[imp] Virtual hosting questions..

[Chad Day]

Thanks, Magnus.

What I decided on doing was something like this:

When I create a user, in another associated application I am running, they
are assigned a user ID #, so when I create the mail user, I just do
something like:

jsmith_userid#

and then alias jsmith@virtdomain.com to jsmith_userid#

Of course, that only works for incoming mail.. and they still have to sign
in with jsmith_userid# when they are logging into IMP.  Is there a way I can
have them sign in on their virtual domain with jsmith, and have it look up
the appropriate mailbox?  Also, like I said I know the alias only works for
incoming, so when they try to send mail it's going to be jsmith_userid#,
instead of jsmith.. I saw in the archives that I should try enabling
genericstable in my sendmail.mc file, but my problem is I *have* no
sendmail.mc file on my server.. it was already built, I didn't do it from
scratch (it's v8.11.0).  I know this is an offtopic question, but does
anyone have any ideas on what to do?  Should I try grabbing a generic
v8.11.0 sendmail.mc file, plugging it in, and enabling genericstable?

As for storing the information in a database, yeah, I probably should.. but
I have enough to tackle right now I think.  I'll worry about that later. :)

Thanks,
Chad

If you have one mailservet whith multiple virtual domains, i recomend yo
to have virtual aliases for everyone, exept your own domain.

then you can set jsmith@blaha.com   --> bc1234
		jsmith@lalala.net   --> bc1235

and so on.

if you hope on a big site, i also recomend you to store the userinfo in
some kind of sql database, mysql for example.

Then it is easier to maintain.

the user then can only log in with his own account.
