Have an SBS machine setup as an SMTP server sending and receiving mail for the main domain OK.
For the second domain (remotely hosted) I have a POP connector for receive - not sure how to get send working properly.
For the remaining domains (again, remotely hosted) I can use any method SMTP, POP for send or receive.
Can modify domain A and MX records if necessary (as with the first domain). Would prefer simplest solution for send and receive through single SBS machine for multiple domains.
Which methods would you recommend and what is the quickest way to get set up.
Thanks for reading my post and considering your reply.
