Suffix support provides the power of multiple email addresses with one mailbox account.


How it works

Suffix support means that in addition to “ address@” you can also receive mail at “ address+extrastuff@. ” The text after the “+” is controlled by you.

Real-world examples. Customer uses johndoe@xmission.com and subscribes to a number of mailing lists and has transactions with a wide range of contacts. Using suffix support customers can easily identify and filter messages.

Here are some user example addresses: johndoe+wikipedia@xmission.com - johndoe+listname@xmission.com - johndoe+bills@xmission.com

All variants of this address land in your Inbox or are easily filtered to specific folders. Filtering instructions can be found in this wiki or inside the help menu of your mail application.

We can use Flynn as another example. Flynn has @xmlocal.com email domain with Zimbra email hosting at XMission and suffix support works the same way: flynn+purchasing@xmlocal.com flynn+adminlist@xmlocal.com


Track spam

Sometimes you may not trust the website or email list you are providing email address to. Suffix support allows you to protect yourself from spam and track reliability.

In these cases it is common to use the mailing list or website name: user+listname@xmission.com

Note: This works for traditional @xmission.com mail accounts as well as our Zimbra Personal Premium @xmission.com accounts, and all hosted Zimbra business email accounts.


Preventing fraud

Take your online security a step further and add extra protections to your login process with large online retailers such as Amazon and others.

There is a reason online retailer are constantly trying to get you to sign up for Two-factor Authentication with your account on their systems. Fraud. These days all retailers and service providers suffer a constant barrage of malicious attacks where bad actors are trying to access your account to their benefit. The good news, using suffix support adds one more layer of security. This way when a bad actor is trying to social engineer your well known email address with a retailer and they talk to the support rep and are trying to authenticate username/email, they get it wrong because you utilized suffix support for your login. Example, rather than using johndoe@xmission.com you might use johndoe+buystuff@xmission.com. So no matter what, they will not guess your login details. Note, always use a suffix that is not the vendor name. So with Amazon we would suggest never using johndoe+amazon@xmission.com as that is a little too obvious.

So keep yourself safe, use suffix support to manage your online security and communication needs. Also take advantage of vendor provided items such as Two-factor Authentication and we strongly suggest use of password managers such as BitWarden, LastPass, and others.


If you want a deeper dive into this technology behind suffix support it is called Variable Envelope Return Path (VERP). http://en.wikipedia.org/wiki/Variable_envelope_return_path
