[BNM] Email hijacking

[Jeff Horne]

Hi all,

I need a bit of email techie help if you're willing.  Over the last week the
amount of emails in my inbox has increased about 10 fold and most of them
are saying "undeliverable" or things like that.  I'm not clever enough to
figure out whether my email has been hijacked and is being used for spam or
if it's just a new method of getting me to read spam email that gets sent to
me.

Anyone know any way i can check.
For the last 2 months i've only been sending and receiving mail via an web
browser panel if that makes a difference.

Ta,
Jeff
