About some smptd(8) log message

Hello Gilles,

When some spammer try to reach an invalid address in my server the log
says "Invalid recipient":

[...] smtp failed-command command="RCPT TO: <NO@NO>" result="550 Invalid recipient: <NO@NO>"

But, when the domain name part is valid (one of those included in my
"vdomains" and "valiases" tables), it appears a "Mailing list expansion
problem" message:

[...] smtp failed-command command="RCPT TO:<NO@YES>" result="524 5.2.4 Mailing list expansion problem: <NO@YES>"


In case what I assumed above is correct. :-) Is the "Mailing list..."
message expected in this case?


Walter
