Hello,

I'm using using: - dovecot 2.3.3 (dcead646b) - postfix 3.3.1 - dovecot "quota = maildir:User quota"

I'm facing the error:

"quota-status: Error: quota-status: Client sent invalid recipient address: Invalid character in path"

This occurred with this e-mail address: "John Smith"@keit.eu

That is weird. I just tested that the SMTP path parser in Dovecot correctly handles the address as you present it above. But I wonder what Postfix actually sends. Unfortunately, the current error message in quota-status is rather unhelpful in that regard. You could apply the following patch (against master, but v2.3 should be no problem) to get a better error message: diff --git a/src/plugins/quota/quota-status.c b/src/plugins/quota/quota-status.c index c88586d55..fdfd0fc4c 100644 --- a/src/plugins/quota/quota-status.c +++ b/src/plugins/quota/quota-status.c @@ -1,6 +1,7 @@  /* Copyright (c) 2013-2018 Dovecot authors, see the included COPYING file */  #include "lib.h" +#include "str-sanitize.h"  #include "ostream.h"  #include "connection.h"  #include "restrict-access.h" @@ -169,8 +170,8 @@ static int client_input_line(struct connection *conn, const char *line)                         SMTP_ADDRESS_PARSE_FLAG_BRACKETS_OPTIONAL,                         &client->recipient, &error) < 0) {                         i_error("quota-status: " -                               "Client sent invalid recipient address: %s", -                               error); +                               "Client sent invalid recipient address `%s': " +                               "%s", str_sanitize(line + 10, 256), error);                         return 0;                 }         } else if (str_begins(line, "size=")) {

Well I know it is not a conventional address but it is normally perfectly authorized.

Yes, Dovecot v2.3 pays special attention to parse these correctly.

When I disable quota check, I can received correctly the incoming e-mail.

So is there a mean to enable quota check with this kind of e-mail address ?

Please try the patch.. then I can tell you more. Regards, Stephan.
