There are some problems with latest Redmine versions. After upgrade to 2.0.2 (the same problem with 2.0.3), when sending e-mail notifications as PLAIN TEXT, something has changed. Now - "<pre>" "<pre>" tag is replaced with ??<notextile><pre></notextile>?? <pre> <pre> </pre> There are some other issues with incoming e-mails as well, but this is another issue.
