Leaving it open to accept email from other sources leaves your mail server exposed to an attack and limits the effectiveness of SpamTitan Cloud. If you are an Office 365 customer, see Locking down your Office 365 mail server. IMPORTANT The IP addresses below are for new SpamTitan Cloud customers completing their initial setup. If you are an existing customer, you may be using different IP addresses. See SpamTitan Cloud Server IP Addresses for more information. Set up your email server to only accept mail from the following FQDN IP addresses: * cloudv.spamtitan.com ( 18.188.207.172 ) * cloudw.spamtitan.com ( 18.190.56.214 ) * cloudx.spamtitan.com ( 18.216.101.235 ) -------------------------------------------------------------------------------- Did you find it helpful?
