Configuring and Managing the POP Server
18.3 Modifying POP Server Characteristics
Table 18–2 (Cont.) POP Logical Names
Logical Name Description
TCPIP$POP_MESSAGE_MAXIMUM n Defines the maximum number of mail messages that a
single client can download per connection, where n is a
number from 0 to 65,535. If not defined, the POP server
uses the default value of 0 (no maximum).
TCPIP$POP_LINK_IDLE_TIMEOUT n Determines the length of time the server allows a link to a
POP client to remain idle, where n is a number specified in
OpenVMS delta time delimited by quotation marks. A POP
link remains active until it is released by the POP client.
If not defined, the POP server does not set a link idle value
(0 00:00:00.00).
TCPIP$POP_PERSONAL_NAME If defined, the POP server provides the POP clients with
the message header
From: fields that include the sender’s
personal name, if one appeared in the sender’s
From: field.
TCPIP$POP_LEAVE_IN_NEWMAIL If defined, mail that has been read by the PC client but not
deleted remains in the NEWMAIL folder. Allows users to
access mail from different systems and determine when to
move or delete the mail from the POP server. If not defined,
mail that has been read but not deleted is moved to the
MAIL folder.
TCPIP$POP_USE_MAIL_FOLDER If defined, moves all mail to the MAIL folder and displays
this folder instead of the NEWMAIL folder.
TCPIP$POP_FAST_SCAN If defined, the POP server estimates the number of bytes for
the size of the mail message based on the number of lines in
the message instead of counting the exact number of bytes.
Setting this logical may improve performance.
TCPIP$POP_MAXIMUM_THREADS Allows you to define the number of process threads that
POP can activate. The default is 15. If you set this logical
to 1, the POP server becomes single threaded. This logical
is recommended only as a temporary solution to system
resource problems.
TCPIP$POP_IGNORE_MAIL11_HEADERS If defined, the POP server ignores the OpenVMS message
headers when mail is sent from SMTP, which contains an
SMTP address in the
From: field. For information about
how POP forms message headers, see Section 18.1.6.
TCPIP$POP_SEND_ID_HEADERS If defined, the POP server sends
X-POP3-Server and
X-POP3-ID headers for each mail message. If not defined,
the ID headers are not sent for any mail from an SMTP
address. For information about how POP handles message
headers, see Section 18.1.6.
