@srenon I try to compare the two databases Email password field in core_config_data.
I found a version of the password is encrypted, the latest version is not encrypted.

[srenon]

Try re-saving ... and check the password again.

I just reenter my password on php 5.x, then check the password and it is encrypted.

So this must be a php7 or the changes you make issue.

Also what do you mean by previous and latest version?

[shuaiZend]

I try re-saving password again. but still can't send email.
last version is 1.1, previous version is 1.0.
version 1.1 in databases is not encrypted email password.

[srenon]

Undo the changes you made for php7 and try saving again

[shuaiZend]

I rollback data.php in php7.
and run cil cache:flush
and resaving password again.
still not encrypted.

[srenon]

Try doing bin/magento setup:upgrade instead. I just test on the dev branch without any issue

[shuaiZend]

still not encrypted.
