It's why it's often say to never open spam-mail to avoid this. Sometime I open them (without load any remote content) to see the progression of spammers. If you want to check if it spam or not look at the source of the mail (Ctrl u) and copy an URL like this to a text-application like notepad, mousepad ... : http://someurl.example/blahbfbqsldbqshdkdjzecjg2654135416 Remove all strings after / and if it spam often there's nothing on : http://someurl.example/ http or https. In this case https is not a protection. The "blahbfbqsldbqshdkdjzecjg2654135416" is a key to match your mail adress and the program say "yes sold this real mail send it more and more spam!" and after it load an image or other remote content (CSS, ...). -- Stéphane Sorry for possible mistakes in English! _______________________________________________ support-seamonkey mailing list [email protected] https://lists.mozilla.org/listinfo/support-seamonkey
