courier-imap why ?

[Varun]

Hello,

I trying to setup mailserver using :

Postfix-Procmail-Fetchmail-SpamAssassin-ClamAV-Courier IMAP

I have a little doubt about courier-imap function.

Procmail does the following :

" Procmail is a very flexible autonomous mail processor. It handles mail
that has been received by Postfix using .procmailrc 'recipes' that
determine what to do based on various aspects of the mail. You can
configure a unique .procmailrc for each user. My .procmailrc whitelists
some mailing lists and addresses, pipes everything else through
Spamassassin, and delivers the results to my maildir directory. "

Fetchmail the following:
" Fetchmail does just that - fetches mail from specified remote POP3
servers and delivers it to Postfix. "

If procmail delivers to maildir that should do. Maildir contains all mail

client folders.

What does then courier-imap do then ?

Thanks in advance

Courier-IMAP gives you the POP3/IMAP function.

Google's first hit for "Courier-IMAP" is: http://www.courier-mta.org/imap/

http://www.catb.org/~esr/faqs/smart-questions.html

You might want to give this a glance-over so that you can help yourself
answer your own questions. :)

Courier-imap allows you to read your mail (in your Maildir).

No offense but, if your are asking that question, you would probably be
better off with the infinitely simpler Dovecot at this point (or
whatever is standard in your distro).

If the role an IMAP server plays in a complete email system is
unclear for the OP, I doubt the choice of IMAP server software
makes any difference whatsoever.

Like many people before me, I must advise the OP to, quite frankly,
get a clue before continuing his/her mission. The questions asked
have been on a very very basic level and would be answered by reading
relevant documentation and/or a book that covers general questions
about email servers. One such book is _Linux Email: Set up and Run
a Small Office Email Server_:

http://linuxemailbook.packtpub.com/

I am one of the authors and I haven't read the finished book myself,
so I'm not in a position to either recommend it nor ask people to
refrain from buying it. However, it does cover most of the topics
that the OP wants to implement. A book that only covers Postfix
(such as Dent or Hildebrandt/Koetter) would be a good complement.

It was basically mail client that part that was
not perfectly clear.
I was thinking that delivery to mailbox was
enough.

So I am more at ease with Postfix. I still have lot

Your book comes from , ' Packt Pub. ' . I have to
find out my local book store can get a copy.

Don't worry after I am done I will write a nice tutorials.

So your patience with me will not go waste.

Thanks again

Is that OK ?

Thanks a lot

Courier IMAP is the piece of software that handles the requests from
the Email client, such as Eudora or Outlook, and tells them what is in
the Maildir, and delivers the messages up to them in a format they can
use so that they can display it nice and pretty to the user.

Otherwise, people would have to read their email by starting up an SSH
session and doing the following:

cd Maildir
cd new
ls -l
less ...

And most people are not interested in doing that.
Although, from time to time, I find it neat, myself....

That makes more sense than I did. Well put.

less(1) is for wimps! Real Men use "cat $MAIL", or if stuck on a wimpy
Maildir system, "cat ~/Maildir/new/*".

Oh, man, without specifying the '-vet' option,
you left yourself WIDE OPEN to all those ANSI-boy viruses 'n stuff.

This may seem like parody, until one does 'man cat'.
Still, I think our job on this thread is done, yes?

BTW, weren't you asking all these questions a few months ago on the
Bangalore LUG mailing list?

Yes devdas that is true.
And I know you are a Postfix and Postgre man.

Actually I had started Postfix then left it midway.
This time I will complete it.

So see you in Blug.
