The setup is fairly simple, it's Windows Server 2019, with hMailServer as a mailserver, and IIS hosting RoundCube, and of course, PHP.
Sending mails work fine, but when the attachment gets over like 30-50 MB, they get sent, but it isn't displayed in the body.
Here's what I've done to increase the size
- Increased Size in SMTP of hMail
- Increased MaxContentLength in Request Filtering of IIS
- Increased max_post/max_upload (Not the actual variables) in php.ini
- Increased size in RoundCube config
I have disabled all the plugins in RoundCube since the mails wouldn't even be sent with the plugins
Is there a certain plugin to resolve this or does RoundCube have limitations in attachments other than the IIS' limit?
Being able to send about 500MB max would be the best for me.
