When the libcom.org server sends mail, it uses the HELO string of "libcom". This really should instead be "libcom.org" -- the name of the host that is actually sending the mail -- to avoid triggering anti-spam filters.
As a guess, you have `hostname` set to "libcom" on the server, and your software is picking that up by default. At least on the unix flavors I use, the fashion these days is to set the `hostname` to the FQDN.
may well be fixed now and yes that was it I think. Thanks AP! When we set this up we knew absolutely nothing about it whatsoever.

Still seems broken. From mail sent just now:
"EHLO libcom"
catch.
hmm. well I changed /etc/hostname and restarted mail
What mail system are you using?
exim4 - it's only there for sending php mail though, not running as a mailserver proper. Which might be why this is messed up - just got phpmail working and left it, I don't really understand e-mail stuff very well.
Probably quite important to get this going with the forward module now.
yeah plus lost password e-mails etc. should be easy to fix - must be set somewhere other than /etc/hostname like mail config itself.
something like dpkg-reconfigure exim4 should bring up basic setup again. might be as simple as going through that.
Well if we can't figure it and AP doesn't pop up here again we could always drop him/her an email.
Sorry I disappeared -- yes, the reason I noticed was that I couldn't sign up, because I didn't get the initial confirmation email.
About /etc/hostname: the kernel usually has an idea of its hostname, and this is usually set at boot time from some config file, in your case /etc/hostname I guess. If exim is getting its hostname from the kernel, then you'd need to explicitly set the hostname with the `hostname` command, and maybe restart exim, to change it before the next reboot.
I haven't posted here because I haven't taken the time to look into the exim4 docs to try to find out where the EHLO string comes from. I'll try to get to it today, but I can't promise anything. I haven't used exim4 myself before; I use postfix on my machines.
Oh, and male pronouns are fine.
was playing around with postfix when thinking about setting up proper mail server on here, but I got fed up and realised it'd be safer to use something else than risk losing e-mails for ages when it went wrong so reverted to exim just 'cos it was default, seems a lot lighter though.
I believe I found the config param: helo_data.

It defaults to $primary_hostname.
"The value of this option is expanded, and used as the argument for the EHLO, HELO, or LHLO command that starts the outgoing SMTP or LMTP session. The variables $host and $host_address are set to the identity of the remote host, and can be used to generate different values for different servers."
And primary_hostname defaults to the value from uname:
http://www.exim-new-users.co.uk/content/view/39/39/
and on NetBSD at least, `uname -n` is the same as `hostname`.
So I think this suggests that running `hostname libcom.org`, followed by restarting exim, will solve the problem.
Thanks AP!
I've done that, hopefully that'll fix it!
