postfix with procmail

I'm trying to set up an e-mail server, but after installing procmail, I can't get it to work.
This is what I get when I try to send an e-mail within the domain:

root: vinci

Not 100% certain about this one, but in a tutorial I'm reading it says that procmail works only if all root e-mail is redirect to a real user.

The best tutorial I've found on procmail is this one: http://userpages.umbc.edu/~ian/procmail.html

It's old, but it's well-written and clearly explained and, based on my personal experience, works for my personal use of Mutt for email.

Could you post the beginning of your .procmailrc file, the part up to when the procmail recipes start?

Did you also install formmail? I'm hardly a Linux postmaster, but I know that, in my .procmailrc file, I have to tell it where to find formmail, but I don't know enough to explain how they work together.

I've never heard of formmail, but that's quite irrelevant, given this is the first time I've configured an e-mail server. In the tutorial I'm reading, which is quite comprehensive, it says nothing of formmail. I'm using SpamAssassin which I gather does the same thing? What I'm trying to say is that I'm not really sure that procmail is dependent on formmail :)

For some reason, it started working. I've no idea why. It might be that I have forgotten to restart the services. This could have been one of the problems. So there's no need for formmail. At least this is what I'm inferring now.

Thanks for the answer, anyway.

Glad it's working and sorry I missed the mark. It was sort of shot in the dark any way.

Could you post a link to the tutorial you were following? Others might find it interesting. I know I would.

Frankly, I'm not that clear on the relationship between formail and procmail, as it's been a while since I first set up Mutt. From what I remember, procmail said where the mail should go and formmail put it there in the correct format. It's not really analogous to Spam Assassin, as it doesn't assassinate anything:). But, as I said, I'm hardly a Linux postmaster.

Formail's man page says

Quote:

formail is a filter that can be used to force mail into mailbox format, perform `From' escaping, generate auto-replying headers, do simple header munging/extracting or split up a mailbox/digest/articles file. The mail/mail-box/article contents will be expected on stdin.

Based on that, formail seems to be more about format than anything else, and, thanks to you, I've learned something new tonight!

Well, it's more of a book than a tutorial, actually.
It's called Pro Linux System Administrator, by James Turnball, Peter Lieverdink and Dennis Matotek. (apress). It's 2009, and I'm implementing it for Centos 7, which means that I have to adapt a few things, but it's not all that bad.
