I have two email addresses

[Alex Santos 10MB Pakiet Mail]

Hi, I have two email address, could you just let your server know in 
case I accidentally use the wrong one?

The first email (The one I subscribed to the list with is, 
misiewicz at poczta.tp.pl, and the second email address is 
izabella.misiewicz at neostrada.pl)

The reason I am asking you to allow this is that both these accounts 
are setup in my MAIL app in OSX. I may not remember that I am 
subscribed as misiewicz at poczta.tp.pl, should I use the other mailbox to 
send emails they may bounce back and I may have to keep resending them 
or may even not notice that they bounced back.

If you could add this somehow, it would save me potential grief. If 
not, then I must be more careful.

Your consideration is appreciated.
