I am trying to reduce the use of rails in 3.2.22 of the application and read that the mailbox is eating memory, for example, a buffet ( http://www.schneems.com/2014/11/07/i-ram-what-i-ram.html ) This page says updating the mailbox to version 2.6.3, but actionmailer 3.2.22 seems incompatible with this version of the mailbox.
I only send emails from several places in the application, and I perfectly move the actionmailer and mail stones to a specific Gemfile group, but this does not work. I would prefer not to upgrade to rails 4, but since then a much bigger task.
What are my options?
