Thunderbird: Using Images in Signature

24. August, 2017

lifewire has an excellent article how to put an image into mail signatures: “Automatically Use a Picture in a Thunderbird Signature

Keep in mind that those images add a lot of bloat to your mail. If you just send a few sentences, then even a small image can easily make the mail hundreds or thousands of times bigger.


Targeted Spamming via Facebook

26. September, 2012

 

In the past few weeks, I started getting mails from friends which just contain a link:

hey, Aaron

Turns out that someone is analyzing my Facebook account and sends me mails using names from my friends list.

If you get such a mail, don’t click on the link. It probably points to a page which infects your computer with a virus.

Right now, these mails are pretty easy to identify as fake because the email address is wrong. But you should know that the sender address in emails is just a text; neither the sending nor the receiving computer will check what is in there. A spammer can write anything into that field. If the scheme starts to fail too often, I expect to see “better” email addresses.

This means as a receiver, you should never click on links in emails. As a sender, you should never share links by email.
