But how he was able to do so

Local Server Email will not send

Hi Dmitriy I had figure out the problem, I switch another mail server use normally smtp protocol with 25 port, then the mail system is working correctly. after I switch back and use smtp with 25 port and set mail.smtp.starttls.enable=false every mail was sent immediately. Like you said maybe this mail server need some additional options or other parameters. Sending mail is an important procedure in blynk I purpose add more parameters in it
