thunderbird-10.0.3-1.el6_2.x86_64 on Scientific Linux 6.1
and if I send an e-mail (with Gmail) from my Thunderbird then I can see that the e-mail I sent contains a very-very bad thing:
Received: from [192.168.1.142] (31-149-121-34.pool.myisp.com. [184.108.40.206])
So ALL the e-mail that I'm sending containst my NATed IP address + my public IP address.
Can I delete/remove these lines, so that they will be aren't in ALL the e-mails that I send??
UPDATE: if I send an e-mail with the gmail web interface, then:
Received: by 10.112.129.10 with HTTP; Sat, 14 Apr 2012 09:20:13 -0700 (PDT)
Aren't there any Thunderbird Add-ons that modifies my IP Address in the e-mail?
