GitHub user ShaneCurcuru opened an issue:
Reply via client breaks when message too large
When the message being replied too is too large (working theory; could
possibly be odd characters but doesn't seem so), the Reply via your own mail
client silently fails.
Sample message that fails:
Mac/Chrome/Version 53.0.2785.143 (64-bit) with Thunderbird as default mail
client (which works for short messages).
Chrome developer tools shows the GET mailto:... link was clicked, but
(cancelled). It seems to have the right headers and start of the email body
It's likely various client OS/browsers/mail clients have slightly different
max URL lengths. Possible enhancements are either clipping the mailto: at some
default max length, or somehow otherwise abbreviating or shortening some
reply-level in the body somehow (but that would be arbitrary).
If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastruct...@apache.org or file a JIRA ticket
