Why Nginx Mail Module encoded '%' to %25 in Auth-Pass header?

ph flag

I do the test with the special character password below

~`!@#$%^&*()-_+={}[]|\/:;"'<>,.?

And I realised nginx mail module encoded the % to %25, but the rest of the special character are fine, is it pre encoded from mail client level ?

 *3653 http header: "Auth-Pass: ~`!@#$%25^&*()-_+={}[]|\/:;<>,.?" 
 *3653 http proxy header: "Auth-Pass: ~`!@#$%25^&*()-_+={}[]|\/:;<>,.?"

After a while,

I decided to research this module, just realize it's only supports PLAIN_TEXT at the moment.

I will just enabled PLAIN_TEXT authentication will do the trick.

@WoomMonika in case you only have one Mail Server, you can just proxy instead to intercept the connection

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
