Any one else had this:

From one of my domains I am getting a load of out of office or bounced mail messages from an email that I have not sent and an address that I do not use.

The Internet headers seem to be valid but I have run Norton and ZoneLabs to check with nothing found. I would rate myself as an IT/Internet pro given that I have been involved in PC/Macs for about 10 years.

My guess is harvesting to check an address? dunno but it is causing me some grief as I have avoided being infected or even just thinking that I might have been infected till now.

Any ideas?

spam?? i used to get a tons of them till i switched to gmail. it could always be something else. any other weird symptomother than the unknown mails bouncing back?

Ok - so two more scans overnight and still clean even with the Norton online scan.

Have changed the email domain password to see if that makes a difference
