First let me say that I am very new to FreeBSD. However... new enough to be dangerous. I have been searching around for server software to replace my Windows servers and seem to have found that FreeBSD will more than suit my needs for what I am trying to accomplish and with that my interest was peeked. So as anyone with a new powerful toy, we play around with it until we make it work.
I have recently set up a mail server for our company using the tutorial at http://www.purplehat.org/ using FreeBSD 9.1, Maia-Mailguard, MySQL, Dovecot, Postfix, Apache, PHP, PostfixAdmin, SpamAssassin, FuzzyOCR, Clam AV, Pear, Maia-Mailguard, Mailgraph, and Roundcube. Would have liked to use Squirrel Mail, however it kept running into an error on install. Something about it would not run on PHP 5.
I started with this as a full solution as it seems to be a step by step solution, therefore allowing me to educate myself instead of bothering others. Through the process I encountered a few issues and was impressed that through help files I was able to solve them myself.
Anyways, in being new to FreeBSD, I had a couple of questions that I have run into. I was able to get the server up and running flawlessly. Everything works very well. It provided a complete solution as to what I was looking for.
I have noticed in my maillog file that we are experiencing a lot of brute force attacks. I am to understand that this can be eliminated or slowed down by Fail2ban. I was unable to find a dummies install tutorial on this. I tried the tutorial "Secure a FreeBSD mail server running Dovecot with Fail2ban" (https://sites.google.com/site/ghidit/how-to-2/secure-a-mail-server-running-dovecot-with-fail2ban) and it appeared to fail miserably. I'm assuming my lack of FreeBSD configuration knowledge has confused me. Can someone point me in the right direction please?
My second question is that I would like to have the SMTP server listen on another port other than 25 (maybe 587 or 465) and also to use SSL in it's incoming and outgoing connection. Could someone steer me in the right direction for that as well?
Thanks in advance for any help you might can give to me.
