The database file for POP-before-SMTP is stored in the following way:

Directory
: Temporary directory (Default:
/var/tmp/fsigk
)
File name
:
pbs.db
Key

00:00:00
))
You can check information on the current database by running “

”
and other commands.
Every time a service is restarted, all the information in the database for POP-before-SMTP is deleted.
