2021-05-05 06:26:15.292 WARN  [liferay/mail-3][MailMessageListener:135] Email [email protected] will be ignored because it is included in mail.send.blacklist
2021-05-05 06:26:15.295 WARN  [liferay/mail-3][MailMessageListener:52] Skipping email because the sender is not specified

Answer 1

After LPS-84320 Liferay denies sending mail when sender is unconfigured in your installation.

Following default emails are consider as not valid unconfigured emails: [email protected], [email protected], [email protected], and [email protected]

In order to avoid that warn traces and mail issues, you will have to configure a correct email in your portal-ext.properties:

admin.email.from.address=...your admin user email...
announcements.email.to.address=...your no-reply email...
