Hi,
We use exim on our main mailserver and use an aliases file with
generated aliases and a login to email-address translation for outgoing
mail, in the config file:
(...)
# in the directors config
generated_aliases:
driver = aliasfile
file = /etc/nisaliases
search_type = lsearch
user = mail
group = mail
(...)
# and in the rewrite section
*@jvc.nl ${lookup{$1}lsearch{/etc/mail/longnames}\
{$value}fail}@??? Ffrs
We also use OpenLDAP. Now we wanted to generate the aliases and the LDAP
entries from our central NIS maps. There was nothing, so I wrote a
little program that can generate aliases from the GECOS field, put users
in one or multiple groups (also encoded in the GECOS field) and generate
the appropriate LDAP LDIF files.
It uses 2 fields from the password file to do this (in fact the source
need not be the password file...) and interprets them as follows:
<login-name> : <firstname> <middle-names> <lastname> , <mail-group> [
'/' <mail-group>], <phone>
For example:
loginname: first initials last, group1/ group2/group3, 345
jeanpaul: Jean Paul Something, marketing/ communications, 346
marie: Marie van der Burg, communications, 347
This results in the following aliases:
# generated aliaslist
last: loginname
filast: loginname
f.i.last: loginname
f-i-last: loginname
f_i_last: loginname
firstinitialslast: loginname

I was wondering if there is anyone who has interest in this program and
the companion script. If so, I will release them under GPL or just give
them to the exim developers group if they wish.
Kind regards,
