Greetings,
I've been wrestling with postfix for years, and I still can't get it to act as 
the final destination of all incoming mail. Mail from the Internet is fine, but 
mail originating on the LAN is always forwarded to the user's own machine.
(Dovecot then serves IMAP on request to KMail on my desktop machine.)
Here is the relevant content of my latest main.cf:
$ cat main.cf
mynetworks_style = host
relay_domains = 
home_mailbox = .maildir/
Can anyone suggest something else I can try?
-- 
Regards,
Peter.

The mail thing is very confusing, but here is some main.cf settings on my machine that receives mail from the other machines on the LAN: inet_interfaces = $myhostname, localhost mydestination = $myhostname, localhost.$mydomain, localhost, <my local hostname> <- the simple name, not the hostname.lan that I've set in 'myhostname' mynetworks = 192.168.0.0/24, 127.0.0.0/8 Hope that helps, Arve ^ permalink raw reply [flat|nested] 17+ messages in thread

So your dovecot gives user mails to your postfix and you expect that him relay out. If postfix has not smtp service it can't rely mail out since it has, with TURN smtp command, change from smtpd server to smtp client to connect to externals smtpd server IMHO. I think this is the reason because you outgoing mail gets inbound mail, because postfix can't act as smtp client and only server one.

It just hit me that given the problem, maybe there was a problem related to the recent changes in Dovecot files. I've been known to miss a news item in the past myself. I'm sure others have too.

Last year I had to sent several hundred of them.... Prior mounting one mail server it's needed to read a bit about postfix, the smtp conversation restrictions are critical and is needed to master them, a lot of them are DNS related too so, is required also master DNS service. The restrictions are like a firewall. Also it's needed that the mail admin is able to make connections to his smtpd port through openssl for example by submission service (I suppose that at least got implemented starttls and sasl forbidding clear text AUTH). Also one mail admin can't mount smtpd servers through "kitchen receipts" At least the EHLO, MAIL FROM, RCPT TO, DATA, AUTH, STARTTLS, and some other that are secure relevant as VRFY, ETRN etc sould be mastered. prior putting the server in contact to internet and the mail admin have to test it locally, for example, that AUTH command is required to be wrapped under TLS and that no one can send mails without AUTH. Also mail admin should avoid the mail from forgery. The master.cf sent indicates that no services got chrooted and priv dropped which is a very bad idea. Almost all services can (and should) be chrooted and almost all can drop privileges (and should). The first thing I usually do is delete permit_mynetworks (and probably I'm not alone in this) from smtp restrictions. The reality about the problem is that we can't know what's happened because we have not data to investigate further, no tests to mail server to see what's happened, with server codes after smtpd conversation, no logs, also if mail admin doesn't know how dovecot and postfix interacts between them cant debug it and by this reason we can't know if it's a dovecot trouble, a DNS trouble or one postfix trouble.....

You must test your mail server using openssl command directly (I expect that you use TLS AUTH at least), do the full SMTP conversation with your server, EHLO, STARTTLS, AUTH, MAIL FROM, RCPT TO, DATA. All of them and check status codes. this interaction will give you info useful to find the trouble.
