Password reset self service needs a SMTP relay
Last modified: 2015-10-23 14:33:30 CEST
+++ This bug was initially created as a clone of Bug #37890 +++ When a token should be sent via email to the external address of a user, a SMTP server that is registered in the domain is searched () and contacted. Then happens: --- test@example.com': (554, '5.7.1 : Relay access denied') --- Because relaying a mail for a SMTP client on an external IP without authentication is forbidden - correct. Problem: we cannot authenticate, because the password is unknown. Solutions: * allow all UCS servers to relay without auth: half-open relay - bad! * use localhost: would work, no auth needed, but the server would have to have a relay path configured. This is well documented. Can we expect this from customers? May include the next point. * create a user on the mail server for relaying: raises user-count (license)?
We decided to expect the administrator to make sure the server the backend runs on can send mails away (r64800).
