Both sides need to check things... Titus needs to make sure the if mail is being sent from the web server local smtp, that the IP is not blacklisted... If sent from an actual mail server (different box) again, check the IP.

The same goes with the recipient, however that is most likely going to be worse than pulling teeth if you have to deal with a major ISP like Telus or Shaw.

I personally would recommend Canreef to check the IP's they are using, and if by chance they are being blacklisted, then you need to fix.

If Canreef email is being sent via a major ISP, then don't do it this way, as most major ISP's email servers are blacklisted at times.

Also if Canreef is hosting its own email/web services on a major ISP line, be careful, as the sending email port (SMTP) 25 is blocked by all major ISP's of the world now. What this means that even if you have your own mail server, IP, connection, but is provided by one of these such ISP's, most likely they are taking the email on port 25 and re-routing through their mail servers. And as stated above they have many servers, with some at times blacklisted, causing things like sparatic loss of email. You usually have to pay more to have an un-altered, un-filtered line with an open port 25. With some ISP's, they just won't offer an open port 25.

I just sold my hosting company, and I can testify, the one big issue I had was with the ISP's and how people had their systems, email, software, etc. setup... As this issue is known, but only if you know what to search for.

Hope this helps.
