Today I found out someone can’t send me any emails. When they try, it comes back to them as “undeliverable.”
In fact, I am afraid it is possible that no one from that person’s domain is able to send me emails. I have been getting emails from that domain at the rate of five or six a day, until about four days ago–exactly when this person started having the problem–and during that time, I’ve received no other emails from that domain either.
I’m working on confirming whether this is in fact the case or not.
But in anticipation of the possibility that it is so, I am wondering, what could be causing this, and what could be a solution?
My own email address is through outlook.com.
The other domain in question is a university’s ***.edu domain. I’m fairly certain probably all these guys are using the Outlook program for their email, just in case that might be relevant.
ETA: Confirmed: Emails from the ***.edu are not reaching me.
