You don't need to find out unless you are a system administrator where you can read log files (/var/log/mail.log) if you are a user on any mails you have to protect only your self. And here some simple tips;

 

1. Create an e-mail to a reliable domains or if you own one that's better. Try creating from gmail.com that is one of the best these days. I really don't recommend Yahoo or especially Hotmail, don't ask why.

 

2. Make your password bit longer at least 6 alpha-numeric, alph-numeric means mix A to Z and 1 to 9 including special characters like !@#$%^&*

ie: myp@22w0rd (ok that is 10 but that is safe enough)

 

3. You must use GPG

More about GPG:

http://en.wikipedia.org/wiki/GNU_Privacy_Guard

http://gnupg.org/

 

GPG will help you to secure you, your self and your opponent you want to send your mails, GPG is a tool to create encrypted e-mails and other documents.

 

Good practice will start from you then to your family circle and later to your circle of friends.

 

These days bad guys (so called hackers but hackers is not a right definition, they are called black-hats) go directly to your mailbox and view your mail but if you have GPG they cannot view it if the mails are encrypted, they really don't care about your password anymore they can infiltrate directly. Doing a password cracking or guessing is a typical script-kiddies group of hackers, script kiddies are people who pretend they are good but they are not!

 

Ok if you ask my own opinion now I do use the following;

1. My Own hosting km33.com and as well gmail.com

2. I use longer alpha-numeric passwords

3. I do use GPG and especially encrypt sensitive mails around me.

-- Application I use (Note: I don't use windows, so sorry for windows user, but there are a lot of windows crack version software around hehehe)

- I use Linux Ubuntu 'Gutys Gibbon'

- Seahorse 'encryption key manager' for keeping GPG keys and keyrings

- Evolution for my mail client and I fetch gmail.com and km33.com over that application in TLS Encryption mode for receiving and sending message

 

Hope this will help you.
