Actionmailer sending many emails in same SMTP connection?

Rails
#1

Hi,
I need to implement a mailing list system,
Actionmailer is great, but i haven’t found out a way to send many
(hundreds of) emails without having to reconnect to the SMTP server for
each mail when calling

Mymailer::deliver_my_mail(recipient)

Any tips?
(Possibly without calling directly Net::SMTP, so i can take advantage
of the rhtml rendering of the body)

Thanks,
Best regards,
Marcus.

Hey Marcus -

you might check out msmtp (http://msmtp.sourceforge.net/)

msmtp activates Pipelining by default.

you can read about configuring msmtp with rails here, http://
wiki.rubyonrails.com/rails/pages/HowToSendEmailsWithActionMailer
scroll to the bottom under TLS configuration.

I’m using it now to test through gmail - like a charm.

cheers, Jodi

Thank you, but i’d rather stick to a more traditional environment,
i’d prefer using smtp or activemailer…

Any other suggestions?

Thanks,
Marcus.

Thank you Jodi,
Would it cache up all the emails and bulk them up to the smtp server?

I’m by no means an expert Marcus, but I know it does enable
Pipelining (bulk sends to each recipient) by default.

I generally use it because my smtp server requires TLS (ssl)
authentication - but it seems pretty full-featured.

For more insight into msmtp (including it’s caching capabilities),
you’ll get more value from it’s docs.

good luck Marcus.
