following section. Protecting your Maildrop directory By default, postfix installs with a world-writable, mode , sticky maildrop so that local users can submit mail. Well this method avoids using set-[gu]id software, it is usually a bad idea if you have some annoying lusers.
