Configuring and Managing the POP Server
18.1 Key Concepts
Address Type Address Format
SMTP SMTP%"legal-address," where legal-address is an
address that is compliant with RFC 822 and is
commonly in the user@domain format
DECnet node::username
User name username
DECnet address within quotation
marks
node::"user@host"
Cluster-forwarding SMTP address node::SMTP%"user@domain"
A host name is local if one of the following is true:
• The host name is the same as the substitute domain specified in the SMTP
configuration.
• The host name is found in the TCPIP$SMTP_LOCAL_ALIASES.TXT file.
Some POP client systems are confused by the use of personal names when you
attempt to reply to a mail message or when the name contains commas or other
special characters. If you define the TCPIP$POP_PERSONAL_NAME logical
name outlined in Section 18.3, make sure you test the configuration carefully
with your POP client systems.
The following sections describe how POP rebuilds the message
From:
field for
each type of address.
18.1.6.1.1 SMTP Address The POP server uses the SMTP address within the
quotation marks to rebuild the
From:
field of an SMTP address. For example,
message header
becomes:
SMTP hides nested quotation marks by changing them to cent sign (¢) characters
before passing them to OpenVMS Mail and then changing them back after a
reply. The POP server removes any cent signs that designate double quotation
marks. For example, the following message header:
From: SMTP%"¢ABCMTS::MRGATE::\¢ABCDEF::VIVALDI \¢¢@xyz.org"
Becomes:
From: "ABCMTS::MRGATE::\"ABCDEF::VIVALDI\""@xyz.org"
18.1.6.1.2 DECnet Address The TCPIP$POP_DECNET_REWRITE logical
name values define how the POP server rebuilds a DECnet address, as shown in
the following list:
• GENERIC
The entire address is changed to the SMTP format. For example, from host
widgets.xyzcorp.com
, the message header
From: ORDERS::J_SMITH
becomes:
From: "ORDERS::J_SMITH"@widgets.xyzcorp.com
• NONE
The
From:
line is sent to the POP client unmodified. For example:
From: ORDERS::J_SMITH
You cannot reply to this type of message because the SMTP server does not
accept an address in this form.
