Hi,

The MX of the domain jimdo.com support STARTTLs but it does not have a certificate configured. You will not be able to send emails to these kind of domains untill you:

• create a new TLS strategy (e.g. ‘no-tls’): in Management->MTA->Outbound->TLS Strategy create a new strategy with STARTTLS disable. In the existent strategies STARTTLS is optional which means if the server is capable will be used. For this kind of servers is impossible because of bad configuration
• use this new strategy: Management->MTA-Outbound->Strategy->TLS add a condition when to be used. For example:
  • if retry_num > 0 && retry_num < 6 && last_error == ‘tls’
  • then ‘invalid-tls’
  • if retry_num > 5 && last_error == ‘tls’
  • then ‘no-tls’
  • else ‘default’

With this new strategy the email will be delivered on the 5th retry which meanns 62 minutes delay but will be delivered.

Good luck
