    Hello, how you add new e-mail adress ?Thank you

    • Matei Cezar says:

      You add user to AD server. The AD database will be queried by the mail server.

      • Iulian Murgulet says:

        … like postmaster user mention by you at point 16? OR without this user in AD we can finish the ssetup ?

        • Matei Cezar says:

          That user is just a local user used by iRedMail to manage the mail system. Once you’ll be integrated into AD you won’t need or ever use this local postmaster user to maintain accounts database. All your accounts will be managed from Samba Active Directory.

    It works with as many users your AD has defined, no limit so far. This design is destined for LANs access only. You can setup a domain such as domain.com to be accessed from LAN only, as long as the domain is not registered officially with a domain register. If you don’t want the mail system iredMail to read all mail users you can simply setup a OU or groups of users and query only those specific groups or OUs.

    • Iulian Murgulet says:

      Hello Matei, it would be nice to add this statement at the beginning of your tutorial – “This design is destined for LANs access only, and not to send/receive mails to/from Internet”, so anybody can understood this restriction from the beginning.

      Also if someone want to communicate with others Internet mail server. it is very possible to use a separate mail server (like a proxy), who can route mails to/from iredMail server to others Internet mail servers.

      This proxy mail server, will must know only the emails address used by iredMail, without any passwords. This kind of setup is very common for the guys who use Exchange (internal LAN mail server) and a postfix/what-ever as a proxy server.

    kindly clear me, how many users iRedmail 0.9.6 free version support, unlimited or limited users?

    one more thing, its working fine with windows 7 and via web access, but not working in windows xp with MS Outlook. any good suggestion for windows xp outlook client?

    • Iulian Murgulet says:

      If I remember (not so sure) you need some specific options in dovecot server. But if you can provide some logs from iredmail/dovecot/postfix, maybe I can help. What is not working (smtp and/or imap/pop), and how do you configure Faultlook (express or Mico?)

    Thx Matei/ Multumesc Matei

    You forget to say the most important thing, like the fact, that this setup will work only in Lan, not over Internet. Or maybe you do not say that from your point of view, it is a good idea to have a AD like tecmint.com so this dns domain could be resolved from lan but also from internet.

    From my point of view this is very bad. Any AD must be resolve only from lan. Any Internet host must be resolved by any dns server connected on Internet. It is not a good idea to put all your eggs in the same basket ;)

    Also if my memory is ok, in a previous tutorial wrote by you, you say you need to use some un-exising dns domain name for AD. Now you have another opinion. From another point of view is not ok that any very secure system(mail is not) to read your ALL your AD users. But I can say your tutorial is very useful.

    Let say iredmail is ok, if you do not need nothing special… but if you want some simple things like … lets say a new transport entry in postfix, you must dig … and maybe you will find this not so easy.

    What is your test case? For 20 users is ok? Any iredmail must be warned. .. this is an elephant. Apache, Mysql, postfix, and so on.

    Do you need an elephant? Can you ?
