Question
Issue regarding Email Service
I have a basic 512 MB Ubuntu 14.04 64 bit VPS with LEMP stack and wordpress. I have installed postfix server.
I have a contact Form 7 plugin installed. When a form is submitted, it is processed without errors. But the message couldn't be found on Inbox as well as Spam Folder.
When I checked the mail queue for postfix on my server, I can see all the emails there. When I reached for the support then they replied that "A mail server often has problems sending mails if it doe not have enough RAM. You may need to consider upgrading to a 1 GB RAM server to successfully send mail."
The question is:
Is there any alternative solutions for the above problem without upgrading the RAM ?
