I only have further questions

It has been 10 years now since my e-mails would show up days after being sent and spoke to my sister a few states away and she was having the same issue; we were using G-Mail; we switched to Yahoo and have never had a problem since.

It is very disturbing to receive an e-mail days after being sent but have no reason why.

Off topic but have always wondered why I could send an e-mail to a girlfriend in Pa and she would be really upset as there was perhaps 12 strange characters that looked like Chinese; my GF thought I was playing games and when I asked her to return the e-mail she received it was just as I typed them until months later I received one of the strange looking e-mail messages myself ... I am still baffled but I know little about tech.

I have had no issues for years now but am curious about this problem.
