POP3Domain

Explanation:

Specifies the name of the Internet domain to use as the gateway to send mail to

the Internet for local addresses. (All local addresses are converted to

Internet addresses.) If this setting is included in NOTES.INI, it overrides

the DNS value.

Configuring the Internet Domain Suffix for the IMAP and POP3 Servers

Problem:

After reading the following section of the Domino 4.6 Release Notes, a customer

would like an explanation of how a Notes user's repliable address is formed

when retrieved via IMAP/POP3.

Configuring the Internet Domain Suffix for the IMAP and POP3 servers.

When you use an IMAP or POP3 client to retrieve messages delivered to you

through the Internet, the Domino server appends the fully-qualified domain name

(or domain name only) of your server to form a standard Internet mail address.

For example, if a user's mail address in Notes is "Jane Smith" and Jane's

Domino server is deployed on a machine named "sales.acme.com," the email

address is represented as "Jane_Smith@sales.acme.com" in the Internet mail

client. This makes it possible to reply to the sender without further typing

of the Internet address.

The system administrator can configure a server configuration variable to

control the value of the domain name part of the Internet mail address, also

referred to as the Internet domain suffix. For IMAP, set the InternetDomain=

variable to be the fully-qualified domain name (or domain name only).

For

example, "InternetDomain=sales.acme.com." For POP3, the variable is called

"POP3Domain."

If the values for these variables are not supplied, the server checks the

Global Domain documents in the Public Address Book and determines if there is a

Global Domain document that is selected as the default global domain(see

attached bitmap image). If a default global domain is found, the first name

listed in the Internet domain suffix field is used to form the Internet

address.

Note: If only one Global Domain document exists, the first name listed in the

Internet domain suffix field is used.) If the fully-qualified domain name is

not specified in the Global Domain document, the server checks the TCP stack

for the host machine's domain suffix (domain name only, host not included).

Finally, if no domain name can be determined, the server supplies the value

"NoDomain."

Solution:

The following is an explanation of how a Notes user's repliable address is

formed when retrieved via IMAP/POP3.

The Notes user's repliable address is built from an INI variable, if present.

Then it checks for a default Global Domain, and checks the fully qualified

domain name at the stack.

With no INI variable or default Global Domain specified, the repliable Notes

address might look like this:

Joe_User/Org1/Org@acme.com

When the POP3 client replies to this user, the following processes take place:

An inbound session to the SMTP MTA from the POP3/IMAP client would be

established. The MTA would convert the message and check the Internet Domain

Suffix. If the Internet Domain Suffix was listed in the Global Domain document

(in the Internet Domain Suffix field), the message would be accepted for local

delivery. If the Internet Domain Suffix was not listed , the message would be

sent back out to the Internet to deliver the mail to the recipient.

With a default Global Domain specified, the first entry in the Internet Domain

Suffix field would be used in the formation of the Notes user's repliable

address.

No NOTES.INI variable but a default Global Domain specified, the Notes user's

address would look like this:

(Internet Domain Suffix field in the Global Domain = pop3.domain.com)

Joe_User/Org1/Org@pop3.domain.com

With the pop3domain= NOTES.INI variable enabled , the Notes user repliable

address would be formed using this variable. No default Global Domain but the

NOTES.INI variable is enabled, the address would look like this:

(pop3domain=pop3.company.com)

Joe_User/Org1/Org@pop3.company.com

Applies to:

Servers

Default Value:

None

UI equivalent:

None, although you can specify this setting in the NOTES.INI Settings tab of the Configuration Settings document in the Domino Directory.

Syntax:

POP3_Domain=Domain
