configure sendmail to accept all mails from specified host (including marked spamsrv)
how can i configure sendmail to accept all mails from specified hosts, even if they are marked as spamservers (at spamhaus.org for example).
our company has lost some important mails that were sent from a sister company in another country because their server was listed at sbl-xbl.spamhaus.org.
is there a possibility to configure sendmail to accept the messages sent from that host even if the server is listed in a spamlist?
if you need more information do not hesitate to contact me.
thank you all for the help.
