Mutt has this really annoying thing about previous releases. I thought 1.4.x came with smtp support, not true. I found out also that Centos 5.6 doesn't come with the latest releases of mutt. It got really fraustrating fishing for rpms. I couldn't find any reliable repos around with rpms so I opted to compile it.
I wasn't really sure if I could, since I haven't touched C for such a long time. Anyway, with a couple of tries I was able to get pass the configure phase. This is what I did.
