For the past few days I've been trying to email a friend who works for Hammersmith Town hall and I've had her address in my contacts for years only now is there a problem. She can email me those are fine but when I email her, regardless of whether I reply directly to one of her emails or whether I start a totally new topic: my e-mails are returned to her. This also happened to someone else I know who e-mails her regularly yet she says she's receiving email both privately and work variety. I never understand the jargon of these messages but it says something about my email not getting through because my server is in RBL any idea what this means? I wondered whether she may have added me to a bloc senders list or whatever the Outlook equivalent is as she said one of my emails was in her deleted items the other day and she'd not even seen it. Whilst on subject of emails: I sometimes receive every e-mail twice why might this be? Mandy.
