Lots and Lots of Sendmail Configuration Questions
I want to setup a sendmail SMTP server.
but I have a small problem.
I have no idea how to set this up.
I did read some readme files and well I decided Id give up and go to use Webmin for my Sendmail configuration.
Well, ok, webmin is installed and Sendmail is.
Now Webmin asks me to set the M4 Base and Config Directory.
So I set Base to /usr/share/sendmail-cf and the config to /usr/share/sendmail-cf/cf
But that is apparently wrong. But ok, keep that in mind now I want to do something else. Lets say I want to store the emails in the Directory /mail/$USER since Dovecot (My Imap Server) is looking there for emails. So to what folder do I have to set the "User Mail file location". Do I really have to make a Unix User account (so one that is in the /etc/passwd and /etc/shadow files) for every user? Since that looks Mayor unsafe to me?
Also I wonder, is there a easy way to make send a Notification Email when a new email came in the Sendmail box of user X? and another Notification Email to another person if it gets in Sendmail box for user Y? I dont want a forward, I want to send a Notification email. Also I wonder, is Sendmail save?
Since with Telnet you can login and do VRFY to check if a user exists? That looks like a Danger to me.
So, as you see I have a lot of Questions about Sendmail.
And my problem is, I don't have much time left this all has to be setup within a day of 3~4.... And since of my Dyslexia I am not able to read a Thick Manual that Quick. I did read some Manuals and Howtos and FAQs but. I didnt get answers on my questions in them.
So, now I wonder, is there anyone around here who can help me?

You have to watch out with all those tutorials what version they are for as the content of those config files and the like constantly changes.
Also, the syntax is really not intuitive for me and I am always struggling with this. You always have to compile your config files with a special sendmail configuration program. You cannot simply change the ASCII files.
Is this mail server intended only to handle mail on your PC (as with me) or is it on a network handling mail for various PCs or is it even a real mail server in the naive sense of the term? That makes always a huge difference.
Really safe is no program. I guess generally people say now that sendmail isn't the safest anymore but I don't bother.
This VRFY feature is disabled with most mail servers and you can do so as well.
I spend lots of time configuring this sendmail mostly years ago and on FreeBSD boxes. What I have done is I fetch mail with fetchmail onto my PC. Sendmail handles to fill the PC's mail queue and sends mail off to other users internally and over the Internet.
A year or two ago I needed to add a so-called "smart host" as more and more of the most important mail hosters discarded mail sent from IP addresses from ISPs where the IP range can be identified as a dial-in home user account.
Even this last task took me a day or two and worked fortunately from the beginning. So my guess is there is no simple answer to your questions.
I can only advise to get some good instructions from a Web search (there are a few for the plethora of tasks that exists) and watch out that they cover the same version of your sendmail.Bus Error: Passengers dumped. Hech gap yo'q.
So, well naive sense of the term
And, well I thought of a way to Notify the User. so I guess that should be alright.
I hope I can find a Quick Documention.
Since the Official one doesn't make sense to me..
