Just an update as l'm finding it difficult to contact her at the moment.
She has however opened a hotmail account and got in touch. I posted her and she received this.
Sorry it's all so vague at the moment and l really appreciate any input.
To digress, i'm with Free.fr who are really just my ISP, are brilliant in the services they provide, but l can't stand their in-built email system. I switched to Thunderbird, using them as the supplier, and have had no problems since.
If she can't recieve hotmail emails through AOL's email system, but can through hotmail, then it is unlikely to be AVG causing the stoppages, it's got to be AOL themselves?
I think she's going to be happy with just the hotmail account, but l was just intrigued as to why AOL seems to be barring these and not others.
Anyway, will keep everyone posted.
Regards
