Hello,

we send e-mails with a curl command line. Previously we used the version
7.40 and sending the e-mail works fine.
Since we have to switch to a current version, sending does not work anymore.

We always use the same command line and change only the curl version.

Here are the Logs using Curl 7.40 (working)

curl: (56) Failure when receiving data from the peer

Are there new command line parameters that you have to use now? When
looking at the parameters,
I did not notice anybody whom I connect with the error message "curl:
(56) Failure when receiving data from the peer".

Kind Regards

Rainer Eisel
