it is possible for forward those emails from one to the other, but im not certain it will work indefinately or once the account is closed. You go into preferences on both accounts, and give the details of each account... one as sender or forwarder, the other as receiver. it's somethig to do with the PoPs i'm sure, so hopefully someone who is beter qualified with PoPs will answer and fill in the blanks for you. I do beleive under the preferences menu, the follow through is quite simple. Good luck.

the technique relies upon on which digital mail provider you're utilising. For gmail u can say delete this account on your google money owed settings. while in different mailing centers in case you give up utilising your digital mail id for 3 months (varies from provider to provider) than it gets deactivated immediately. in case you utilising a domestically owned digital mail server than you may ask the server admin to get rid of your id from the database.
