I have recently found that my emails are not being received by my Mac Mail from my account with the ISP Virgin Media, although I was able to send emails. At first I blamed Virgin but, after much investigation, I tried turning off the Mail Shield and, lo and behold, all my emails appeared on my Mac. Is this a SSL related issue? There were problems in this area with an earlier version of Avast but then it issued error messages so you knew where the problem was. With my current problem I get no indication that anything is wrong, I just do not get my emails. I am now having to operate without the Mail Shield unless anybody can advise a suitable course of action or until Avast is fixed.
