Hi
Mails from vCenter are being rejected by the SMTP server due to the helo command:
(hostnames and addresses changed)
220 mailserver ESMTP Postfix (Ubuntu)
HELO spvcenter
250 mailserver.domain.ch
MAIL FROM: <vCenter@customer.domain>
250 2.1.0 Ok
RCPT TO: <customermail@customer.domain>
504 5.5.2 <spvcenter>: Helo command rejected: need fully-qualified hostname
QUIT
221 2.0.0 Bye
vCenter is using just the hostname, instead of the FQDN !
is there a way to change the helo command? I didn't find anything on the KB...
unfortunatelly, we don't have the possibility to configure the mailservers whitelist.
thanks!
Doomi
