Sendmail issue...?

[uprightdog]

I am using PHP mail on Skywalker:

$email="[some email]";
$headers = "From: donotreply@mydomain.com\r\n";
mail($email,"Test", "Test", $headers)[ 

This works fine, unless [some email] is one of my email accounts on Nova. In which case, no email ever arrives.

Support are telling me this is a development issue. I really don't see how, as the same script runs fine on Nova (using an appropriate sender email). Also, I do not receive cron reports from Skywalker, when the email address they are destined for is my Nova account - any other email address works fine, again.

Does anyone have any ideas?

Its possible the email is rejected if the MTA has enabled "verify sender". For example, your cron job emails which could originate from root@something is not verified and thus the email is rejected.

Just an idea..

Do you get any bounces? You could check the exim logs and see the real reason why the emails are rejected.
