Dear Administrator,

Thank you for your email.

We regret to inform you that we are not able to accede to your request. We do not whitelist IP addresses or domain hosts at server level, as this process could render the servers vulnerable to possible abuse. May we suggest that you advise the relevant party (rca.com@pacific.net.sg) to do the whitelisting on his end should he wishes to receive mailers from you.

Please email us if you have further queries on this matter.

At your service,

Postmaster
PACNET
