Tor and Thunderbird: Outgoing Email Unsafe?

[Job]

Tanks Mike for your fast and helpful replies

I am not that worried about traces of activities left on my computer. I 
just want to be sure receivers of email wont be able t see my IP and stuff.
So if i use a web based email and use firefox with Tor to access it with 
my normal settings(the settings that I always use when i use the 
Internet) so not a totally separate profile.The receiver still wont be 
able to trace me right? I understand that for complete security I should 
make a new browser profile so the cookies wont mix. but as cookies are 
on my own computer they have nothing to do with any info the receiver of 
email might be able to get from the header or whatever of the email i 
sent, am i correct?

Some web based email services,like mail.com if i am not mistaken, give 
you the option to download a little prog that warns you when a new 
emailis in.
Does this affect my anonymity? I suppose it does as the server from 
mail.com will connect to my comp to tell me there is a new message. On 
the other hand, if I use tor enabled firefox wouldn't that connection 
also be anonymous?

last question: Why cant I access the account without Tor?(safety wise i 
mean). As long as i dont send any emails to anyone isnt it safe? I 
understand my ISP and mail.com will be able to trace me but not 
receivers of emails as I am not sending any at that moment.
