I’ve been trying to track down a formatting problem in my plain text  
emails that I’m sending out. After a couple hours, I think it might be  
due to the version of ActionMailer that’s being used…

The problem is that when sent from my dev machine all’s good, but when  
sent from my production server, I get extra blank lines inserted.

I’m actually still developing using rails 1.2.6 on my dev machine, and  
setting RAILS\_GEM\_VERSION to this version but the deployment  
configuration has rails 2.x and other gems installed alongside the  
older gems. So I ~think~ that’s coming into play.

Any thoughts about whether I’m on the right path in thinking that the  
new ActionMailer is being utilized and whether, in fact, it’s  
formatting output differently?

Also - If anyone knows if it’s possible to set the version of other  
gems ala RAILS\_GEM\_VERSION can you point me to where I can learn how?

Thx
