Users getting bounced mails from recipients they never sent to

Hi guys,

having queer situation nowadays

my users are reporting receiving bounced mails from users they never send to.
Example, user@domain1.com sends a mail to someone, either internally or external domains say, user@domain2.com

user from domain1 will receive a bounced mail for failed recipient mail to user@domain3.com - for the same mail! even though the user didn't send to this person.

And it is happening across all my domains users, which are situated in different geological locations...

i did thought of a computer being spyware-d, but so many users at the same time....

anyone?
