BT emails non-delivery

  cleddau77 20:27 25 Sep 2003

I've used BT Internet without email problems (apart from their insistence on CLI and their blocking if not BT line) for 7 years.
I recall earlier this year something in computer press that some ISPs were blocking emails because of a security non-compliance at BT.

The vast majority of emails still get through. The problem is with the ISPs that do not receive my emails there is no mail rejected msg so I am unaware that msgs have not got through. I have been able to receive incoming msgs from these ISPs even though they don't receive mine.

I send & receive using my own domain name with Outlook 2000 SP3. Today I set Outgoing server requires authentication and I can now send to ISPs that previously could not receive but now they cannot send to me. i.e. problem reversed.

As there was no problem until earlier this year, is there anyone who can
1) Explain what is happening &
2) Come up with a fix other than changing from BT.

I'm sorry to say that it's not just BT. AOL are also doing this and I believe Freeserve, and maybe others as well. I don't know why they are doing this, except for the reasons I have read about so far.

It is alleged that the major ISP's are at times blocking large amounts of incoming mail in an attempt to deal with "Spam". Just how they come to use this method of dealing with it, is beyond me. Regards. j.

Found the following reason why the incoming email was blocked.
Query - is
i.e Spamcop has blocked every user on that CalifornianISP.

I then tried to raise a query with my Domaain name host from my ISP BT and lo and behold it got blocked by another Spam blocker because the dynamicall allocated IP adress had been used by a spammer in the past.

At this rate, not knowing whether email has been received or not, email is going to be unuseable. As a business, I prefer receiving spam I can delete and know that emails are being delivered!

This is not progress!

I agree and hope the ISP's have it sorted soon It's frustrating enough waiting for a reply to e-mail, but not knowing if it's been allowed through is even worse. j.
