[ale] Thuderbird qustio

[Chris Fowler]

I've just installed Thunderbird to try it over Evolution.  Evolution is 
a memory hog. 

Evolution has an option to check each folder for messages.  I do not see 
this option in TB.  I use procmail on the server to sort my mail.  I 
have nio rules in the mail client so it is critical that my client check 
each and every folder every 5 minutes.  Does TB do this or can it be 
turned on in the advance configuration editor.
