E-mail setup will not complete

I am trying to complete e-mail setup, but my provider requires Port 465, but setup will only allow Ports 25, and 587.

I have searched through the forum(s), looked through latest versions (I have 20.9.57), but find no mention of additional flexibility in Port selection. Granted, it is a French-based mail provider, but still…

Please help. Thanks!

Manager does not support Port 465 because it is not officially recognized by governing bodies, despite the fact that many legacy systems still use it. See Email transactions and reports | Manager. You will need to find a different ISP. Or generate PDFs and attach them to an ordinary email rather than emailing from within the program.

Thanks. That’s what I am already doing…
