I have a bit of a convoluted question. I work from home and use Microsoft Outlook email. Over the years, I've had a problem with my outgoing emails being blocked by spam filters, and not reaching my customers. As far as I can tell, the problem might be because I use a three dongle, and there is a problem with the three SMTP being on Spam lists (I don't have a problem sending emails through my blackberry for example).
So, a) am I right about what's causing my problem? and b) if so, what is the best internet provider for me to choose if I wan't to continue to use Microsoft Outlook, but don't want the headache of this spam problem?
Incidentally why do you use a "3" dongle as opposed to a normal land line ISP.
I use a "3" dongle for 8 months of the year whilst I am at my holiday caravan where I spend most of the summer months and have never experienced the problem of "3" being on spam lists. Your individual email address may be on a list but I doubt if the whole domain is spammed.
