AR_Mailer Problem

Hi all,

I am using ar_mailer for sending newsletter. I got mails queued in
emails table. However when running ar_sendmail to begin sending the
mails, an exception is thrown:

Unhandled exception wrong number of arguments (7 for 6)
(ArgumentError):
        /usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/
ar_sendmail.rb:408:in `start'
        /usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/

        /usr/bin/ar_sendmail:19:in `load'
        /usr/bin/ar_sendmail:19

I am using ar_mailer version 1.3.1.

I know the solution is this below:

The solution is: make them match either by providing the all required
arguments or delete those unavailable arguments (for you) in the
ar_sendmail function.

How exactly do I fix this error. I am new to RoR. Can someone give
me the steps to modify the environment file please.

Thank you,

Sean McGilvray

which ruby version are you using? I think I had a similar problem
using ruby 1.8.7 and solving it by downgrading to 1.8.6...
