Hi :)

I did take a look at the mail headers I was sending by Thunderbird
(Mac Os X 10.4).
Well, when it gives the HELO command to my provider smtp it also add
my mac os x registration data.
I'm not an hacker so maybe i did not understand anything at all but I
did find this header and then I became suspicious... here it is:

Received: from unknown (HELO name-surnames-ibook-g4.local)
([my.external.ip.number]) by outrelay-b11.libero.it with ESMTP; 23 Nov
2007 21:20:34 +0100

I'm not paranoid, it's just a privacy issue.

Thanks in advance for your comment or just a link :)

PS.
Please excuse my basic english

I'm not even sure what the privacy issue is. Do you mean
"name-surnames-ibook-g4.local" above? That's not a Thunderbird thing,
it's part of how SMTP (mail transfer protocol) works. It's going to
fill in whatever you have entered as your computer's name there.

Yes, some mail accounts of mine are not linked with my personal
identity, or for some purposes I don't want to share my first and last
name by networking mail.

Thank you, I forgot that the "name-surnames-ibook-g4.local" was my
computer name :)
