I can send emails OK, but it seems for the past few weeks, some emails have been taking hours to arrive. Once I had about 30 emails arrive about a week late!!!
I had a friend email me some stuff about 3 hours ago - it hasn't arrived yet! I've had other emails through though, but I've emailed friends and would have expected to receive replies, and I haven't (same thing happened last week, then eventually they turned up...)
It just seems to be happening too regularly to be a coincidence...
