Acum reporniti Postfix:

 

/etc/init.d/postfix restart

 

Pentru a verifica daca SMTP-AUTH ?i TSL functioneaza corect rulati urmatoarea comanda:

 

telnet localhost 25

 

Dupa ce conectarea cu serverul dumneavoastra de mail postfix a fost realizata, introduceti

 

ehlo localhost

 

Daca vedeti liniile

 

250-STARTTLS

 

250-AUTH

 

totul este în ordine.

 

Scrieti

 

quit

 

pentru a reveni la linia de comanda.
