Question

操作系统：FreeBSD-11.1

名称：amavisd-new-2.11.0_2,1

我们最近开始从邮件日志中报告的amavisd中获取这些错误：

 . . .
 proxy-reject: END-OF-MESSAGE: 451 4.5.0 Error in processing,
 id=29937-07, quar+notif FAILED:
 mail_dispatch: no recognized protocol name: -2
 at /usr/local/sbin/amavisd line 9638.;
 . . .

这些错误中的每一个都是由于处理来自单个域的消息而导致的。但是，并非该域中的所有流量都会产生错误。

该消息中提到的amavisd代码部分如下：

   9619   my $any_deliveries = 0;
   9620   my $per_recip_data = $msginfo->per_recip_data;
   9621   my $num_recips_notdone =
   9622     scalar(grep(!$_->recip_done && (!$filter || &$filter($_)),
   9623                 @$per_recip_data));
   9624   while ($num_recips_notdone > 0) {
   9625     # a delivery method may be a scalar of a form protocol:socket_specs, or
   9626     # a listref of such elements; if a list is provided, it is expected that
   9627     # each entry will be using the same protocol name, otherwise behaviour
   9628     # is unspecified - so just obtain the protocol name from the first entry
   9629     #
   9630     my(%protocols, $any_tempfail);
   9631     for my $r (@$per_recip_data) {
   9632       if (!$dsn_per_recip_capable) {
   9633         my $recip_smtp_response = $r->recip_smtp_response;  # any 4xx code ?
   9634         if (defined($recip_smtp_response) && $recip_smtp_response =~ /^4/) {
   9635           $any_tempfail = $recip_smtp_response . ' (' . $r->recip_addr . ')';
   9636         }
   9637       }
   9638       if (!$r->recip_done && (!$filter || &$filter($r))) {
   9639         my $proto_sockname = $r->delivery_method;
   9640         defined $proto_sockname
   9641           or die "mail_dispatch: undefined delivery_method";
   9642         !ref $proto_sockname || ref $proto_sockname eq 'ARRAY'
   9643           or die "mail_dispatch: not a scalar or array ref: $proto_sockname";
   9644         for (ref $proto_sockname ? @$proto_sockname : $proto_sockname) {
   9645           local($1);
   9646           if (/^([a-z][a-z0-9.+-]*):/si) { $protocols{lc($1)} = 1 }
   9647           else { die "mail_dispatch: no recognized protocol name: $_" }
   9648         }
   9649       }
   9650     }

但是我不知道从何处获得协议名称。由于该错误，有问题的邮件未放置在隔离文件夹中，因此我无法对其进行检查。

这是我们方面的配置错误，还是电子邮件传输格式错误的结果？无论哪种情况，我该怎么办才能解决？

Amavisd错误mail_dispatch：没有识别出的协议名称
