Hi  
I’m new here, and pretty much new on the rails.

I’m trying to set up my application to send emails (needed for salted  
hash login)  
but i keep getting errors.

i’m sure port 25 is not blocked since i’m able to  
send mails  
through PHP scripts.

my smtp settings in config/enviroment.rb are:

# Include your app’s configuration here:

ActionMailer::Base.smtp\_settings = {  
:address =\> “smtp.012.net.il”,  
:port =\> 25,  
:domain =\> “localhost”,  
:user\_name =\> “USERNAME”,  
:password =\> “PASS”,  
:authentication =\> :login  
}

and i also tried with:  
:authentication =\> :plain

and:  
without :domain  
with :domain =\> “[mydomain.com](http://mydomain.com)”,  
with :domain =\> “www.012.net.il”,  
without username and password

nothing worked…

i don’t want to use local smtp (like sendmail) because i’m on a  
dynamic IP  
and other service providers (like walla\gmail) often block mails from  
Dyn IP

any help would be most appreciated

Thanks,  
Gonen

Use “:authentication =\> nil” if your ISP does not require authentication  
for  
SMTP traffic.
