Hi. I have a domain hosted by a hosting service. They are running Postfix as the mail server there. I have started having a problem with delivery to local accounts, and they appear to be too stupid to figure out the problem, and additionally are not native English speakers, so I am having a lot of trouble trying to convince them that the problem is with their hosting. I was hoping if I describe the problem here, that someone would be able to give me some suggestions that I can put to them to check, as at the moment they keep telling me that they believe the problem to be a local PC email client configuration problem.
So my investigation so far, that I sent to them, is below. The problem is: 1. I compose an email from an email account that is hosted on my limedomains service to an email account that is also hosted on my limedomains service (it could be the same or a different account as the FROM account, it doesn't appear to matter). 2. I press send in my email client which sends to my local ISP smtp server 3. My local ISP smtp server tries to deliver the email to the limedomains server 4. The limedomains server rejects the email, and my local ISP smtp server sends me a bounce with the following message: -- Message -- This is the mail system at host mail.braintree.com.au. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.
