We are using three locations to send emails from this email address. One of the computers at one home, sometime in mid April, was put into a block of some kind for having a PUP (the best I can figure out, don't really understand this stuff.) We had the block removed and most emails are now going through from that one computer. The other computers never had a problem getting their emails to the recipients. The one computer that had trouble, now has Maleware Bytes and Adwcleaner installed, that's what we did to get out of email jail I guess. The problem is, any of the people that we attempted to email during the week or so that our email was in jail, even though it is fixed, our emails to those people are not getting to them still. We have to use another email address to get them to receive from thunderbird sent from our one computer. We are not super computer savvy as far as this behind the scenes computer technology goes and need help so that we can reach all our customers reliably. We did try to identify if we were still blacklisted and saw 1 hit but don't understand how to fix it now that we have the additional spyware type stuff added to our computer. Your assistance would be greatly appreciated. Thank you
