## Versioning
The version numbers follow the [Semantic Versioning 2.0.0 ](http://semver.org/ ) scheme.
2016-09-10 15:10:52 +03:00
## Yahoo.com
Aliases work different on Yahoo than on Gmail. On Gmail part after plus is skipped.
2016-09-13 19:20:51 +03:00
For example message sent to `janedoe+alias@gmail.com` will be redirected to `janedoe@gmail.com` .
2016-09-10 15:10:52 +03:00
Yahoo uses the following pattern[*](https://help.yahoo.com/kb/SLN16026.html):
*baseName*-*keyword*@yahoo.com
* *baseName* - value defined by the user, different than email login;
* *keyword* - one from a list of keywords defined by the user.
2016-09-10 15:45:30 +03:00
Therefore we do not know what is the real email, so in this case result will be `baseName@yahoo.com` ,
2020-02-17 12:00:02 +03:00
which actually does not exist.
## Yandex.ru
In official [documentation ](https://yandex.com/support/mail/web/preferences/about-sender/additional-addresses.html ) you can find some use-cases about aliases usage.
## Mail.ru
2020-02-17 17:00:23 +03:00
There's no official documentation about aliases here, but you can create them with these ways:
2020-02-17 12:00:02 +03:00
* `janedoe+alias@mail.ru` will be redirected to `janedoe@mail.ru`
2020-02-17 17:00:23 +03:00
* `janeDoe@MAIL.RU` will be redirected to `janedoe@mail.ru`
Also, it's possible to create aliases in the settings of Mail.ru, for example, like these ones:
* `janeDoe@list.ru` will be redirected to `janedoe@mail.ru`
* `janeDoe@inbox.ru` will be redirected to `janedoe@mail.ru`
* `janeDoe@bk.ru` will be redirected to `janedoe@mail.ru`
