This is a variation on an earlier thread where I had a problem sending emails to some @btinternet addresses. I have now discovered a variation on this non-arrival theme: a friend who has a Yahoo address can receive emails that I send from my tiscali webmail, but not from my normal Pipex address using Windows Mail(or webmail). And even the tiscali emails end up in his spam - but it turns out that he uses IE, not an email client, and therefore my instructions about where to check for blocked senders, etc. make no sense to him. Can someone please tell me (so that I can tell him)where to look in Yahoo webmail for the settings that are sending my mail into his spam folder. And finally, he believes that because my address is in his address book I cannot be in his blocked senders - is that the case? Don't know his OS, mine is Vista.
