I have a single case problem, it relates to selecting the correct mail server. A group wants to create their own business PHP website, where the public can read articles, news etc. and the staff can login and check his mail, update articles, wherever he is, on the same site.
I am tasked to search around for finding/selecting a good mail server (and there are many...) that PHP can connect to, to view received mail, send mail, manage user address books, easy spam/junk control, but also manage mail groups (such as mail sent to firstname.lastname@example.org will be forwarded to members email addresses that are registered to groups projectx-devel), etc...!
The PHP side is not my problem, but my problem is to find and recommend a mail server with not too many protocols for easy PHP development (I cant imagine managing IMAP/POP/LDAP/SQL/FILES/ etc in one site..!). Eg. Is there a mail server that stores/sends/verifies mail from a mysql database? This would reduce the protocol to standard SQL, and (arguably!) faster and easier development for the dev group.
The dev server has per default CentOS 6.4 with Mailman installed, which is a world standard, I believe. I have been told that it is complicated to manage, and in this case, maybe not the easiest (I don't know)? I have also been told about the iredmail mail server, which seems pretty close to what I am looking for!
Has anyone else had a similar research task? What are any suggestions, recommendations, for mailservers in this case?
