Remove automatically added email body text on email attachment

[mlevy823]

It would be nice to have an option of removing the automatically generated text that gets put into the email body when attaching a document to an email.

Your message is ready to be sent with the following file or link attachments:

Example.pdf

Note: To protect against computer viruses, e-mail programs may prevent sending or receiving certain types of file attachments. Check your e-mail security settings to determine how attachments are handled.

Sumatra isn't doing that. It's your e-mail program and it's impossible for Sumatra to change that.

Ah I see. It didn't happen with adobe acrobat so I just assumed it was sumatra. It seems that Windows is doing it (I am using Outlook). Apparently it is the "Send to" feature built into windows explorer using sendmail.dll.

I can confirm that this also happens in Thunderbird when attaching a pdf to an email via SumatraPDF, not just Outlook. I am using the prerelease with the CmdSendByEmail as a toolbar shortcut.
