Custom-Built Software

The Mailtrust email hosting system has been built with open source software, plus a mix of custom-built software. Below are some of the applications that our development team has built internally.

Webmail

Our webmail client includes incredibly fast message searching, integrated calendaring and shared calendaring, tasks lists, a feed reader, and many other features. Updates to the webmail client are frequent and bring new features and improved usability. Our fully AJAX-enabled webmail client was initially released in the second half of 2006. Prior to that time, we had used a custom implementation of Squirrelmail.

Webmail Mobile

As mobile devices become more powerful and widespread, the need for mobile webmail access has increased. Webmail Mobile is readable even on very small screens and yet is powerful enough to allow users to read and compose email, access IMAP folders, read RSS feeds, and manage their task lists.

Search

Mailtrust has created an advanced search index to allow our customers to quickly locate matching emails. Please read more about searching here.

RSS Aggregator

Really Simple Syndication is a method of publishing news and current information to a large number of recipients without the use of email lists. News sites and blogs are two of the most common uses for RSS. Mailtrust has added RSS aggregator functionality to the webmail client, allowing users to manage many different RSS "feeds" from a single location. Each RSS feed has a separate folder and feed items are displayed like emails. Email administrators have the option to add feeds for their users and make them mandatory, if desired.

BLAgr

BLAgr, short for Blacklist Aggregator, was custom developed at Mailtrust to combine the many spam blacklists into a single set of DNS entries that are kept up to date across several DNS servers. By combining a large number of blacklists, spam filtering software can assess with a single DNS query whether an email comes from a person or server that is blacklisted.

Vault Data Backups

Emails are backed up nightly and stored for 14 days. Read more about the custom solution Mailtrust developed with Amazon's Web Services here.
