After trying to send an email per smtp, the server (strato) reported: Failed to transport message. Unexpected server response to EHLO command. The server responded: "missing argument in EHLO command" Reproducible: Always Steps to Reproduce: 1. compose email, sent over strato account 2. 3. Actual Results: server responds: Failed to transport message. Unexpected server response to EHLO command. The server responded: "missing argument in EHLO command" Expected Results: sending the mail thunderbird does not have any issues, until recently kmail didnt have any either. I tried different versions of security (none / tls / ssl), didnt help. strangely when I select in the smtp settings dialogue "server requires authentication" each time I revisit the tab it is unchecked, while for my other (working) accounts this remains checked. I deleted the smtp account and entered new settings anew without being successful in sending the mail, the error persists. Also the "server requires authentication" box gets unchecked again. I ll be happy to investigate when instructed
