EMBEDDED_MAIL_MERGE
Platforms
All
Abstract
A Boolean value determining whether LISTSERV writes individual mail-merge messages to its spool, or uses BSMTP to offload the creation of the individual messages to an external server. With this value set to 1, any high-capacity SMTP server can be used to deliver LISTSERV e-mail that uses mail-merge.
Embedded Mail Merge is enabled by default.
Example
z/VM: |
EMBEDDED_MAIL_MERGE = 1 |
Unix: |
EMBEDDED_MAIL_MERGE=1 export EMBEDDED_MAIL_MERGE |
Windows: |
EMBEDDED_MAIL_MERGE=1 |
Details
Embedded mail-merge is a "brute-force" method. In this mode, each individual merged message is written to LISTSERV's spool as a single-recipient MAIL file. In turn, each individual MAIL file is then delivered by SMTP to the outbound SMTP_FORWARD host.
Since Batch SMTP (BSMTP) cannot be used in the embedded mode, sites with very high volumes of mail may wish to split the load across multiple outbound mail servers using SMTP "workers" (defined with SMTP_FORWARD_n variable settings in the site configuration file). In addition, DISTRIBUTE "workers" can be used in very high volume situations to move mail smoothly.

History: Embedded mail-merge was introduced to end dependence on L-Soft's discontinued and no longer supported LSMTP product. Please, if you are still using LSMTP, find another SMTP product. |
Default Value
1 (that is, enabled)
