I installed a mail server recently (dovecot/postfix), that checks for the
HELO message.

I wasn't able to send any mail from Outlook.
The problem beeing that Outlook send its hostname as HELO message...


r...@mephibox : tail -f /var/log/mail.log
[..]
# starting outlook
Dec 1 21:34:12 localhost dovecot: imap-login: Login: user=<faust>,
method=PLAIN, rip=my_ip, lip=srv_ip
Dec 1 21:34:13 localhost dovecot: IMAP(faust): Disconnected in IDLE
Dec 1 21:34:13 localhost dovecot: imap-login: Login: user=<faust>,
method=PLAIN, rip=my_ip, lip=srv_ip
Dec 1 21:34:14 localhost dovecot: IMAP(faust): Disconnected in IDLE


# sending mail
Dec 1 21:34:44 localhost postfix/smtpd[11381]: connect from ma_box[my_ip]
Dec 1 21:34:44 localhost postfix/smtpd[11381]: NOQUEUE: reject: RCPT from
ma_box[my_ip]: 504 5.5.2 <beta>: Helo command rejected: need fully-qualified
hostname; from=<fa...@example.com> to=<faus...@other.example.com> proto=SMTP
helo=<beta>
Dec 1 21:34:44 localhost postfix/smtpd[11381]: disconnect from ma_box[my_ip]


beta beeing my WinXP client's hostname

I tried to change my hostname to beta.example.com, but windows keeps saying
I can't put dots in this field...
Then, I checked the 'Domain' option (instead of 'Workgroup'), typed my
domain name, tryied to connect ...
Checking the error details, the main idea was that there wasn't any ldap
record in my DNS (which is wrong, there's just no LDAP at that address).

It ended up that there's no way I would setup any LDAP server to provide
mail services to my VMs.


So... back to your problem, first thing to check: are you member of your
mail server's domain? Did IT correctly configured your computer/Are you
trying from your own laptop?
Even if you can send mail to other members of your domain or a large part of
mail servers (mostly based on exchange, poorly configured postfix, ...): I
won't be surprise if Exchange isn't checking the HELO message...
