this long running operation.
Typically, these emails will appear to be "from" you as well as "to" you.. this is just a forgery and it doesn't mean that your mail is hacked.
Don't be tempted by the jobs on offer, typical positions are for money mules, reshipping scams or sometimes back-office functions such as translating emails or signing paperwork. Don't bother replying to the email as no good will come of it.
If you have an example of any emails using this address, please consider sharing it in the Comments. Thanks!
