From and Reply_to in emails

I am trying to change the emails for a website but soemthing a bit odd is going on


Foir the email to the customer I have

$this->email->from('website-contact@aaaa.com', 'ccc');

$this->email->reply_to('bbb.net', 'cccc');


But the from is coming out as bbb.net not website-contact@aaaa.com

The smtp user is
$config['smtp_user'] = 'bbb.net';

Any idea why the from is bbb.net not website-contact@aaaa.com

I can change the reply_to to website-contact@aaaa.com alright but that isn't what they want

I have spent most of yesterday trying all sorts but got nowhere

Thanks

Which version of CodeIgniter are you using?

I did some testing here in CI3 on my local server using sendmail and it looks like sendmail ignores whatever email->to() value you use. It always takes the smtp sender from sendmail.ini.

I thought the man at the Host had alresdy changed the config but he hadn't. Bit of confusion somewhere. I realised on Saturday that it might be that and got it working. Thanks

You can't do this with Microsoft 365, they have disabled SMTP for all tenants. What do you recommend for sending SMTP mails?
