I have a small hosting plan that I've had for awhile and have a few email addresses that are associated with it that I use. When checking my mail this morning I seen that 2,500+ were waiting to download when checking my mail with Outlook. I may get 80-100 emails at one time but never in the thousands. Then when they started coming in it was alot of spam returned and mailer-daemon failure notices.
It looks as if someone has got access to my email accounts and is using them to send spam. I at most send 5-6 emails per month. The question is what do I do about it, just change my password? Any help would be appreciated. Thank you.
