Can't authenticate with mail server

[Jerry Seutter]

Hi,

I am having difficulty sending notification emails through a mail server.
Here is the trace output:

I have verified the username, password and hostname.

The server is not using TLS. Why is cruisecontrol issuing STARTTLS?

Here is the relevant section from my site_config.rb:

ActionMailer::Base.smtp_settings = {
:address => "smtp.int.xxx.com",
:port => 25,
:domain => "xxx.com",
:authentication => :plain,
:user_name => "yyyyyyyy",
:password => "xxxxxxxx",
}


The behaviour is the same with cruisecontrolrb 1.2.1 and trunk.

Any ideas?

Awesome. The way I read it, your Microsoft Exchange Server is
configured to not accept AUTH PLAIN. Try to add :authentication =>
:login to ActionMailer::Base.smtp_settings hash. If I read the
ActionMailer and Net::SMTP code correctly, this should make CC.rb use
AUTH LOGIN instead of AUTH PLAIN.

Re STARTTLS. CC.rb (trunk) monkey-patches Net::SMTP to try and open a
TLS connection. If server responds with an error code, CC.rb restarts
the SMTP conversation from scratch (literally, closes the socket,
opens another one, says EHLO again etc).

Reasons:
1. We want to TLS because GMail SMTP server requires it.
2. Some old SMTP servers that don't have TLS drop the connection after
rejecting STARTTLS.
