</b><br> A. You spell it "Mailman", with a leading capital "M" and a lowercase
second "m". It is incorrect to spell it "MailMan" (i.e. you should
not use StudlyCaps).
+<p> <b> Q. I'm getting really terrible performance for outgoing messages. It
+ seems that if the MTA has trouble resolving DNS for any recipients,
+ qrunner just gets really slow clearing the queue. Any ideas?
+
+</b><br> A. What's likely happening is that your MTA is doing DNS resolution on
+ recipients for messages delivered locally (i.e. from Mailman to
+ your MTA via SMTPDirect.py). This is a Bad Thing. You need to
+ turn off synchronous DNS resolution for messages originating from
+ the local host.
+<p> In Exim, the value to edit is receiver_verify_hosts. See
+ README.EXIM for details. Other MTAs have (of course) different
+ parameters and defaults that control this. First check the README
+ file for your MTA and then consult your MTA's own documentation.
<p> <b> Q. What if I get "document contains no data" from the web server, or
mail isn't getting delivered, or I see "Premature end of script
headers" or "Mailman CGI error!!!"
