Cogeco.ca

I've posted this previously and note others have had the same issue in the past.

Both my 'blueyonder.co.uk' and our 'virginmedia.com.' emails bounce back from 'Cogeco.ca'.

Yet, my 'gmail' goes though to its destination.

Anyone have any ideas why?

Sensible answers only please.

Re: Cogeco.ca

The bounce back message would normally show the reason that the email has been returned - is this not the case with these emails?

Re: Cogeco.ca

The bounce message usually gives more information as to why the mail was rejected, s well as the IP address of the mail server that was delivering the mail.

A good start would be to post it up (mask out any email addresses though).

Edit - oops Graham beat me to it.

Re: Cogeco.ca

I've just sent another 'test' email from my 'blueyonder' platform to see what comes back, (it takes a while for it to be processed) last time it was 'spamcop'. This was discussed in my earlier posts on the issue lat year.This time today it came back and was sent by my other half using her iphone on @icloud.com.  I'll have a look when she comes in.

Re: Cogeco.ca

That tells me that the Apple owned IP address 17.58.23.199 was rejected.

It answers one of the questions I was going to ask.  In that you would appear to be using the correct server settings.

Re: Cogeco.ca

And they have replied they 'see no reason to change their settings'. Also for virginmedia and blueyonder the same response. So be it. I'll use google to get across the pond then?

Re: Cogeco.ca

The problem with requesting a change of status for your email addresses, is that it's actually nothing to do with your addresses themselves..

Rather the blacklist providers look for malicious traffic and note down IP addresses sending the traffic.  NOTE: these IP addresses ae one's which are connecting DIRECTLY to honeypot servers.  So if the malicious traffic has come through an Apple server then that is IP address which will be recorded REGARDLESS of the email address that it comes from.

Blacklist providers simply act in an advisory role, they don't actually block traffic themselves.  Rather it is mail administrators that decide what to do if an IP address appears on a particular blacklist..  What Virgin Media (in the case of VM email addresses) or Apple (in the case of iCloud addresses) should be doing is monitoring their mail server IP's to see if they end up on a blacklist, and doing what they can to stop malicious traffic being sent via their mail networks.

In addition Cogeco.ca - should be looking at their antispam measures and consider whether they are being too strict, and perhaps rejecting traffic that would be better off filtered as potential spam.  It is they who've decided to block traffic that appears on these particular lists.

Re: Cogeco.ca

I agree, VM should be taking care of and responsibility for resolving this.

I remember some years ago we were in Florida on holiday and could not access our VM web mail, the site was being blocked by a Company called Brighthouse who are ISP there.  That had stopped though the next time we went after a couple of years or so.  I think it's still on here somewhere as I reported it when back home.
