Hi I just did an install under wamp... not surprisingly mail() failed (not drupal's fault)
but i was surprised that the only message I got was:
warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\wamp\www\first\includes\mail.inc on line 193.
Unable to send e-mail. Please contact the site administrator if the problem persists.
this was buried in a list of about 100 other warnings (i've posted a bug report on those)... given the seriousness of this failure for the install I thought this fail should probably be promoted a bit more to the user
just a suggestion
