in the omnifocus instructions:

"Once the Mail Rule has been added, you can tell OmniFocus what kind of messages to look for. One way is to look for messages that have +omnifocus before the @ sign in the destination address, as in cornelius+omnifocus@omnigroup.com. If your mail service is properly set up for this type of addressing, the message arrives in the correct mailbox as if the plus sign and the extra word were not there, but they act as a label for special handling. "

how do you set this up in your mail service?
