[Koha] Issue with email configuration_not able to send email to patron

[Library biet]

Hi,
This is Shashikiran M working as Asst Librarian, I installed KOHA live DVD
on my new system and then it was updated to KOHA 19.05 at that time i'm
able to send email to patron, after that I took backup from my old system
and restored into the new system (PC) after restoring the database into the
new system I'm not able to send email to Patron. Can you please help me out.

Thanks and regards
Shashikiran M
