Hey Guys, I've had a production system in place for a few years now with no issues. Lately the system hasn't been sending email reports / notifications etc.
I've checked the log and found the following...
WARN 2018-04-09 11:45:43,852 (com.serotonin.m2m2.rt.maint.work.EmailWorkItem.execute:86) - Error sending email
org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: in-v3.mailjet.com, port: 465, response: -1. Failed messages: javax.mail.MessagingException: Could not connect to SMTP host: in-v3.mailjet.com, port: 465, response: -1; message exception details (1) are:
Failed message 1:
javax.mail.MessagingException: Could not connect to SMTP host: in-v3.mailjet.com, port: 465, response: -1
I've tried the other ports such as 25, 587 TLS on/off etc, and all the same errors.
I can ping the hosts, I've also tried just IP Address.
Maybe something is not working with the way Java connects to these hosts?
Cheers
Dan
