Several people are concerned about the hit and miss email issues. This is related to the virus which came out early this week as ISPs are having issues with the volume of email generated by it. Read report today which said 3 in 4 messages are now related to this virus and ISPs services can not handle the volume. This results in dropped services and lost messages for both incoming and outgoing messages.
I have seen the degeneration of reliability of email services with the emails I send between my home account and work accounts along with email to friends.
Luckily (knock, knock) our server and service provider has not been affected by this issue. I may have spoken too soon as this virus is a ticking epidemic ready to release a flood of virus email messages.
