Mail Server Compare

Why compare mail servers?

Keep in mind that a mail server is a crucial part of any organization’s information and communication system and, as such, engaging in a thorough mail server comparison is a must in choosing the best mail server. Without the opportunity to compare mail servers, the final choice will most likely be detrimental instead of beneficial to the organization – and that is truly a waste of time, energy and even money considering the substantial investments poured into it.

With that being said, let’s make a mail server comparison among Sendmail, Postfix and MailEnable to determine which one has the superior features and functions.


Sendmail is an MTS for UNIX and similar systems. It is a software application that rose to relative popularity in its market niche by virtue of being one that was supplied as a pre-packaged component of the main product that went with it, not exactly because of its excellent quality. Many Unix, IBM and OS/2 Warp compiled Sendmail, created configuration files, and the packaged it along with their operating systems, thus, its widespread use.

When you compare mail servers, Sendmail has the weakest security system especially when compared with Postfix and MailEnable, no thanks to the design and implementation bugs that keep cropping up even with newer versions. Such non-secure system is worsened by the poor local delivery capability, which is to be expected considering that even MTS proponents asserts that local delivery is not a part of Sendmail’s job.

Why then is Sendmail still popular? Well, because it comes bundled with the operating systems!


If you compare mail servers, then Postfix should be included, too, because it is also a popular mail server. It is a better mail server because it supports most of the current innovations in a modern-day mail server including but not limited to:

• Virtual domains

• SMTP relay

• Consultation of SMTP client on its whitelist, greylist and blacklist databases

• Host and user masquerading

• Delivery to mailboxes with Maildir format

As you compare mail servers, you will observe that Postfix utilises two large monolithic configuration files instead of the multiple task-oriented configuration files. You will then have to learn a single set of configuration file keywords.

In any mail server comparison, the issue of security always comes up for good reason – the mail server will contain sensitive information via emails and messages. Postfix is mostly secure, which means that certain risks of hacks and attacks are still present.

MailEnable –

Many interested customers who compare mail servers will eventually turn to MailEnable. The mail server is increasingly becoming popular because of its excellent features and functions such that its product functionality from the web mail interface to the security system has been the subject of favourable reviews. A few aspects of its product functionality include:

• Use of the Microsoft Management Console (MMC) allows for excellent webmail administration and provisioning

• Unlimited number of users can be on an unlimited number of domains because its licensing is not the per-seat model

• Multi-domain support that allows for multiple mail processing for multiple domains on just one server

• Mobile connectivity

• Scalability and clustering possibilities are ready to be maximized

And because when you compare mail servers you will also compare prices, MailEnable provides its customers with several choices in price – free of the Standard Edition and at reasonable prices for the Professional and Enterprise Editions.
