Been having problems lately with mail delivery failed return to sender emails in my inbox for emails I know I haven't sent, the emails that are supposedly sent are always emails that I have just received (I hope that makes sense).
I've done all the usual stuff change password and security question scanned all my devices but to no avail. Any ideas anyone?
Tried sending myself from different emails but nothing happened. The only thing that's consistant is the emails that the problem occurs for example if I receive an email from Costco at the same time I'll get a mail delivery return at the same time,and it's the same for all Costco emails. I also had it on the emails to say I changed my password on virgin account as well
