Re: exim4 for virtual domains
I am also interested in this thread, but I find some parts obscure. Would you please be more explicit in the following * put this into /etc/exim4/conf.d/router/160_local_virtual_users * add a domainlist virtual_domains = ... to conf.d/main/ that is, what is the syntax for '...' ? would that be 'domainlist virtual_domains = site1.net:site2.com' ? /etc/mail/aliases/$domain contains local_part - local_part and local_part - [EMAIL PROTECTED] mappings. and /etc/mail/aliases/$domain would be a directory with multiple files, symlinks, one file in tabular form?

Yes. This list holds all domains for which you want to do these aliases. /etc/mail/aliases/$domain contains local_part - local_part and local_part - [EMAIL PROTECTED] mappings. and /etc/mail/aliases/$domain would be a directory with multiple files, symlinks, one file in tabular form? for each domain in virtual_domains you need one aliases-style file to map localparts (string in front of the @) from this domain to real email adresses. for example, on my mail server: [EMAIL PROTECTED]:~$ cat /etc/mail/aliases/black.co.at postmaster: david abuse: david david: [EMAIL PROTECTED] [EMAIL PROTECTED]:~$ I also have my virtual_domain list in a file: [EMAIL PROTECTED]:~$ grep virtual_domains /etc/exim4/conf.d/main/01_exim4-config_listmacrosdefs domainlist virtual_domains = lsearch*;/etc/mail/virtual-domains You also want to go through the acl/ section and add the virtual_host list to all domain= tests which test for local_domains.

Would someone kindly post the relevant parts of an

appreciated.
thankyouall in advance
I tend to use arrangements like the following:
First, the filesystem:
/etc/exim4/virt_domains/domainA:
john: [EMAIL PROTECTED]
joe: [EMAIL PROTECTED]
abuse: [EMAIL PROTECTED]
*: [EMAIL PROTECTED]
domainB:
fred: [EMAIL PROTECTED]
abuse: joe
So, one alias file for each domain, stored somewhere. In the example
above, all addresses in domainA get forwarded to someone at aol.com, but
[EMAIL PROTECTED] gets delivered to the local user joe, while [EMAIL PROTECTED]
ultimately gets forwarded to [EMAIL PROTECTED]
Then, my domainlist is just:
domainlist virt_domains = dsearch;/etc/exim4/virt_domains
Router:
virtual_aliases:
debug_print = R: virtual_aliases for [EMAIL PROTECTED]
driver = redirect
domains = +virtual_domains
allow_fail
allow_defer
require_files = /etc/exim4/virt_domains/$domain
data = ${lookup{$local_part}lsearch*{/etc/lfrr/exim4/virt_domains/$domain}}
file_transport = address_file
no_more
This works best on systems where virtual domains are mostly forwarded,
rather than delivered locally, though. You can do the same tricks with
SQL, if you prefer faster access once things get too big for file
lookups.
If you want users delivered locally, Wouter's advice is probably very
good. But, this is the fun and difficult part about exim - the
configuration file is not just about setting config variables that have
a predefined meaning - you get to write your own logic for an
arrangement that works for you. It can make it more difficult (except
that there are usually snippets floating around for all the common uses),
but it is also way more flexible.

I agree, but the manual is so BIG! Thats the greatest

Browsing I found the following: http://www.marlow.dk/site.php/tech/ispworks Has anybody used this, how does it rate? It somewhat seems to fit. If my memory is good it uses postfix+mysql and courier. I didn't like it too much, personally. I've looked at what it does with the mysql bases and I found it to be a little of a mess. If you need something very simple, i'm sorry if i introduce yet another solution :) but there's qmail + vmailmgr. It uses no mysql base, which can be good if you've got a ton of accounts (think of the load on the mysql base if that's the case) and uses databases written on the disk (cdb format). There's a web interface for that, oMail, which is quite simple and is very convenient to use, well, personnally i prefer it to ispworks'. Try http://www.faqs.org/docs/Linux-HOWTO/Qmail-VMailMgr-Courier-imap-HOWTO.html It explains how to get a working qmail (the smtp program) + vmailmgr (to have virtual domains) and courier-imap (an imap delivery system, but you can have pop3 as well of course) It will have a link to oMail. it might sound a little complicated to install, but then the omail system is easy to use, if that's what you want. It supports email quotas too. I let people who're not techies at all manage their own domain, so it tells you how easy it is to use it :) -- Jean-Christophe Montigny Responsable serveurs assoces.com Etudiant à Grenoble Ecole de Management begin:vcard fn:Jean-Christophe Montigny n:Montigny;Jean-Christophe org;quoted-printable:Association [EMAIL PROTECTED] adr;quoted-printable:;;12, rue Pierre S=C3=A9mard;Grenoble;FR;38000;France email;internet:[EMAIL PROTECTED] title:Responsable Com Web x-mozilla-html:FALSE url:http://planetes.assoces.com/ version:2.1 end:vcard

What you really want to do is to get yourself acquainted with the most important concepts, and search the manual (hit '/' in info) when you need to know a specific detail; and if you can't find the detail, ask here or over on [EMAIL PROTECTED] In my view, those 'most important concepts' are routers, transports, ACLs, and (especially) string expansion.

Exim4 is way too flexible to provide a generic answer to this question.
What you should have is a router that looks up whether the local address
exists in some file or database, and a transport that writes out the
file to an mbox or maildir, possibly in a directory based on the domain.
Something like:
virthost_transport:
driver = appendfile
file = /mail/$domain/$local_part
will create an mbox '/mail/grep.be/wouter' for mail sent to
'[EMAIL PROTECTED]'.
Next up is the router. I'll give an example using an lsearch lookup,
because that is by far the easiest way to do this, but if you're
expecting more than a few tens of users and performance is an issue,
you'll want to replace that by another type of lookup (a cdb or ldbm
file, or perhaps something more sophisticated such as an SQL or LDAP
server). Run 'info exim4' and head for 'File and database lookups' for
more info on those.
virthost_router:
transport = virthost_transport
condition = ${if match\
{${lookup{$domain}lsearch{/etc/mail/users}}}\
{$local_part} \
{yes}{no}}
whereby /etc/mail/users is a file containing lines like:
grep.be: wouter roel leen
lists.debian.org: debian-user debian-isp
and so on.
