Hi Bruce,
Thanks for the information.

My problem was different. The situation I faced was:
* If I use my company’s email account with Mac Mail app to send a patch, then from other email clients that subscribed to pqsql-hackers mailing list, I can see the attachment in the email. But from postgresql.org’s mailing “Archives”, I can only see the email without attached patch file.
* If I use my Gmail account with Mac Mail app to a send a patch, then postgresql.org’s mailing “Archives” will show the email with the patch file. However, the patch file’s content-type is always “application/octet-stream”. I couldn’t find a way to change that.
* Now I switched to use Thunderbird email app with my Gmail account. With that combination, patches file’s content-type is “plain/text” now in “Archives”.
Regards,
Chao Li (Evan)
