I don't think I'm mixing them up: one of them is a directory, so hardly
can contain any code at all ;-)

(Well, the other _can_ also be a directory, but YSWIM).

Funnily enough, I switched to Claws because I found KMail horrible...

Are you mixing portage/env up with portage/package.env? The latter loads
conf files from env that contain variable assignments.

A simple example line from my /etc/fetchmailrc is:

poll pop.mail.server.example.com proto pop3
user "your.username@there", with password "secret", is 
"your.username@here" here, ssl;

That's all...

As an MTA should, Postfix transports email. It can also handle local
mail transport (say, in maildirs) and I guess one could call that
"storing" mail, but to me that's stretching the term too far.

As the OP is using Postfix to feed data to Dovecot, I strongly suggest
configuring Dovecot's LMTP as a mailbox transport instead of having
Postfix write directly to the file system.

While Postfix certainly won't serve up email via IMAP it definitely
does store email.  You are correct that you'd run a separate IMAP
server.  They need not be on the same host assuming they can both get
at the maildirs.

http://www.fetchmail.info/ is the most obvious starting point, and I
assume you have found that one. Fetchmail per se is not Gentoo-specific,
so you're better off asking questions on the FM mailing lists should you
find the manual and FAQ insufficient.

You can run fetchmail as the user you are logging in with or as a
separate user. I suggest the latter if you want to run fetchmail in
daemon mode, for standard privilege separation reasons. I used "foo" as
an example. If you want to run fetchmail on demand only, a dedicated
user account may be inconvenient, and you did not say which method you
are aiming for in your OP.

Sounds about right... from `man portage`...

  package.env
  Per-package environment variable settings.


(moreover, we're using a custom parser IIRC and not all bash syntax will
work)

Again IIRC, when I tried using env for a similar purpose, it didn't work
at all, it seemed the only things valid in those files were variable
assignments.  If possible, I would of course much prefer this way, as is
avoids an ugly switch on the package name.

Do you know what I could've been doing wrong?  I think I brought it up
on the list, I'll try to dig up the thread.

Yes, of course. Postfix feeds Dovecot here.

That's because I don't yet know enough to know what questions to ask; that's 
why I hoped I'd be pointed to a general guide or explanation.

I thought I was clear enough: I want fetchmail to fetch POP mail and feed it 
into the local postfix (and of course dovecot) mail system. What else do you 
need?

I assume you mean ~/.fetchmailrc, a file in my home directory, no?

The ebuild installs /etc/init.d/fetchmail and /etc/conf.d/fetchmail, so it 
seems to expect me to run as a daemon. But then there's no sample 
fetchmailrc, which surprises me.

Postfix is an MTA and does neither store email nor lets you access email
via IMAP. There must be an IMAP server in your mix somewhere (e.g.
Dovecot or Courier).

Your needs depend on what you are trying to achieve, and you have been a
bit vague on the details. If you plan to use a single fetchmail process,
~foo/.fetchmailrc (with foo being the user you want to run fetchmail as)
usually suffices.

If you run fetchmail as a daemon, then you need /etc/fetchmailrc. If you
run it manually yourself, then you need ~/.fetchmailrc

Read the docu, in particular the bit about whether or not to delete
mails from the server. Set it to NOT delete mails, then you can test it
knowing that you won't lose anything.

I believe it keeps a log file of what it's downloaded, so for testing
purposes you may want to find and delete that.

And if you run it with the --verbose option, it'll tell you what it's
doing. I generally pipe that through the "tee" command, so I can see
whether it's doing what I expect, then I can examine the output in more
detail to check.

Beyond that, I would say you're doing a right thing. fetchmail is good
software. The only reason I'm not using it is MySQL broke, which took
out my virtual usernames, which broke postfix and fetchmail delivery :-(
And I've never got round to fixing MySQL.

Wol

[gentoo-user] Setting up fetchmail to feed postfix

[Peter Humphrey]

Hello list,

My MUA is KMail-2, which seems to be all right for others using IMAP but is 
very far from robust when fetching POP3 mails. I've tried alternatives to 
it, but none of them suit me - in particular, claws-mail is horrible, 
requiring a very different mental model just to operate it. Therefore I'm 
trying an evasion, which is to use fetchmail to retrieve emails from my ISP 
and deliver them to postfix, which can then serve them via IMAP.

I already have postfix working, I think, collecting emails from the LAN, but 
the fetchmail documentation is confusing and I hesitate to jump straight in 
for fear of losing emails.

Is there any guidance on setting up fetchmail on Gentoo to operate in this 
way? I've searched in likely places but the Gentoo docs are long out of date 
and others don't help much, so I still don't know what to add to /etc/
conf.d/fetchmail, nor whether I need a ~/.fetchmailrc or an /etc/fetchmailrc 
file (no sample comes with the ebuild).

What does the panel think?

You do have a choice, use /etc/portage/env. here's one I have to patch a
specific version of a package

% cat env/app-cdr/cdrdao-1.2.3
post_src_unpack() {
cd "${S}"
epatch_user
}

You could also use post_src_prepare to apply the patch after any the
ebuild effects.
