[Rails] Multiple emails from one SMTP connection?

[Gerret Apelt]

Ryan,

if you're not customizing the email on a per-recipient basis,
definitely go for sending you email in a single SMTP session. I
believe the ActionMailer API doesn't let you do that as-is.
ActionMailer uses the TMail library internally though, so you might be
able to intercept the TMail instance generated by ActionMailer, and
then send it to multiple recipients, taking away the SMTP portion of
the work from ActionMailer and doing it yourself.

In pseudo-brief, somewhat like this

Net::SMTP.start(server, port) do |sender|
  recipients.each do |recipient|
    tmail.to = recipient
    sender.sendmail tmail.encoded, tmail.from, [recipient]
  end
end

Exactly where to intercept the Tmail object created by ActionMailer,
you'd have to dig to find out.

cheers
Gerret
