Hello Jürgen,

Thanks for the report, but the problem seems to be elsewhere, so the fix
consequently does not fit. It may fix your particular configuration, but
break with other configurations or command-line options.

report_build() is meant to "collect" log fragments at first, without
printing them immediately, and then there might be some size ticker
printed as the message is downloaded and forwarded, and ultimately,
there should be some other message (logged/printed with
report_complete()) that completes the log line and causes it to be printed.

I'll have a look - can you get me your configuration without passwords?
And the command line, too? Feel free to also mask the user/server names
in that case, but be sure to let all information about the destination
(mta, SMTP, LMTP, ... whatever) intact except possibly a nondefault
server name.

Thanks again.

Regards,
Matthias
