Hi A client is complaining that some emails are not being delivered but no error message is being sent. I ran a check using MX Toolbox and got the following warnings: SMTP Reverse DNS Mismatch - Reverse DNS does not contain the hostname SMTP Banner Check Reverse - DNS does not match SMTP Banner SMTP TLS Warning - Does not support TLS. SMTP Transaction Time 15.169 seconds - Not good! on Transaction Time Do I need to start playing with the EXIM configuration or are these possibly false alarms?

  Hello, The following document is a good place to start: How to Keep your Email out of the Spam Folder - cPanel Knowledge Base - cPanel Documentation Once you have ensured those guidelines are followed, review /var/log/exim_mainlog to see if there's any additional information about what happened to an affected message if the issue persists. EX:
  exigrep affected-email@domain.tld /var/log/exim_mainlog
  Thank you.
