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, [email protected] sends a mail to someone, either internally or external domains say, [email protected]

user from domain1 will receive a bounced mail for failed recipient mail to [email protected] - 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?
