![]() Now we can create a database and a user which is allowed to access it: #mysqladmin -u root password 'enter-your-good-new-password -here' It is strongly recommended that you set a password for the mysql root user (which is NOT the same as the "normal" root user) with the command: Vpopmail package uses mysql backend, so we need mysql-server Open your terminal and add debian repository in your sources.list:Īnd then you can update and install the package: # dpkg -force-depends -purge exim4 exim4-base exim4-config exim4-daemon-light You need to remove the exim4 mail server from your machine because by default debian will install exim4 mail server in your machine for this you need to follow these commands Important Note:- Current qmail version works only with vpopmail-mysql package available This can facilitate any further enhancements of anti-SPAM features. These goals are achieved by enquiring the existing vpopmail archives (each format is supported: cdb, MySQL, LDAP, etc.) by using standard vpopmail calls, or using customized chkuser routines.Ĭhkuser 2.0 has detailed logging of accepted and refused recipients and senders, thus allowing a deeper analysis of "who's sending to whom". Qmail-smtpd patched with chkuser may check the existence of e-mail recipients immediately in the SMTP acceptance phase of a message and rejects instantly all the messages sent to unexisting users, thus avoiding additional traffic, backscatter, workload and messages bounced more times. So, if the message is delivered to a non-existant recipient a lot of additional system work and network traffic is generated, with several expensive bouncing if the sender is a fake.Ĭhkuser has been developed with the goal to improve the acceptance SMTP phase of qmail-smtpd. ![]() The original qmail-smtpd program accepts by all messages, checking later for the existence of the recipients. If the check fails, the server closes the SMTP conversation before receiving the mail. The qmail-dnsbl patch lets the client authenticate (using any method implemented), and then decides to perform the DNSBL check looking at the authentication status before the DATA SMTP command is performed. Qmail-queue-custom-error.patch (for simscan) The above Debian Package contains the following patches We are going to install qmail packages available for debian users from The serialmail package was designed to make qmail more compatible with poorly-connected systems. qmail was designed for well-connected systems, so you probably don't want to try to use it for a mailing list server on a 28.8k dial-up. Without one, qmail can only send to remote systems configured in its smtproutes config file.Īdequate network connectivity. Most flavors of UNIX are acceptable.Īccess to a domain name server (DNS) is highly recommended. Large servers may need a couple gigabytes.Ī compatible operating system. Small single-user systems only need a couple megabytes. ![]() See syncdir in the Related Packages appendix for more information. Bruce Guenter's syncdir library can be used to work around this problem. Most modern local filesystems meet these requirements with one important exception: the link() system call is often asynchronous-meaning that the results of the link() operation might not have been written to disk when the link() call returns. qmail's reliability guarantee requires that the queue reside on a filesystem with traditional BSD FFS semantics. The build directions will show you how to tell if you've got the necessary parts.Ī few megabytes for the binaries, documentation, and configuration files.Ī safe filesystem for the queue. After the build, you can free all but 4 megabytes by removing the object files.Ī complete, functioning C development system including a compiler, system header files, and libraries. Qmail will install and run on most UNIX and UNIX-like systems, but there are few requirements:Ībout 10 megabytes of free space in the build area during the build. ![]() qmail uses the Simple Mail Transfer Protocol (SMTP) to exchange messages with MTA's on other systems. It's a drop-in replacement for the Sendmail system provided with UNIX operating systems. Qmail is an Internet Mail Transfer Agent (MTA) for UNIX-like operating systems.
