Received Email At Old Host

[DWD]

I switched hosts to TCH last week and started receiving email at TCH on or before the 9th. For two or three days, some email directed to me@domain.com went to the new TCH based webmail account, while some when to my old host's webmail account. After the 12th or so, everything went through TCH and my old account which I can only access now through its IP address has sat empty.

 

Until today the 15th. Today, for kicks, I checked my old account and it got a spam message received the 15th addressed to me@domain.com.

 

How could this happen? Isn't everything everywhere changed over after a week such that any email directed to me@domain.com would go my new TCH web mail account?

Broken DNS servers, broken proxies... there are reasons email could still go to an old location, but that usually means that the person sending the email has something that isn't configured correctly on their end (hence most often spammers).

 

When I moved my old domain, I had occasional spam coming to my old mailhost for over a month (in which I finally shut it down). Never had a legitimate mail come to the old host, though, so I wouldn't worry too much about it. The best thing is just to eventually get that old host shut off so that mail would bounce should it go there in the remote chance someone legitimate sends you something from a broken setup, so at least they know you didn't receive the message.
