Mail Merge wizard does not send e-mails

Hi to all.

I’m testing the mail merge wizard to send a Writer sheet to multiple mail addresses, but I always get the same message error:

My settings are correct and the Test Setting works:

Can anyone help me? Thanks.

My o.s. is Mac OSX 10.7.5 and LO version is 4.3.7, but I have try in Windows 7 and in Ubuntu yet.

Ciao, are you sure that your settings are correct? That test could give a “false positive”.
Try with Use secure connection (SSL) check mark. And also configure Server Authentication and port 587.
On my system, it works.

If my answer helped you, vote it with :heavy_check_mark: (here on the left)

Wonderful, it works! You are a magician!
Thank you so much.
