Sniffer showing username and password

I was using smartsnif on my pc. whenever i recive and email i could see the username and password for all my email account setup in outlook. is that normal or theres some security issues somewhere

If your using POP or SMTP in outlook, both protocols send plain text usernames/passwords by default. Surely there is some security issue with this, sniffers can definitely see the passwords. However, you can configure outlook to use SMTP authentication and SSL encryption if the POP/SMTP servers supports it.

If your using IMAP in outlook, I think you can configure authentication and SSL the same way too.

Tell us if you need more help on the configuration.
