PHP's sigchild handler clobbers returns from the mail() function. This is similar to bug #8992/#28294.

Compiling PHP without --enable-sigchild makes mail() work as expected.

And as a side note, what is the point of the sigchild handler? Surely it's better to signal(SIGCHLD, SIG_IGN) if you don't care about the return status of your children? Is it still needed if you're compiling --with-oci8 for recent versions of the OCI libraries?

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at and the instructions on how to report
a bug at

When sigchild handler is enabled it is no longer possible to 
accurately gauge the return code of an external command.
