How to check email header

This is essential for all. When someone is asking you to check email header? Or the sender? The most common mistake is looking the email itself and provides you with the screenshot of the sender, the recipient, the subject, date and time.

This not the email header and they should look like this;

The header provides you with details of the email received. This is useful when if possible to find out  the real sender, for example, you have received a spoofed email or blacklist an email server from sending you spam emails.

Today, we are going to show you do it with Outlook, Thunderbird and SmarterMail webmail. It is easy for Thunderbird and SmarterMail webmail users. There are more steps and complicated for some to get this option.

We show you on how for Thunderbird email application; Just go to the email, under more to view the source.

SmarterMail has the view header option in Webmail too. Go to that email, more option is the icon with 3 dots, then view header.

smartermail

It is a bit more steps for Outlook. But you only do it once to get this option permanently. Follows these steps. You need to go option from your file tab, add the message option to one of the new tabs. Once it is added, the message option will be permanently available for all emails.

IDS in email server?

ids in smartermailI have dealt with web hosting for many years now. SmarterMail is the only email server software comes with IDS. In case you didn’t know what is IDS? IDS is normally found in firewall known as intrusion detecting system. IDS has a set of rules if any connection has violated the rules, mitigation will kick in. The serve to minimize the risk of a server’s attack or hack.

SmarterMail as this to stop abnormal activities, like attempting to log in with failed passwords known as brute-force or similar. This has greatly reduced a compromised email account or server’s abuse. Base on my experience, SmarterMail email server has very low a compromised email account uses to send spam emails. Thanks to the IDS in SmarterMail.

Email servers are they different?

VIEW MAIL SMARTERMAILToday, 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.

SmarterMail 14.x is here

I urge all smartermail users to upgrade their current SmarterMail server to Version 14.0.5637. One of the significant improvement is the the newly compiled ClamAV 64bit which is more efficient and lower system overhead to replace the outdated and less efficient 32bit ClamAV.

 

Version 14.0.5637 (2015-06-08)

Key Features
  • A temporary address can now be generated by users with a short life span that operates as an alias to their account. This is to allow sign ups to external services without giving out the account’s real email address.
  • Message Sniffer is now available as an antispam add-on.
  • Multiple calendars can now be added to a single account.
  • Option to mark a domain as external and have messages to that domain sent either to the domain’s MX record or to a specified host address.
  • System administrators can now add customized HTML and change the login header text through settings on the General Settings page. They may also allow domain administrators to override these customizations.
  • Deleting email folders in either an email client or webmail will now have their associated folder on disk removed as well. Orphaned folders from earlier releases of SmarterMail will be cleaned up automatically.

  • Changed: Content filtering now decodes base64 and quoted-printable encoded text parts in email messages before applying filters.
  • Changed: Improved the ClamAV definitions update process, including 64 bit support and ClamSup.
  • Changed: Migrating the same Google calendar twice will now overwrite the previously migrated events instead of creating duplicates.
  • Changed: Time zone information now utilizes the built-in system registry time zone information instead of an external file.
  • Efficiency: Deleting a large number of items from the IP blacklist or whitelist is now much faster.
  • Efficiency: The load time of the monthly calendar view is now much faster.
  • Fixed: A recipient address formatted with a quoted username containing a certain sequence of characters will no longer cause high CPU during the SMTP session.
  • Fixed: Changed how recurring calendars with a recurrence count of zero are transmitted via Exchange Web Services to work around an error when syncing with emClient.
  • Fixed: Gmail email migration now functions correctly when one or more Gmail labels contain characters that are not allowed in Window’s folder names.
