I have used real-time blacklisting in the past as well but I believe I turned it off for some reason. From what I read it sounds like a good thing to have greylisting - IIRC it did reduce my spam significantly, apparently because spammers don't retry bounced emails - so I will leave it on. > To answer your questions in order. > > 1. Your internet domain should be one of the domains that you receive mail > for such as : blahblah.com. I am sorry to be pedantic (because postfix is ;-) but do you really mean any domain? I receive mail for a handful of domains? How will it be used? E.g. I don't want email replying from one domain for another. As I mention, I current have this as "local" which has seemed to work fine, since I guess it is a (local) domain from which the server receives email for. Can I leave this as that? > 2.

By public host name I guess you mean FQDN? I have set this as the public host name of the server (which is the MX record) mail.mydomain.com but then I seem to remember emails replying with addresses like [email protected], which didn't look very good. I currently have this as "mydomain.com" and it seems to work ok (maybe). Can I leave this as that? Sorry, again just trying to be clear. > You should also set up a reverse DNS lookup for your mail server's public > name.

I have that thanks. Finally, if you don't mind me asking another question, in Mail Server > Advanced > Hosting, there are another two setting as well that are not very clear: 1. Include server's domain as local host alias Checked on. What does that actually mean? I can't parse that sentence (fragment)? I currently have all sorts of things in here, e.g. mail.mydomain1.com, mydomain1.com, <public host name>, mail.mydomain2.com, mydomain2.com ... 2. Enable virtual hosting Checked on. What does this actually do? Until today I think I had that on but with out any entries, and I thought I was hosting virtual domains just fine. It has all worked fine. Today I added mydomain1.com just to see if it would fix things. Do I need this? What does it do? Sorry for all the questions, and thanks again for your assistance.
