Outbound Infrastructure Upgrades

Our outbound email infrastructure has been significantly upgraded. We have doubled capacity, created workflow to increase capacity further at a rapid pace, and added a second IP range to increase diversity.

We have obtained a new IP range that is of the cleanest reputation, and deployed new outbound relays in Dallas under this new IP range.

We hope to see this improve the quality of email delivery, specifically as it relates to landing in inboxes (where we can influence this).

Auto application of credit

By request, credit existing on an account will now be used to pay any open invoice automatically.

Eagle Migration - what you need to know

The Eagle server is in the process of being migrated to new hardware, to address sudden disk performance issues. As a customer on the Eagle server (you know if this is you), here are the things you should expect:

  1. The final event cannot be scheduled, doing so would mean a loss of data for customers (dynamic usage + rsync + network + iowait = not possible to calculate accurately, can only schedule if we accept data loss).
  2. The SSL certificate will briefly return invalid, causing errors in email clients. This will clear up in under 3 minutes.
  3. You may see emails that you have recently deleted appear again.
  4. You may see a few duplicated emails.
  5. You will absolutely see errors when this happens, in the range upwards of 5 minutes.

Note that many customers are seeing errors as a result of the performance issues, therefore the migration is expected to appear as little more than another brief moment of performance loss to the end user. Given that this is currently standard, inflicting it without a given schedule is something we consider tolerable given that it will be immediately followed by the end of the errors caused by performance issues.

We will alert again when complete.

Crossbox Test Phase 2

Crossbox has been set up again for a second testing phase, this time without branding. The new server hostname will not be published in public documentation, for the sake of branding removal. You can find your way to it by visiting the previous URL. The rest of the information in the previous update is still good:


This will currently function for ALL cPanel based servers (everything but our old VestaCP servers), including Eagle which had been left out of the first phase.

Planned outage for Crossbox

The mail.mxroute.com installation of Crossbox will be disabled today for some additional work. As this is still in a testing phase and not yet a marketed product, there will be no extra notice.

Central host for Webmail, SMTP, IMAP, POP3

With the help of Crossbox, we now have a central server for webmail, SMTP, IMAP, and POP3. Currently, this is in what is considered a testing phase which means:

  • Welcome emails will still contain the same information
  • No documentation will be updated
  • No links will be updated

A couple key things to note as well:

  • This is only for our cPanel servers
  • It has currently been rolled out for all but Eagle server

You can find this server here: https://mail.mxroute.com

On the mail.mxroute.com host, you can find these ports open for services:

IMAP: 143

SMTP: 587

POP3: 110
POP3 SSL: 995

New Slack community for support

We're replacing Discord with Slack, in an effort to better choose our tools for each job in front of us.

Invitation can be found on our help page: https://mxroute.com/help.html

External relay server added

Added relay server outside of our current network / IP space as a failsafe in the event of an outage.

Additional filter server added

Added a new filter server for network diversity, to better ensure uptime of outbound infrastructure.

Support Beacon

Support Beacon added to website and customer portal (WHMCS). This is the blue icon at the bottom right, allowing you quick access to Knowledgebase and Support contact.
