[Gllug] FQDN for local mail relay?

[Garry Heaton]

I've just setup an office mailserver using CentOS 4.3, Postfix, Dovecot,
Fetchmail and SAMBA. The server has the address 192.168.1.254 and the
hostname format is 'robinson.local'. The server is configured to relay outbound
mail to BT's mailserver using Postfix's 'relayhost' setting but although the
Postfix logs show everything relayed to BT successfully with 250 some test
emails have yet to arrive after 5 hours and I'm wondering whether using the
hostname format '<machine_name>.local' is giving mailservers cause for
concern. Is this a FQDN issue? The company has a domain but isn't using it
to host it's own public mailserver, opting for Fetchmail retrieval combined
with a local IMAP server, Dovecot.

Here's the header from the one message I received successfully form my home
email account sent from the office via the server's relay:
