Abstract

An integer value (0, 1, or 2) that determines whether or not LISTSERV sorts the recipient list in outgoing SMTP jobs.


Example

z/VM:

SORT_RECIPIENTS = 1

Unix:

SORT_RECIPIENTS=1

export SORT_RECIPIENTS

Windows:

SORT_RECIPIENTS=1


Details

This is an optimization parameter that you would normally set through the Optimization Settings tab in the web administration interface.

SORT_RECIPIENTS should be set to 1 for best performance if your mail delivery host is a unix machine. Other systems do not normally need a pre-sorted recipient list for optimal performance.

If this variable is set to the value 2, LISTSERV will not sort the recipient list if the number of recipients is less than or equal to your MAXBSMTP setting. Conversely, for jobs where the number of recipients is greater than MAXBSMTP, LISTSERV will sort the recipient list (keeping XYZ.COM together and thereby conserving resources). Note, however, that this enhancement was useful only with L-Soft's legacy LSMTP mailer, and should not be used if you are using any other MTA for LISTSERV's outbound mail.

SORT_RECIPIENTS is ignored when sending mail-merge messages, as each outbound SMTP message contains only a single recipient.


Default Value

0
