 * I received this from a user:
 * > I use your WP SMTP plugin, I like it very much, but I’ve a returning issue 
   > with that.
   >  I set up everything, SMTP works fine, test emails deliver, and 
   > then real emails delivered too from the website via the plugin.
   > But, few days later the plugin has authentication issue. And I know about that
   > only, if I send a test mail.
   >  Then I type again the password, and everything
   > works fine again, for few days. What cause this authentication issue??
   > May I suggest a new feature? It would be great, if the plugin could do some
   > self test with the SMTP sender on daily basis, for authentication.
   >  And if

 * I am able to reproduce this by putting it an invalid port number (like a word),
   clicking Save, then putting in a valid port number and click Save again. Password
   is corrupt.
 * I will fix this in the next build.

 * Oh my God, I finally found it. This has been bugging me for months. The Activation
   process was re-encoding the password _sometimes_ during a plugin update.
 * The sometimes being: _If you saved new settings between plugin updates._
 * Fixed again in 1.6.21
