When a new account is created on my wiki, MW 1.9.0, PHP5, MySQL4, this message appears:
--- Login successful Could not send confirmation mail. Check address for invalid characters.
Mailer returned: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/London' for '0.0/no DST' instead ---
There are no invalid characters in the email address. In fact, on one occasion at least, the confirmation email was received. Relevant settings are:
$wgEnableEmail = true; $wgEnableUserEmail = true; $wgEnotifUserTalk = true; # UPO $wgEnotifWatchlist = true; # UPO $wgEmailAuthentication = true;

Anyone seen this before?
