I was talking with one of my co-workers the other day, swapping tales of strange issues we have had to deal with. We got onto the subject of email and how people never read the error to find out that they spelled the email address wrong, but instead need an IT tech to come point it out. And then he admitted that he had something similar when he was first introduced to computers.
It seems that when he was new to email he had sent a message to a misspelled email address. The message of course bounced back with the error that the user did not exist. After trading messages back and forth with who he thought was an actual person, he finally asked the local IT guy, "Who is this postmaster guy?"
It just goes to show, we were all once newbies making simple mistakes and assumptions.
