Today, I’m going to share a bit on the common type of email servers in the web hosting market and integrated into the web control panel. Most of us email and why should I know which type of email server is used. Aren’t they are the same. Actually, you are almost correct but how they have served and behaviour will affect the incoming and outgoing emails, and likely your mailbox too.
There are 4 common types of email servers; Exim in cPanel, Postfix in Plesk, Mailenable and Smartermail. All are free except SmarterMail if you are creating the No.11 mailbox you need to buy a license. Exim and Postfix are free and they are the popular choice in the Linux world. However, these known as MTA they are limited to SMTP, unlike Mailenable and SmarterMail, the email servers will take care of all protocols.
In fact, they all can rate limit the speed of connecting and sending emails. Exim is more flexible than Postfix, the more it is flexible, similarly, it will be more complex. To an end user, it will not make a difference unless you are administrating the mail server. These two MTA are Linux based, thus the commands are shell command line, while Mailenable and SmarterMail are Windows-based, you do not use the more complex PowerShell command, most things can be done from the server’s interface.
So far, only SmaterMail and Mailenable have their own webmail, Postfix is used by Plesk and Exim is used by cPanel, they use the free ones and opensource webmail like horde. The free webmails look boring. In your 1st glance, you are not likely to continue with webmail but maybe an Outlook or ThunderBird.
However, it is a big difference if you are using SmarterMail. The webmail is intuitive. The anti-spam and anti-virus come default can screen emails with the desired value of each RBL and many more. Even a non-technical savvy person will not take much time and set up those functions. In addition, the IDS protection is something you cannot find in any of those email servers.
I personally found the reports are useful in SmarterMail. There are usage statistic for mailboxes and domain, the type of traffic, the number of spam emails was received etc. These are especially good to pinpoint areas and downgrade or upgrade email server.
Despite that those MTA I have mentioned serve the purpose connecting people and send emails. If you drill down deeper, you can find actually email server by SmarterMail can do more and let you see better, Yes, SmarterMail is a paid software unless it is for 10 and below mailbox which is free, but I will opt or SmarterMail for the business collaboration tools, enhanced email functions and protections. In a way, it helps in email delivery, communication and administration, saved you a lot of money and time.
