I have been sending emails to someone with an XTra email address for a few days, and it doesn't appear they have been getting any of these emails. It doesn't matter whether I use Xnets SMTP server or webmail via my domain but still connected via Xnet, these emails don't appear to be getting delivered. I have checked Xnets status page, and it does say that there is a problem with emails being delayed to Xtra and it has been going on for a number of days, and it appears that it has happened before. http://www.xnet.co.nz/cgi-bin/status.cgi?id=684 .

Delays in sending emails to yahoo/xtra

End:
No ETA

Body:

This issue has reoccurred, our Operations team are investigating and hope to resolve it shortly.

We apologise for the inconvenience.

The post refers to something that occurred previously, yet there are no historical status messages to the previous problem. Therefore anyone using Xnet should be aware that they may need to use another ISP if they are sending to Xtra email addresses, as they may not get the email.

Who hosts your domain's webmail? If mail from two different smtp servers (xnet's and your hosting providers) aren't getting through it really does point to Xtra/Yahoo's end, probably over aggressive spam filtering.

Tried a test sent from a gmail or hotmail/windows live mail?

Orcon are the webmail provider. The emails did eventually get through just 2 days too late. Perhaps yahoo are delaying email from an IP range. Even with webmail, isn't your ISPs IP address sent in the emails email header?

Yes, the IP address is sent in the e-mail. There is a lot of info in the header. I know of at least one ISP in the US that blocks e-mails from the XNet mail server's IP range and it takes a week before they send a reply saying it is blocked. The reply says it falls in a range of known Chinese spammers. When we joined XNet our work server blocked e-mails that I sent from home to work, but got that fixed very quickly.

Looks like they are on one blacklist atm (backscatter.org)
