If an email is not received what happens at the senders end?
If an email is sent everyday from 5 June until 22 june and they are not received what would the sender receive in notifications/error messages? Is it possible that no error messages are created and the email is not to be seen anywhere in the senders program? attached screen shot from receivers program indicating nothing received. Thanks

A sender usually would be notified if the destination mail server expressly rejected the message before the connection was closed. Common reasons for this include a mistaken email address or a policy violation (e.g., spammy message). A sender also is usually notified if the destination mail server does not accept the message within a reasonable period of time for non-permanent reasons (e.g., the server is down).
After the destination mail server (or front-end filter) accepts a message, it could be delivered to the intended mailbox, or it could be filtered as viral or spammy, all without any further indication to the sender as to what happened.
