Cant send mail from Evolution or Squirrel Mail

[bazza]

Hi Folks, a little help is needed. I have ISPC3 installed on Debian Lenny using Falko's perfect guide (btw thanks for that). I'm playing with this locally with server as 192.168.1.10, DNS192.168.1.54 and ...55
I find that I can't send e-mails (although I can connect to the mailbox and retrieve mail)
When I try sending a message locally I get this in the logs

Jun 16 11:03:52 joey postfix/smtpd[18950]: disconnect from unknown[192.168.1.10]
Jun 16 11:03:52 joey postfix/smtpd[18950]: connect from unknown[192.168.1.10]

And when I try to send a message externally>>>>>>>>>>>>>
Connection to the server is refused and I get this in the log.
Jun 16 11:04:11 joey postfix/smtpd[18950]: connect from unknown[192.168.1.10]
Jun 16 11:04:11 joey pop3d: Connection, ip=[::ffff:192.168.1.10]

I think I know how to fix this (I've got a bit of experience with Sendmail but I'm new to Postfix) but the first problem has me stumped.

Please check if amavisd is running.
Port 10024 is amavisd and it seems that your postfix cannot connect to amavisd.

[bazza]

You where correct. I checked and it was not running. Firing it up from the command line we got:-

joey:~# /etc/init.d/amavis start
Starting amavisd: hostname: Unknown host
The value of variable $myhostname is "", but should have been
a fully qualified domain name; perhaps uname(3) did not provide such.
You must explicitly assign a FQDN of this host to variable $myhostname
in /etc/amavis/conf.d/05-node_id, or fix what uname(3) provides as a host's
network name!
(failed).
joey:~# uname -a
Linux joey.xxxx.co.nz 2.6.26-2-686 #1 SMP Thu May 28 15:39:35 UTC 2009 i686 GNU/Linux

Supplied the required data and it now works. Still a bit puzzled as to why it didn't work previously as uname had the correct FQDN.

Thanks for your help:)
