Hi,  
I’ve been working with ruby on rails now for around 4 weeks, I am  
having several issues with an apps I’m working on that was not developed  
by myself, the site was made by a company that we no longer in contact  
with. I’m running the site locally and seems to be running fine apart  
from I cant send out the newsletter via the admin section, it doesn’t  
come up with any error and looks like on the log its should be sent out  
fine.  
So I decided to see if I was missing a gem that may be required for this  
to be sent out. I was given a list of required gems by the developer  
and on this list there was a mail factory gem. I can’t seem to install  
this gem locally (on windows) and when the gem is installed onto the  
server (Linux) it makes the CPU usage go from 4% to 80% and the site  
was taken down by the hosting company.  
I’ve been working with this for a round 2 weeks now on this problem and  
have started to become a bit desperate.  
Does anyone know of any reason why the mail factory gem may be causing  
this increase or if there is a similar gem that could be used?  
Cheers Chris

can’t help you with mail factory

we use the ActionMailer for all our mailing.  
i don’t know if this mail factory offers any special functionality, that  
ActionMailer doesn’t cover, but for simple sending around some  
newsletters or any other everyday mailing like forgotten password or  
registrations ActionMailer is good enough
