Our e-mail system can handle attachments up to a size of 20MB and does not accept executable files (such as files ending in .exe, bat, ps, or cmd), even if they are sent in a zipped (.zip, .tar, .tgz, .taz, .z, .gz) format. Any message of this type sent to us will be bounced back you. Adding an underscore to the file attachment (e.g. file.zip_) will help.
If you want to send us a larger file you can use an upload facility
If requested, we are happy to sign a non-disclosure agreement (NDA), also known as a confidentiality agreement (CA).
In general we will get back to you within 8 business hours. However, it has occurred that e-mails have not reached us for unknown reasons. In case you do not receive a reply within 16 business hours then please see our contact page
for alternative ways of contacting us.
