After searching what has been growing I found this in /home/gcecchi/.thunderbird/pe1wv5qu.default/ImapMail/myimapaccount # ll INBOX -rw------- 1 gcecchi gcecchi 22878721204 2009-12-14 16:40 INBOX almost 23Gb!!!!!! This is an imap account against an Exchange 2007 server. In inbox I have less than 1000 messages where less than 10 are more than 1Mb in size...... So I'm questioning fron where this big size arrives..... More strangely, I have a mail with 11Mb of size in INBOX. I delete it and suddenly INBOX size increases of about 14.7Mb!!!! And in the mean time I have received no mail at all.... # ll INBOX -rw------- 1 gcecchi gcecchi 22894180950 2009-12-14 16:43 INBOX Any hint on thunderbird 3 settings? Thanks, Gianluca </blockquote><div> This is a good example on how a bad default can "kill" an application. Go to preferences -> advanced and UNcheck Enable global search and indexer. Also, for each account UNcheck "Keep messages for this account on this computer" Then, you can delete the remaining files in ~/.mozilla/firefox/..... or better, delete the whole firefox directory, and re add your accounts, one by one. </div></div>In my case, thunderbird downloaded and indexed all my gmail messages. Almost 4GB of junk that was intended to stay on gmail only. Why a developer chooses so bad defaults is a mystery to me.... -- Paulo Roma Cavalcanti LCG - UFRJ
