Over the past few days my e-mail when trying to send a message with an
attachment stays in the outbox but the people I am sending it to
receive it every minute until I delete the message manually. I had sent
a message Sunday and was away for a few days and my friend received the
same e-mail over a 1000 times until I came home a few days later!

Not sure if this is related but this has only started happening since I
installed Spam fighter software.

Please can someone help me?
