Accounting Software

I have multiple email accounts for personal and business use. Is there a good light weight software which I can be used to keep track of all the accounts. I should be able to save all the POP/SMTP settings because in event of crash I don’t want to put all those values again.

ebay). I am new to ebay & this was my 1st purchase. The software came damaged. The seller gave me their email stating if there were any problems let them know. I emailed & emailed them no answer. Finally a friend told me to dispute it through paypal. So I did, nothing happened & they closed the dispute. I gave the seller a bad review stating that they failed to package the software properly. Which they did! So now they gave me a negative feedback as a buyer, but I paid them right away. They want me to withdrawl my negative feed back I want them to give me send me new software but I can’t get in touch with them, because of the negative feedback & they don’t answer emails from their personal account. What can I do?
