Redmine

Further?

1. Using only one exclamation mark by sentence => Multiple exclamation marks are sign of mental illness
2. Buying me a new crystal ball, or giving use some more information, like what's your version of redmine, your database backend, your ruby and rails versions, what you tried to achieve, what are your way to send email, in which part of the application your meet this error, so on...

As you see, there's plenty of things you can do for yourself.

Redmine version : redmine-0.7.0_RC1
Database back end : mysql5.0
Ruby on Rails :2.0.2
serve : Webrick

target : Email is sent when issue is added or updated.

error occurs when testing the email [error is : An error occurred while sending mail (execution expired) ].

guide please !!!!!!!!!!!

Please REALLY consider point 1.

Have you check your config/environment.rb mail settings? This kind of hang occur when there's a mistake in this configuration. The best to be sure is to disable mail notification: just toggle l.62 to

config.action_mailer.perform_deliveries = false

Once again (by pity), please consider point 1. >_<

I changed to config.action_mailer.perform_deliveries = false
and restarted the server , the result was email was sent successfully !!!
and again changed to config.action_mailer.perform_deliveries = true, the result was (An error occurred while sending mail (execution expired))

i have doubt in configuration

config.action_mailer.smtp_settings = {
         :address => "smtp.mail.com",
         :port =>465,
         :domain => "gmail.com",
         :authentication => :login,
         :user_name => "xxxx@gmail.com",
         :password => "xxxxxxxxx",
 }

config.action_mailer.perform_deliveries = true

we have used the gmail as SMTP server , the protocol SMTP will support ?
if we need to change the protocol(smtps) in ruby how ?

Note : we have used the gmail as SMTP server and protocol is smtps in our application (mail sending is working ).

GMail accept SMTP connection via TLS only. ActionMailer is not TLS capable by default, but there's plenty of doc about changing it. Just follow instructions here, it worked with some redmine users:

There's a new way, simplest, but that I havn't tested yet:

ruby script/plugin install http://svn.douglasfshearer.com/rails/plugins/action_mailer_optional_tls

then configure your mailer in config/environment.rb

config.action_mailer.raise_delivery_errors = true
config.action_mailer.default_charset = "utf-8" 
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
        :address => "smtp.domain.tld",
        :port => 25,
        :user_name =>'login',
        :password =>'pass',
        :authentication => :login,
        :domain => "domain.tld",
        :tls => true
}
config.action_mailer.perform_deliveries = true

Think that if you mentionned you tried to configure gmail SMTP, you'll get this very answer four days ago...

thanks for your guide !!!!!!!!!!!!!!1
it's working !!!!

Please, again, consider point 1 >_<
