Mailing List Archive: How to avoid 1000's of files in ~alias/

Hi

I'm about to setup a forwarding host for ~300 domains, what I want to
achieve is users having mail adresses xxx@yyy-domain.dk, to have
mail-aliases zzz@city-name.dk

My plan is to have, the following in /var/qmail/controls/virtualdomains

city1.dk:city1
city2.dk:city2
...

This is to avoid too many .qmail files in ~alias/, but each of these
virtual domain can potential contain 1000's of mailadresses, meaning
1000's of files in eg. ~city1/

Does anybody have any suggestions for solving this problem? Or does it
matter at all, if you have eg. 20000 .qmail files in one directory?

One Unix to rule them all, One Resolver to find them,
One IP to bring them all and in the zone bind them.

Don't use lots of .qmail files, use users/assign instead. Here is how:

* Set up controls/virtualdomains just like you planned.

* For each address zzz@city-name.dk that you want forwarded to
xxx@yyy-domain.dk, cause the following line to be in users/assign:

=city-name-zzz:alias:111:222:/var/qmail/alias:+:fwd-xxx@yyy-domain.dk:

and remember to run /var/qmail/bin/qmail-newu whenever users/assign
is updated. Here 111 and 222 are the uid and gid of the alias user.

* Finally, do

echo '|forward "$EXT2"' > /var/qmail/alias/.qmail+fwd-default

(note that the use of .qmail+fwd-default rather than .qmail-fwd-default
stops others from using this mechanism to use you as a relay)
