A friend of mine, who regularly sends emails on a daily basis, is complaining that emails are not reaching me. This happened on one occasion last week and this morning. As of yet, some hours after having had the message sent to me, I have yet to receive it. He has tried a couple of times since and still no email. Eventually last week, I did get the multiple messages that were sent during the day in one go in the early evening. I have checked the webmail and nothing shows as having been received yet so of course that means that it has not arrived at my desktop either. No doubt the emails will eventually reach me, but is there an explanation for this? I am receiving emails from all other sources except this one. I can send to him and he received it just fine.
