SMTP Auth Direct
Occasionally, all SMTP certifications may fail with SP5860 006 set to "2" to
enable encryption during SMTP certification for the SMTP server. This can
occur if the SMTP server does not meet RFC standards. In such cases you
can use this SP to set the SMTP certification method directly. However, this
5860 025
SP can be used only after SP5860 003 has been set to "1" (On).
