Postfix Mail Server

I am now studying postfix mail server. Already setup postfix on server22.hosthat.com and is working great with basic configuration. Now it only handle one domain name, that is real user (system accounts).

 

I have brought The Book of Postfix

 

http://www.postfix-book.com

 

I have read first few chapters. My plan is to make a mail server with postfix + LDAP.

 

Postfix seems easy to setup compared to Qmail. I have installed Postfix with out much reading. Qmail, i have to spend lot of time to get it working, mainly because it need several small scripts and two other supporting programs to get it working.

 

Another advantage i see over qmail is postfix is still actively developed. Qmail, you need to patch to get it working. So descided to go with postfix for my new mails server project.

 

I have added new forum for postfix on my qmail forum at

 

http://qmail.netfreehost.com

 

BizHat.com Home Page redesigned

New Free Hosted phpBB forum site

I have created a new site for free hosted phpBB forums at

 

http://phpbb.bizhat.com

 

Just added one FQA entry, need to create some more FAQ's.

Mail Server Setup with LDAP

Last two days i was working on new email server setup with LDAP.

 

Installed OpenLDAP on local FreeBSD server, still can't get it working with qmail or postfix.

 

I have to read a lot of documents qmail and postfix as i may switch to postfix.

 

I have some experiance with running qmail mail servers. For new email server, qmail was the inital choice, but postfix seems better option, so have downloaded and installed it few times yesterday. It works well, no path is needed like qmail. qmail need patches to work, postfix is still active developement and work with out any patch.

 

Now need to get any of these work with LDAP. With qmail-ldap, if user is added to LDAP, first email will create required folders. Postfix, not sure it will do this or manual creation is needed. If postfix also auto create user folder, then i will go with postfix.

 

Today agnel moved his web site to BizHat CMS

Builing MySQL RPM from source RPM

On my Fedora Core 3 local test Linux server, MySQL version was 3.x

 

I upgraded MySQL with bindary download from MySQL.com

 

Few days back i tried to compile a program with mysql library and got error, it seems mysql-devel package is missing, so compiled RPM for MySQl 4.1 as per

 

http://fedoranews.org/contributors/tony_smith/mysql/

 

It take about 4 Hours to compile. On my FreeBSD server, it always compile from source when installing from ports, it seems FreeBSD compile is faster than rpmbuild, may be it have to do more work.

Portupgrade pkgdb.db: unexpected file type or format

After upgrading FreeBSD from v6 to 6.1, i tried to upgrade all software installed on the server with portupgrade.

 

I start getting the error

 

[Updating the pkgdb <format:bdb_btree> in /var/db/pkg ... /var/db/pkg/pkgdb.db: unexpected file type or format -- Invalid argument; rebuild needed] [Rebuilding the pkgdb <format:bdb_btree> in /var/db/pkg ...

Command failed [exit code 1]: /usr/local/sbin/pkgdb -aFQ

 

The problem is fixed by deleting the pkgdb.db file

 

 

server26# rm /var/db/pkg/pkgdb.db
