Well, I'm not entirely sure I agree, mandrillapp is used by a large number of forums and other sites sending out newsletters, they sure will miss out on a lot! Security conscious people will hopefully do a little research or ask the administrators - and believe them.
Mandrilapp might be used by *a large number* of forums (although after decades of working in various areas of IT this is the first time I hear of it), but relying on it for sending mail isn't what will set the security conscious on "alert mode".
What is truly troubling is that the
links included in the emails point to the Mandrilapp servers, instead of pointing to the forums directly. It is completely unnecessary and the only purpose for doing such a thing is for the Mandrilapp people to do some kind of tracking of who responds to their emails.
It is a
standard security practice to never click on a link that is not from someone you know and trust, and absolutely never when the link is different from the location that you are going to.
In the case of Android Forum's emails, instead of going directly to the threat at androidforums.com/threads/... the "View this Thread" link points to mandrilapp.com/track/.../androidforums.com/... which is exactly the kind of link that the best security practices say "never click!!!"
After researching, it is not a problem for me. I just hit delete on the email client, fire up my browser manually and go to androidforums.com where the alerts send me straight to the thread. Clunky, but secure, and does not require the risk of exposing myself to a 3rd parties or believing the "trust me it's safe" words, the same words used by every scammer in the world.
Most people nowadays (technically savvy or not) follow the standard practices, but many of them won't bother looking for alternative ways of making good use of those emails. My suggestion to change the links you include in emails is simply to help you avoid negative perceptions.
