I need help setting up sendmail for only internal delivery. Im using a webserver and one of the php scripts sends out an email. I need to send email to some user at this internal address such as joeuser@testwerks.com.

say i want to have a webserver that is internal to my network (behind a router & firewall) and i want to use a name like testwerks.com and resolve to an internal ip address. so can i set something like this in /etc/hosts
192.168.2.xxx testserver.com

what sendmail changes do i need ?

If I understand your post correctly, you're NOT going to setup a DNS server. If thats the case, then you will probably want to use sendmails mailertable feature to establish an MX record for your domain.

1) edit /etc/mail/mailertable and add:
mydomain.com esmtp:[mail.mydomain.com]

2) add mail.mydomain.com to /etc/hosts file

3) Rebuild mailertable database
# cd /etc/mail
# make

4) test

ok, im getting closer, but still not there as no mail is showing up when i log in as the user who is supposed to be gettign the mail. ive done what you mentioned above with the only difference is that im using billybob.swerks.com instead of mail.swerks.com

/etc/mail/mailertable
swerks.com esmtp:[billybob.swerks.com]

/etc/hosts
127.0.0.1 localhost.localdomain localhost
127.0.0.1 billybob.swerks.com billybob

then i send a mail to a user cust1
mail -s "test cust1" cust1@swerks.com "hello cust1"


when i send a mail to a user such as cust1, the log in as cust1 i never get the the mail, then when i look at maillog i see these lines
Apr 7 11:27:59 billybob sendmail[11954]: j37GRwHl011954: from=root, size=56, class=0, nrcpts=3, msgid=<200504071627.j37GRwHl011954@billybob.swerks.com>, relay=root@localhost

well, i had to reinstall sendmail because i had hosed up my sendmail.mc file and didnt back it up like a doofus. let this be a lesson - always backup a config file (esp sendmail stuff) before monkeying with it




after re-installing sendmail to get my original sendmail.mc file back, i made the change to my mailertable file and wha-la, im sending mail to users at my fake/internal domain name

yaaaay!

i can send mail from a shell, but not via apache / php. the maillog shows the mail as being sent, but when i log in as that user, the mail isnt there
