I did a website for a client in the Netherland, with his site hosted by vimexx.nl

The form works perfectly well, but vimexx give the following message as reason why notifications are not sent to my client:
"This message has been rejected because it has an overlength date field which can be used to subvert Microsoft mail programs"

Anybody has any ideas what to do?

(I have tried form on my local servers with no problem)

This might sound obvious but have you tried a short date format?

Hi Wayan

The form has no date fields.

The responses I get from Google search date to 2003 and 2006 and does not give any answers.

It could be something to do with the PHP version your email server thing is using, what version of PHP are they using? and when did they update it?, if that message started around the same time, that's too much of a co-incidence (check the error log on your server for the emails,)

Problem solved thanks.

It was the PHP version.

The server was set to v8.0 I changed it to v7.4 and now it works fine.

Thanks Wayan

There's hope that CC will soon update the Form Builder for these php V8 conflicts. Until then you can stay on 7.4 until they do. Some hosts aren't allowing users to downgrade.

Hi Eric

Yes, I have that problem with some hosts that no longer support v7.4

I do hope CC will have the update ready soon.
