I have a problem with Courier 0.37 and Debian Woody. I am using all Debian packages associated with Courier. No Exim, no Postfix, no Qmail.

I can send/receive mail only under some weird circumstances but IMAP and authdaemon module work fine. I testing in a LAN. Servername is "bender".

bender:~# testmxlookup futurama Domain futurama: Relay: bender.futurama, Priority: 10, Address: ::ffff:10.0.0.148

Config in etc/courier is like default config, except: locals: futurama hosteddomains: futurama esmtpacceptmailfor.dir/futurama: futurama and .futurama defaultdomain: bender.futurama

Other Config files: etc/hostname: bender.futurama etc/resolv.conf: search futurama and nameserver 10.0.0.148

DNS is working: bender:~# host bender bender.futurama has address 10.0.0.148

Reverse *seems* to be working: bender:~# nslookup -silent 10.0.0.148 Server: 10.0.0.148 Address: 10.0.0.148#53 148.0.0.10.in-addr.arpa name = bender.futurama.

When I'm trying to send mails from root via: sendmail blukas@futurama test ^D the mail gets delivered.

But when I'm trying to send via: telnet localhost 25 HELO bender MAIL FROM:<blukas@futurama> I'm getting a 517 Syntax Error.

ANY mail with a domain containing a "." seems to be accepted by SMTP (but don't delivered if the domain didn't exist, because "postmaster" is aliased to "blukas" and defaultdomain is "futurama" only, so I cannot even receive delivery failure mails, however I can see them in Courier's "bigbrother"-directory (most of them bounced).

Any suggestions are welcome.

Furthermore, am I right that etc/hostname should contain only the name of the host ("bender") and defaultdomain in etc/courer should contain only the domain ("futurama") and not both ("bender.futurama")?
