I've just installed slackware 9.1, and did not include sendmail in the installation (because I heard you need to get rid of sendmail if you want to install postfix).

So I downloaded postfix-2.0.18.tar.gz (about 1.4 Mb), and as normal user I typed:

$ tar -xvzf postfix-2.0.18.tar.gz
$ cd postfix-2.0.18

Once I'm in the directory, I type:

$ make

and the output is

make -f Makefile.in MAKELEVEL= Makefiles
set -e; for i in src/util src/global src/dns src/master src/postfix src/smtpstone src/sendmail src/error src/pickup src/cleanup src/smtpd src/local src/lmtp src/trivial-rewrite src/qmgr src/smtp src/bounce src/pipe src/showq src/postalias src/postcat src/postconf src/postdrop src/postkick src/postlock src/postlog src/postmap src/postqueue src/postsuper src/nqmgr src/qmqpd src/spawn src/flush src/virtual src/proxymap; do \
(set -e; echo "[$i]"; cd $i; rm -f Makefile; \
make -f Makefile.in Makefile MAKELEVEL=) || exit 1; \
done;
[src/util]
(set -e; echo "# DO NOT EDIT"; /bin/sh ../../makedefs && cat Makefile.in) >Makefile

Anyone have any idea what went wrong? Do I need to include sendmail package when installing Slackware?

Thanks.

Usually you run ./configure before make.

Maybe that's not the problem here. Could be though.

Hello,

if you want things become a lot easier, you may take "postfix" for Slackware 9.1 from
http://www.linuxpackages.net!

Hi,

Thanks for the site url. Another question is about pop3/smtp.

So I've been browing the internet about postfix, and I found that there is the need of having external program for pop3, is this correct? So far I only have MySQL installed.

And is that also apply to smtp? that there is need for extra software? If that is the case? what does postfix covers then?

Postfix will accept mail to send via SMTP.

Just to clarify what a mail server is (Mail Transfer Agent, or MTA), it is a computer that sends and receives email over the Internet. You may be thinking, 'if it doesn't work with POP3 or IMAP or TLS, then how does it receive mail?' If you are at a Postfix server, you can read your email without any additional software. It was formerly commonplace for everyone with a mail account on a server to log directly into the server via telnet (or something else that gives you a remote session) and view their email that way, without using any of these protocols. These are client protocols for accessing mail remotely from a server.

It is also possible to run Postfix on each workstation as well as a central server and forward email from the server to the workstation. That way everyone could use email without ever using any of these protocols.

Thanks for the clarification on MTA and pop3/imap. I've been browsing at www.postfix.org , and found that postfix can be utilised with MySQL, instead of Berkeley DB (And I dont think I have Berkeley DB installed. MySQL is installed and running).

So I downloaded Postfix 2.0.18, then I typed:

$ tar -xvzf postfix-2.0.18.tar.gz

Then I go to the directory of where the postfix untarred to and typed:

$ make -f Makefile.init makefiles \
'CCARGS=-DHAS_MYSQL -I/usr/include/mysql' \
'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lz -lm'

And get the following error message:

make -f Makefile.in MAKELEVEL= Makefiles
set -e; for i in src/util src/global src/dns src/master src/postfix src/smtpstone src/sendmail src/error src/pickup src/cleanup src/smtpd src/local src/lmtp src/trivial-rewrite src/qmgr src/smtp src/bounce src/pipe src/showq src/postalias src/postcat src/postconf src/postdrop src/postkick src/postlock src/postlog src/postmap src/postqueue src/postsuper src/nqmgr src/qmqpd src/spawn src/flush src/virtual src/proxymap; do \
(set -e; echo "[$i]"; cd $i; rm -f Makefile; \
make -f Makefile.in Makefile MAKELEVEL=) || exit 1; \
done;

make: *** [Makefile] Error 1

Now, MySQL was installed out of the box (Together with Slackware 9.1 Installation). I believe the error is because of the lack of db.h file?

Is db.h related to Berkeley DB? Or if it's not, then do I need to do something when Installing MySQL? Or I misunderstood the error?

If it is related to Berkeley DB, does that mean I still need to install Berkeley DB, although I am going to use MySQL?

Thanks.

When compiling postfix on linux with berkeley-db and you get the: "No db.h found..." error, you can resolve it by:

Locating the "db.h" header file of berkeley-db (if you don't have it, then install berkeley-db development package containing header files, for your distro)
and then edit the "makedefs" file (located in the top-level dir where you untar'ed the postfix sourcecode):
Open "makedefs" in an editor and locate the "Linux.2*)" section of the file.
Fix all references to "db.h" so that they point to the correct location.

That should do it :-)
