losing emails - Help

[bobt]

I probably send just three or four emails a day on average. Most of these are replies, so using the reply button, so I know it's not me with clumsy typing fingers getting the address wrong.

Porbably one in three emails seems to get lost in the ether. They are not recevied, and are not being diverted into peoples spam folders aor auto delete folders.

Is this a common problem, or possibly something to do with the email provider that I use. I have stuck with the same provider from the dial up days, as I would prefer not to change my email address, and access my emails via their webmail service.
