Net::SMTPAuthenticationError

shikha · April 11, 2008, 9:28am

Hey guys,
I want to send an email via ROR and I have put this code at the very end
in the config/environment.rb file-

ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.perform_deliveries = true
ActionMailer::Base.logger = nil
ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.smtp_settings = {
:address => “[my smtp server]”,
:port => 25,
:domain => '[my domain],
:authentication => :plain,
:user_name => ‘[email protected]’,
:password => ‘[my password]’
}

but when i click on send mail button, it shows following error:

Net::SMTPAuthenticationError in MailingController#sendmail

502 unimplemented (#5.5.1)

RAILS_ROOT: C:/work/2phone

This is probably saying that the SMTP server you are trying to send
through doesn’t support plain authentication.

Find out what types of authentication your SMTP server supports, this
will help.

What Authentication type should be there for sending an email?

When I changed the type of :authentication in config/environment.rb file, :plain to :cram_md5 now it showed me this error:

Net::SMTPSyntaxError in MailingController#sendmail

Have you actually tried to RTFM of your mail server, and know how it is
configured?

Usually none.

Most SMTP servers don’t authenticate beyond sender domain, source
address and recipient domain.

So try none and see how you go.
