I'm still workingout a little bug in my idea, but that's because I'm using Thunderbird and haveto get used to how its setup.
Anyway, a person hasto begin with the postmaster addresses off every known email program. Oneis Google whose postmaster addy is :
Steps are these :
1-send an email butbe sure it has a fake username, one that'll ensure the postmaster will send itback to you saying "no such account" or whatever. Do this fromevery email domain account you have (point is here to get a list of all of them,the major ones anyway).
2-notice the text ofan undeliverable email sent back to you? Well just delete off things likeany header info and the line where it has listed the email address you justtried to email. But save the rest of it - the general text is what you wantsaved for future use (see below).
3-now you have thispostmaster email address list, save it aisde for later.
4-using Thunderbirdor similar program (the email program has to allow you to put in a fake"from" address for sending emails out), set up a filer in Thunderbird(or whatever you're using). This filter will serve the followingpurpose :
When an email is forwarded to the email program and account you've setup withsay, the "firstname.lastname@example.org" account in Thunderbird, thefilter has been instructed to "reply with template" to all emailreceived at this account. When anyone sends you an email, it'll forwardto Thunderbirds filter which will then spit out the autoreply (a "replywith template") which will be addressed "from : email@example.com". So the sender gets this email from "the google postmasters address"and will get fooled by it into thinking the email address he just sent an emailto is DEAD. And btw, when the sender of the email gets it back (orso he thinks it came back to him undeliverable ), it'll inlcudethe text you saved from an actual postmaster email you got (this is for authenticity) saying "email to the receipient has permanently failed"or whatever (this text would've been pasted in for the "reply with template", which will get emailed everytime someone send you an email andyou do this part while setting this up).
Unless someone issmart enough to check the header of the emailed reply they just got from thepostmaster, they'll just think the email address they just tried to send to isDEAD. And for those who wouldthink and check the header, they'll still not be able to send an email throughsuccessfully since they'll keep getting the "postmaster" oneinstead... very annoying and good to use to annoy someone.
Of course, to dothis you must make a filter in your email program (not Thunderbirds) telling itthat email from this person or on this subject is to get "forwarded"to another account you have setup in Thunderbird - reason is you'll need to doit this way unless you dont mind all email send to your addy get a postmasterreply. This way, only select emails sent to you are filtered andsent to the Thunderbird program email account you have waiting.
The reply text theyget will look pretty authentic, like this :
This is anautomatically generated Delivery Status Notification
Delivery to therecipient failed permanently.
Technical details ofpermanent failure:
Google tried todeliver your message, but it was rejected by the recipient domain. We recommendcontacting the other email provider for further information about the cause ofthis error. The error that the other server returned was: 550 550 5.1.1 Not ourCustomer (state 14).
Hopefully Iexplained what I was thinking.. :?
