Delete Email Addresses from a list

Hello. I have a not very large data base of email addresses where I keep adding and deleting addresses. I manage it manually because its the cheapest I cant do. I would have some maybe 3000 email addresses or so.

Problem is, people keep shifting jobs and email accounts, so I get delivery failures.

Is there a way for me to create a list of delivery failure email addresses (I can do this manually) and use AppleScript to delete these email addresses from my master list? Doing this manually takes far too much time...

Re: Delete Email Addresses from a list

Applescript:

(*
This script offer two ways of use.
case 1 : you define a Mail rule moving the rejected messages in a dedicated mailbox (supposed here to be named "aaa")
case 2 : You select a group of mails then run the script.

In both cases you will retrieve the rejected addresses on the desktop in a text file named : "Undelivered_dervilednU.txt"

The behavior is ruled by the setting of the property named usedArule.
*)

(*
use AppleScript version "2.4"
use framework "Foundation"
use scripting additions

set startDate to current application's NSDate's |date|()
*)


property usedArule : true
# true --> execute case 1
# false --> execute case 2

# Use of this script object fasten the treatment of lists
script o
   property theSources : {}
   property theAddresses : {}
end script

set o's theAddresses to {}

tell application "Mail"
   activate
   if usedArule then
       # case 1 : a rule moves the rejected messages in a dedicated box. Here it's assumed to be named "aaa"
       tell mailbox "aaa"
           set o's theSources to source of every message whose reply to starts with "Mail Delivery System"
       end tell # mailbox
       
       repeat with aSource in o's theSources
           my extractAddress(aSource)
       end repeat
   else
       # case 2 : You prefer to select a group of messages and apply the script to the selection
       set theMessages to the selection
       repeat with aMessage in theMessages
           if reply to of aMessage starts with "Mail Delivery System" then
               my extractAddress(source of aMessage)
           end if
       end repeat
   end if
end tell # Mail

# I retrieved a good old efficient script handler so I use it.
set o's theAddresses to my heapsort(o's theAddresses, my cmpasc)
set theAddresses to my recolle(o's theAddresses, linefeed)
set thePath to (path to desktop as text) & "Undelivered_dervilednU.txt"
my writeto(thePath, theAddresses, «class utf8», false)

   display dialog "That took " & (-timeDiff as real) & " seconds."
