Highly Recommended
by cronman - Oct 12th 2007 16:36:42
This is one of the best opensource packages I've had the pleasure of
working with, and working with it has been a pleasure.
Everything you need to run an email system is integrated into one project,
no need to mix and match, and the quality of the standard adhesion is
second to none as is the quality of the code.
Bugs, which are few and far between are patched within hours.
Take a look at the project homepage and look at the extensive
documentation and man pages. There is simply nothing about this project
that is not documented. There is a lot of reading to be done, but you will
find everything you need in the documentation.
The setup is flexible enough to accomodate any situation.
I've recently migrated from a cyrus setup, and am very very happy with
this new setup. My logs are a lot cleaner and its possible to trace things
on the system.
If you're running your own mailserver, take the time to get up to speed on
this one, it'll make life so much easier for you.

Courier Problems
by dmadance - Oct 24th 2004 10:15:15
I would not recommend this software for anyone. It does
have a steep learning curve and the support from the author
is not very good. Frequently updates to the software break
existing installations resulting in hours of work to fix the
problem, and the author typically can not help. This software
has some plusses, but the lack of good support and frequent
problems with upgrades more than cancel those positive
aspects.

Greetings from 2007. Things today appear to be very different from your

Migration
by JuanXarg - Jun 19th 2003 09:44:11
I had a server configured under Windows, running MDaemon. The thing is that
this email server has a feature called DomainPOP, that downloads email from
a POP account and then puts each email in the right mailbox.
I use this because I'm not 24/7 online, so I have this ISP that gets all
the mail for my domain and I download it later.
I don't know if I made myself clear, but the question is, as I'm migrating
the server to Linux, if Courier has a feature like the one I described, and
if it doesn't, is there anyway to do this?
Thanks

This can be done using fetchmail. There is no need to reinvent the wheel.

Courier-MTA
by Daniel Higgins - Jul 15th 2002 16:23:48
courier is an extremely well built mail server that follows the RFCs to the
letter (a bit too much to one's liking sometimes :)
save for it's (extremely) steep learning curve, it's an awesome package

Support for MacOS X
by Dan White - Apr 29th 2002 07:02:27
I am trying to set up a Mail Server for my Mac User
Group. I read many great comments about Postfix-
MySQL-Courier setups using the virtual features so that
e-mail users do not have a true account on the server.
This is the setup I want.
HOWEVER, I suppose the particulars of MacOS have not
yet been addressed.
I would be more than willing to help on the Mac side if I
can get an assist from the Folks Who Know What Is
Going On.
Please let me know.
Thanks.

Whats good about it.
by Ed - Jul 30th 2001 07:17:51
I've done a lot of work with qpopper, wu-imap, cyrus and
courier. Of all of them courier is by far the best as features go.
In the speed department Cyrus is faster but not by much.
I've yet to find another package with virtual mail support using
mysql buit in. The rest all need patches on the source.
The maildir format is awesome. Try deleting multiple virused
messages from multiple mailboxes without deleting other mail
using other mailstorage formats. (Okay it's also easy with cyrus,
but you have to rebuild each users database afterwards.)

Courier and users
by Talesin - May 10th 2001 06:27:54
I just installed Courier on my Digital Alpha, works quite fine and seams to
be reliable, but a sort question: Is it possible to create mailuseraccounts
that do not have any entry in the systemwide passwordfiles ?

You can use the userdb or mysql auth modules in order to facilitate
this... much like a virtual domain setup

Maildirs setup?
by Mike Carter - Mar 15th 2001 15:24:38
I have installed Courier and am looking forward to getting it to work. So
far everything looks correct, however I did not find any reference to how
to create/setup the maildirs structure for users! How do I set up my Unix
account to accept email via Courier? I saw in the "test" section
of the install directions a couple calls to "maildirmake",
however there was no explanation of those calls, hence I have no idea how
to create the proper directory structure for Courier to use. I'm pretty
sure this is tied to the errors I am seeing when I access Courier via IMAP
and try to create an IMAP folder. Also, when I log in via IMAP sometimes
there is a standard "inbox" folder and sometimes there isn't.
Once again, probably due to configuration of maildirs. Can someone give me
some direction? Thanks, and thanks to the author for what seems to be a
terrific app!

