Hi,<br />
<br />
Thanks, this is not bad but I am actually satisfied with the setup. I am only looking for something that can send me a report if the queue gets bigger then x messages.<br />

Hi,<br />
<br />
I have encountered an issue where my Postfix was compromised or better misused. It resulted in having many thousands of messages in my mail queue waiting to be send. It took me 2 days to notice it.<br />
So I wonder if any of you know if a good and reliable script or tool that can warn me if the queue grows fast or goes over a specified number of mails. Maybe also if the emails send per minute or hour goes over a specified rate so that i can see if something needs attention.<br />
<br />
The attack I had now was that someone managed to upload a php script using magento shop that is installed on my server and then used this to send 50k messages. It actually managed to send more than 30K before I noticed.<br />
<br />
Any advice and suggestions on usable scripts or software is very welcome.<br />
<br />
Best wishes,<br />

Postfix mail queue monitoring

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

The Linux operating system, in all its flavors, has its own share of security flaws that allow intrusions, but there are various mechanisms by which these flaws can be removed, generally divided into two parts: authentication and access control. Authentication is responsible for ensuring that a user requesting access to the system is really the user with the account, while access control is responsible for controlling which resources each account has access to and what kind of access is permitted.
