In gmail I can set my picture. When somebody receives mail from this gmail account, my picture is shown next to the gmail address. But now I created a mail account for my website. When I send mail from it (using the Mozilla Thunderbird mail client), I'd like my picture next to my mail address just as when sending from gmail. Now I just get this anonymous blue man... Does any mail client support this? I tried googling "mail client picture" and related terms but I'm not finding anything useful.
