I've recently had to put two computers into one and aggregated all of my thunderbird email accounts on the new system. There are 5 of them total. On one of them all of my templated emails look correct when I view them in a list. But when I double click on them to send them to a new customer I have two reply-to email addresses showing up. One is for the correct company strongpoles.com and one for another company boundbynothing.net which can't be associated with the strongpoles company. All of the set up in the account settings looks fine and I've never seen this problem before so I don't even know where else to look. I don't want to delete accounts and start over because everything else is correct and showing up in the right order on my screen.
