How POP Rebuilds the OpenVMS Mail From: Field
The most important message header is the
From:
header because it can be used as
a destination address if a reply is requested from the POP client. Therefore, the
POP server rebuilds the OpenVMS Mail
From:
field in compliance with RFC 822
before sending the header to the POP client.
Table
6–3 describes the types of addresses that can appear in the OpenVMS Mail
From
:
field.
Table 6–3: OpenVMS Address Types
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 described in the Compaq TCP/IP Services for OpenVMS Management guide,
make sure you test the configuration carefully with your POP client systems.
If the logical name TCPIP$POP_IGNORE_MAIL11_HEADERS is defined and
theaddressisanSMTPaddress,therebuilt
From:
field is not displayed to the
user. In this case, the POP server sends the actual headers from the body of the
mail as the mail headers.
