Hello I\'m a Korean developer I do not good at English I beg your understanding Question 1If I modify apache email source, should I make modified source public? For example, in githubThe apache email library refers to javaxmail library (CDDL + GPL 20), so I think it should publish the source of the modified apache email Is this correct? please reply Thank you
