Hi, I currently have postfix and dovecot and courier all installed and config. Now the problem is that I get errors saying
Code:
Recipient address rejected: User
unknown in virtual alias table/code]
I have it set up with mysql but I have no clue why I am getting these errors. Also I can use thunderbird app to login to my e-mail account on my server. Any idea why I get the errors and what I should look at or try? Is there any good material that will educated me as how e-mails travels from and to my server? I can login to my mail account using the mozilla thunderbird and I can send e-mails with no problems. I just can't receive them for one account.
I need to fully understand how e-mails get delivered. Because I plan to allow customers to make their own e-mail account for their own domain name. I be starting a hosting company. So, I need to know what is needed so I can automate the process, where people that have their website hosted on my servers that they can create their own e-mail accounts.
