 SendmailOptionMayHurtBuggedMTA=Feature to send mails using method "PHP mail direct" will generate a mail message that might be not correctly parsed by some receiving mail servers. Result is that some mails can't be read by people hosted by those bugged platforms. It's case for some Internet providers (Ex: Orange in France). This is not a problem into Dolibarr nor into PHP but onto receiving mail server. You can however add option MAIN_FIX_FOR_BUGGED_MTA to 1 into setup - other to modify Dolibarr to avoid this. However, you may experience problem with other servers that respect strictly the SMTP standard. The other solution (recommended) is to use the method "SMTP socket library" that has no disadvantages.
