I’m sorry to use this forum to ask a question not directly about gpg4win, but the question is regarding information found on the gpg4win.org web site. If there is a more appropriate way to get help, please let me know.
What is the correct email address to contact professional support?
Per http://www.gpg4win.org/support.html, I’ve attempted to send an email to gpg4win-professional@intevation.de, and it was bounced back as Undeliverable by aktaia.intevation.org.
The most apparently meaningful part of the error message is:
“Helo command rejected: Host not found”
This is coming from the United States, if there are regional differences to account for.
