mod_md: v2.3.2 MDMessageCmd :: Mailsend is broken

Have a messagecmd.bat file to send a mail, in contains:

@ECHO OFF
D:\servers\apache\bin\mailsend -q -f steffen@xxxxxx.com -smtp 127.0.0.1 -user xxxx@xxxxx.com -pass xxxxx  -name "SteffenAL" -t xxxxx@xxxx -sub "Lets Encrypt MDMessageCmd" -M "Something happened with a managed domain:" -M "%~1" -M "%~2"  -M "%~3" -M "%~4"  -M "."

with v2.2.7 and v2.3.1 all is working fine

With 2.3.2 no mail is sent and in the log:

[md:info] [pid 16032:tid 2268] cmd(D:/servers/apache/bin/MDMessageCmd.bat) stderr: Could not connect to 127.0.0.1:25\r\n
