I am new here and not an expert on email servers or computers. Since yesterday, at work, I was not able to send emails using our work mail accounts to a few ISPs, such as look.ca, and 2 other independent companies.
My computer does not have any viruses or spyware, and I do not send spam.
I can not contact our mail host because we don't know who they are. Long story short, our IT guy quit suddenly about half a year ago and left us with no info/password/whatsoever. I called up the company that should be hosting our mail server but they said they can't pull up our accounts. So, long story short, I am unable to contact our ISP/mail host for help.
Below is one of the three "Mail delivery failed: returning message to sender" that I received. How can I get my email working properly again??? (I've "xxxxx" the names of the people"
By the way, all those emails have different .jpg and .wmv attachments. (I was able to send those email to my personal account, Rogers.com accounts)
Thanks in advance.
