Mails to groups being delivered as "bcc"

We have a strange issue in our domain. We have certain groups having external mail address. Say the group is “Test” with address “Test@domain.com”.

When somebody internally sends an email to “Test” or “Test@domain.com”, the mail gets delivered normally. However, when the email is addressed to “Test@domain.com Test@domain.com”(as this is stored in the Local Address Books in some cases), the mail is routed to the SMTP server and then gets delivered to the recipients.

The issue is each of the members of the “Test” group can see that the mail is delivered to them as “bcc” even though it’s not. The “To” and “Cc” lists are maintained as it is, however the members of the group are "bcc"ed.

Can somebody guide me across this? Thanks in advance

The code is checking for a Notes mailing address that has an internet address matching the keyed value. If the lookup is successful and the retrieved contact note is mailing system “1” (Notes mailing system), than the contact’s canonical address is substituted for the internet address. Sever internet addresses are not in rfc822 format.

Subject: Our setup

As mentioned earlier “Test@domain.com” delivers the mail internally as intended without any issue, as the lookup is resolved.

However, in certain cases, addresses like “Test@domain.com Test@domain.com” are added to the recent contacts of users and it’s this format that’s causing the issue
