Often senders of span emails ("spammers") find out about your email address on public discussion forums, mailing lists, etc.
When you need to leave your email address for a time-limited purpose (ex. you wait for a reply to be sent shortly to you via email), avoid giving away your real email address!
With DeskNow you can give an email address that is valid only for a limited period of time. So even if it ends up in the hands of spammers, it won't compromise your mail address forever.
To use a time limited email address, simply append the date when you give your address to someone.
Example: if your email address is joe@company1.com (running the DeskNow mail server), and you want to leave your email on a public forum using an address that expires the 18th of January 2004, simply leave the address joe.040118@company1.com .
You do not need to do anything particular in DeskNow! When the DeskNow mail server receives an email for joe.040118@company1.com, it will deliver it to your real email address (joe@company1.com) only if the current date is before or on the 18th of January 2004. Otherwise, it will reject it. You can give out as many time limited email addresses as you want, with the same or different expiration dates.
Remember the rule: username.YYMMDD@domain.com
Note: time-limited email addresses are effective against automatic robots that scan the web for email addresses. A human could probably recognize the trick and circumvent it. However, most spammers use automatic robots to collect addresses.
