-------------------------------------
[~asolimando], in the mailing list of dev [[email protected], past month
- Apache Mail
Archives|https://lists.apache.org/[email protected]], I didn't
find the way to start or raise a new question.I tried to send an email to
[[email protected]|mailto:[email protected]] directly with my QQ
email(I'm chinese), but it didn't work. Must I become a committer before
raising a question in mailing list?
