Building, Compiling, M4 Sendmail

[sproosy]

OK I have just downloaded the newest version of sendmail.
I performed a ./Build
Now i need to add a few m4 features to a MC file to make my sendmail.cf file.
How do i add the features, and then create the sendmail.cf file. Hwere are all of these OS Specific files kept. I have read some documentation on the web and its given me bits of info here and there but not the full idea of what to do???

Please help!? Thanks Sproosy MCP

Keep it real!

You should have a /etc/mail/sendmail.mc. If not look in /usr/share/sendmail-cf/cf and look for a .mc file that looks like it is for your system. If not, choose a generic one and copy it to /etc/mail/sendmail.mc. It doesn't have to be called sendmail.mc but it helps to explain things if I do it that way. Open it up in a text editor and do your thing. For some help with this, look at /usr/share/sendmail-cf/README. When you are done, you need to compile it to create sendmail.cf. Use the following command:

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

Some distros have sendmail.cf in /etc/ so your paths may be different from what I have here.

Nice! Ok next i want the server to be able to que mail for users so they can log in remotly with a mail client and receive their mail, also make the server relay any non internal mail to the outside world and masquerade. What m4 Features do i need to add to the mc file?

thanks dudes! Sproosy MCP

FEATURE(`relay_local_from')dnl

Note: the mark just before the word "relay" is the back tick under the ~, not the one under ".

Open /etc/access (/etc/mail/access on some systems).

You will see something like this:

127.0.0.1 Relay
localhost Relay

Add your domain to the list:

yourdomain.com Relay

Now you need to create access.db

makemap hash /etc/mail/access.db < /etc/mail/access

Most distros come with a pop3 server. It will be called pop3d or something. It runs as a daemon so you'll need to make sure xinet.d starts at bootup also.

I am assuming you have DNS setup for mail. If not you need to create an &quot;A&quot; record for mail.yourdomain.com and point it to your ip. Then you need to create an &quot;MX&quot; record for it showing mail.yourdomain.com handles the mail for yourdomain.com. That's it. Now your users can setup an account in OutLook or other mail client. They would use mail.yourdomain.com for both the pop3 and smtp servers. They would use the same user name and password that exists on your system.

Dude i understand the steps you have told me to do but there is no /etc/mail/access

if i create the directorys/files will it work??

Take a peek inside sendmail.mc and look for a line that starts with FEATURE(`access_db'... This will tell you the path where sendmail looks for access.db. If it's there, then create access in that directory. Some distros have it in /etc/.

 

[sproosy]

the mc file that i made doesnt have that line in it. If i just add it to the .mc file, recompile and create the files will it be ok?

Thanks heaps! Sproosy MCP

Keep it real!

Here is a copy of my sendmail.mc. All my users can send and receive mail remotely through my server. You can copy and paste the whole thing or just use the lines that are missing on yours. Good luck.

thanks dude ill let you know how i go!!! Sproosy MCP

Keep it real!

 

[sproosy]

Ok one last question do you also use this server to relay any non-local mail onto the www? Sproosy MCP

Keep it real!

 

[RhythmAce]

Yes - that's what relaying is. It allows mail to pass through your server.
