I have a dedicated server that runs on Debian 7 (Wheezy) 64-bit with ISPConfig 3.
I have two domains, they are both pointing to the server correctly, FTP works fine, website works fine.
I need a mail server/software to be installed (SMTP, POP3, IMAP) on the server, and it should work with potentially any other domain that I would like to run on the server. You should instruct me how to add new domains/create new mailboxes in the future.
You have to also ensure that e-mails sent out are received and will not go into spam (dkim/reverse etc.) and that we will not receive spam (SpamAssassin etc.). You can also look into [url removed, login to view] - not sure if able to run alongside ISPConfig though.
The domains are configured at the registrar with the records as following:
Host - Type - Content
@ - MX - [url removed, login to view]
@ - A - (IP of server)
mail - A - (IP of server)
www - A - (IP of server)
You will be provided the access you need to the server. You should complete this while on Skype with me (at least partially) and also explain what and how you are doing it.
