How to send emails with multiple, dynamic smtp using Actionmailer/Ruby on Rails

Question

I saw this post but mine is slightly different:

http://stackoverflow.com/questions/1559879/rails-actionmailer-with-multiple-smtp-servers

I am allowing the users to send mail using their own SMTP credentials so it actually does come from them.

But they will be sent from the Rails app, so that means for each user I need to send their emails using their own SMTP server.

How can I do that?

Answer 1

Just set the ActionMailer::Base configuration values before each send action.

smtp_config = user.smtp_configuration

ActionMailer::Base.username = smtp_config.username
ActionMailer::Base.password = smtp_config.password
ActionMailer::Base.server = ..
ActionMailer::Base.port = ..
ActionMailer::Base.authentication = ..
