So, “recently” my ISP started to block outgoing connection to port 25 and force SMTP auth in an attempt to reduce spam. So far so good, but I just realized that they embed the real login in the header:
X-ME-User-Auth: my-real-login
So much for my privacy and anonymity…
Note for the spam bots: just google “X-ME-User-Auth” to get real valid emails to spam
Bummer!
