My apologies if this is not the correct forum for this query, but I'm new to this.
Ever since I subscribed to Telewest blueyonder / Virgin Media broadband some years ago I've used my existing e-mail address to send and receive e-mails. I use Netscape, and had the outgoing server set as smtp.blueyonder.co.uk, and the incoming POP mail server set as mail.which.net for my e-mail address which is in the format surname.which.net. I've had no problems with this for many years, until a few days ago.
Last week I discovered that some e-mails that I had sent to people hadn't arrived. It wasn't every e-mail, and it was hard to keep a check on because it was intermittent. So I decided to bcc every e-mail to myself, just to check that they were going through OK. I started this on 1 April, and then on 2 April our Virgin Media broadband and TV went down as part of a general outage across North London. On the morning of 3 April I wasn't able to send e-mails at all, ie they wouldn't leave my computer, so I contacted VM using the contact form on the website. Their response was that they didn't support third party e-mail clients.
When I next tried to use my e-mail the system asked me for my blueyonder password which I provided. Since then the e-mails have been leaving my computer, but they haven't been received by anyone to whom I've sent them! So I haven't been able to send any e-mails using POP3 via my computer since yesterday morning - 4 April. I can receive them via POP3, and I can both send and receive using webmail.
My partner, who has a secondary e-mail address on my which.net account in the format
firstname.surname@which.net (the same surname), has been able to send and receive e-mails using this secondary account without any problems.
I contacted VM again last night via the website contact form to point out that the problem isn't with a third party e-mail client, but so far I've not even had an acknowledgement.
Can anyone suggest to me what the problem is likely to be and what I can do about it? Thank you.
