Can you check the user has correct permission? check if the folder have 775 permission EG ```auto sudo chmod 775 /var/www/ghost ``` & your current user is the owner of the folder for Example ```auto sudo chown $USER:$USER /var/www/ghost ``` ---

Okay seems its not a config issue… but i am suspecting the issue with the nodemailer… may be we should wait for some experts to answer on this. @John@egg ---

The nodemailer version used by Ghost is 0.7.1 [Ghost/package.json at main · TryGhost/Ghost · GitHub](https://github.com/TryGhost/Ghost/blob/master/package.json#L120) Did you change this manually @workman? ---

Okay, well by default the nodemailer version is 0.7.1 🤔 How did you install Ghost? I would try removing your `node_modules` directory and running `yarn` to reinstall the correct versions of dependencies ---

Installing the nodemailer version 0.7.1 worked for me. Thanks for all your time and help @egg @inoryum.
