Forum OpenACS Development: Replacing ns_sendmail with acs_mail_lite::send

Emmanuelle sent me this:

"I've grep'd the whole openacs repository tree looking for ocurrence of ns_sendmail to replace those calls with acs_mail_lite::send. I'm done for core and dotlrn except assessment. Here is the list of files where
it's used:

assessment/sql/oracle/assessment-actions-insert.sql
assessment/sql/oracle/assessment-actions-package-create.sql
assessment/sql/oracle/upgrade/upgrade-0.22d3-0.22d4.sql
assessment/sql/postgresql/assessment-actions-create-p.sql
assessment/sql/postgresql/assessment-actions-create.sql
assessment/sql/postgresql/assessment-actions-insert.sql
assessment/sql/postgresql/upgrade/upgrade-0.10d6-0.10d7.sql"

I am not really familiar with this code.

Does anyone know what this feature does, or use this feature in production work that they could add the acs_mail_lite::send calls and test it?
