Email problems with timers

Server Code Codeless

Hello

I’ve set up timers to poll users and send emails to them based on certain conditions.

A high portion of the emails are failing to send, and I get the following error

This is a notification to inform you about the error by your application.The information about the error can be found below.

Application name: Mina_landing
Application ID: XXXXX
Message: Error occurred during template-based email sending. Subject ‘welcome to mina’. Recipients [[xxx)]. Email template ‘xxx’
Exception: Couldn’t connect to host, port: smtp.livemail.co.uk, 587; timeout 10000

Thank you for using Backendless!

Some emails are being sent, so I know this works in theory. Any ideas why so many are failing with this same error?

Hello @Luc_Zentar,

The error message indicates that it was not possible to connect to the mail service you specified.
Could not connect to host, port: smtp.livemail.co.uk, 587; timeout 10000

Contact your SMTP service provider to resolve this issue.
