Description: ------------ The composer.json file claims the package is BSD-2-clause, however: All files actually have the BSD-3-clause license in their header, except for Mail/sendmail.php which is "version 2.02 of the PHP license". So what exactly is the proper license for this code?

More digging...looks like bug #15620 was never fixed fully?

The license of Mail/sendmail.php prevents this file from being packaged in Debian, due to its strict copyright policy. It would be appreciated if it could be updated to the BSD-3 license, just like the other files. Thanks!

According to #15620 and https://github.com/pear/Mail/commit/ead639efc855e17508d27f10af05d2dd0aed752a all files should use 2-Clause BSD license. We've had permission from all authors, but the license change was applied only on package.xml file. We have to update the license statement in all files accordingly.

Aleksander, would it help if a patch was provided?

Yes, let's update Mail/sendmail.php so the license is consistent.

chagenbu, can you have a look at the PR?

Reading through the history on this, I'm not convinced that the originally intended license change was to BSD-2. Since nearly all the files were updated with BSD-3 text, I'm thinking that 2010-02-08 commit by doconner/clockwerx used the wrong URL, along with an ambiguous "BSD Style" name. As such, I'm thinking the proper fix here is: add BSD-3 text to sendmail.php; update license name and link in any files that don't explicitly say "BSD-3" and its opensource.org link. Opinions?

Yes, that seems to be the correct thing to do.

Fixed in upcoming v1.4.0.
