MTA_IGNORE_ERRORS

Send the message as long as at least one To: address was okay and at least one input source was okay. By default, the message will not be sent if any of the To: addresses are illegal (such as, bad syntax, restricted, unknown host), or if any of the input sources proved to be bad (such as, could not open an input file). The item_address and item_length fields are ignored for this item code.
