Couldn't understand it, Don,
This happened after I put the Delete to True as Erel told me.
1- I send an email
2- I received the well-known non-delivery message back in my PC., with the statement that the email doesn't exist
So far so good.. but
3- and this is the strange thing, the pop3 App in my phone received the same email non-exist message..
my question: If the email didn't exist then how did the pop3 server connect to it and sent it that error message:
