hey friends,
I have installed sendmail or it would rather say it comes default with
the
centos. I am using Centos4.0 and I am trying to configure sendmail
with virtual users.
I have created few users for my domain. My internal domain
(example.com) is
different from my isp domain (example1.com).
The problem I am facing is that if the user1@xxxxxxxxxxxx sends the
mail to
the user2@xxxxxxxxxxxx then the mails should not go to the ISP rather the
server running sendmail should send it to the mailbox of the
user2@xxxxxxxxxxxx but rather it is sending it to the ISP account and
from
there it is getting redirected to ther user2 mailbox.
Mail coming from your ISP for domain exampl1.com isn't rejected? Can it
be that you fetchmail the mail?
I ask because I bet you did not configure example1.com to be in class{w}
(means treated to be local). Do so by adding that domain to
/etc/mail/local-host-names. That is a plaintext flat file. Sendmail
daemon restart is necessary.
I have configured the virtualusertable like this
user1@xxxxxxxxxxxx user1(local account)
user2@xxxxxxxxxxx user2(local account)
makemap hash virtualusertable.db < virtualusertable
service sendmail reload/restart.
If you "service sendmail restart", then changes to map files are
detected automatically and a "make -C /etc/mail" is run automatically to
rebuild the hashed map files, the .cf files to if changes to .mc files
happened.
Now if the mail for the user2 from the user1 the sendmail should
forward it
to the user2 mailbox but this is not happening rather sendmail is
forwarding
it to the ISP server and from there it is gettting move to the user2
mailbox.
For local domains neither the smarthost nor mailertable will be used.
echo '$=w' | /usr/lib/sendmail -bt
Prints you out all class{w} domains.
Second problem I am facing is that how do I configured sendmail to the
send
the credentials of each user to the ISP account. For example if user1
wants
to send the mail to the Internet the sendmail server should connect to
ther
ISP server with this user credentails (username and password ) and if
user2
wants to send the mail to ther Internet then the sendmail should
connect to
the ISP server with the user2 credentails ( username and password).

It isn't possible to define multiple users for a single relay host target.
(With Postfix you would require release 2.3)
For different relay selections based on the sender there is
http://anfi.homeunix.net/sendmail/smarttab.html
I have about 25 user accounts and I using sendmail 8.1.13 version.
Please let me know if you need any further inputs.
Thanks & Regards