If using qmail as the MTA, do this as a user who will receive mail in
Maildir format:
echo ~/Maildir/ > ~/.qmail
maildirmake ~/Maildir/
This does two things:
* Tells qmail to deliver the mail to ~/Maildir/ in mail directory
format
* Makes a blank mail directory to deliver the mail in (otherwise, mail
delivery does not work)

Courier Rocks
by Steve McAllister - Dec 10th 2000 23:24:25
This is a very wonderful package. I am not an advanced user and I made it
work.
There probably are security issues as any imap server.
Just wanted to say that it beats all the others for features and quality.

I'd like to try Courier, but all I get from http://www.courier-mta.org/
is:
"Blacklisted You are seeing this message because you've been blocked from
viewing this site, by the webmaster. You are either on a uu.net
dialup, or receive connectivity via the uu.net network. Due to repeated
and persistent abuse from uu.net dialups, and uu.net's failure
to act on complaints of abuse, that network is blocked from accessing this
web site."
What gives?

uu.net is nortorious for not dealing very well with the "hit and
run" spammers who get a bunch of dialup accounts (usually using forged
credit card numbers), and spam like crazy. As uu.net slowly disables each
account, the spammer just moves on to one of the other accounts they
fraudulantly obtained.
The problem is that a lot of ISPs outsource form uu.net, but in the spam's
headers, the only information available is that the spam came from a uu.net
connection.
uu.net has not been very communicative with the anti-spam community about
their problems (of course, the anti-spam zealots are hard to work with),
causing there to be a lot of resentment against them in the
news.admin.net-abuse.email newsgroup.
I have not paid too much attention to the uu.net spam problems lately (I
finally solved the spam problem for myself by writing the open-source Kiwi
package, available at http://kiwispam.sourceforge.net)
I strongly suggest getting another ISP, explaining to your ISP that uu.net
needs to do something about their hit-and-run spammers.
In the meantime, I have mirrored some of courier's software at

I am unfortunate enough to have invested several class C's of my network
with UUNET (we pull IP space from them and route it with our AS). We are
lumped in with the spambag block. Until ARIN will release space to us
under our AS, I need a work-around to get to the courier-mta web site.
Your link is down so I wonder if anyone else could mirror the courier-mta
website/downloads for us poor unfortunate souls.

Re: Courier Rocks

I'll second that; the maradns site does not appear to have a /courier
directory.
Spam is a truly annoying problem, and its purveyors should be forced to
listen to an entire Slim Whitman album for each outgoing missive they send,
but I don't know that locking out legitimate users who happen to be using a
spammer-indifferent ISP is the answer. It can take an hour to get their
tech support on a phone call; why would they listen to our pleas to curb
spammers? Unfortunately, they are often the best in all other ways, or are
the only game in town (my case, at least for broadband).
It is of course the author's MTA and web site, and he can do what he likes
with it, but I think I speak for most folks when I say that I will try a
different MTA before I switch ISPs.

Possibility of security flaw.
by Koguma - Oct 4th 2000 09:27:43
I urge everyone to use caution. When sqwebmail is initially installed it is
setuser/group root. This is completely unecessary for virtual setups and
can pose a huge potential security hole. The workaround is to chown the
sqwebmail executable to the user and group that vpopmail runs under (or to
any other user/group that a compatible Maildir virtual email system runs
under), and chmod it g+s, u+s. This will only work for Virtual hosting
setup though. Email should be virtual regardless if the users are real or
not, but if you choose not to, you will be "stuck" with setuid
root.
