What should I do if emails stop coming?

 
Just wait! The loss of emails before you receive them seems to be fairly rare and they usually turn up with patience. There is no real need to put out a general message of concern - it only panics Forum members and results in a run of inconclusive emails.

But do check if your emails have been misdirected into a Spam folder either in your own local email program or in the spam folder of your email service provider. If this seems a common occurrence with your anti-virus program or your email service provider then they will offer a mechanism whereby selected email addresses can be included in a 'white list' - a list of acceptable email addresses. This is sometimes called  Mark as Not Junk, Add to Contacts list, or Address Book - depending on your email provider's terminology.
