[Mailman-Users] Sendmail startup question

Eric Elder Tue, 11 Jan 2005 13:44:12 -0800

I found a tuning tip setting (for Sendmail and Mailman) in the Mailman FAQ that I'd like to implement, but I want to check where exactly to make the change.

I've include the tip below, but here are my two questions: 1) I've found a startup script on my server at /etc/init.d/sendmail, but I'm not sure where to add these lines (if this is even the right file to add it to?) 2) For the change in the mm_cfg.py, when I define the SMTPPORT = 1313, is the 1313 a fixed value, or is that meant to be the "NNNN" value that I used in the earlier startup script.

Here's the tip from the FAQ "6.3. MTA Performance Tuning Tips for Sendmail." It says:

----------------------------------
In your startup script, add:

/usr/sbin/sendmail -bd -ODeliveryMode=defer \ -ODaemonPortOptions=Name=MSA,Port=NNNN,M=E,Addr=127.0.0.1

Where NNNN is some port number not otherwise used (you can test if something's in use by doing "telnet localhost NNNN" -- if it's refused, there's no daemon listening) This sets up a sendmail process listening to the alternate port, in DEFER mode, but set to talk only to the localhost interface, so it's not accessible by anyoneother than your local machine: no open relay problems. To make mailman access that port, add this to your mm_cfg.py:

 # define alternate SMTP port
 SMTPPORT = 1313
----------------------------------


And here are the current contents of my file  /etc/init.d/sendmail

---------------------------------- #!/bin/bash # # sendmail This shell script takes care of starting and stopping # sendmail. # # chkconfig: 2345 80 30 # description: Sendmail is a Mail Transport Agent, which is the program \ # that moves mail from one machine to another. # processname: sendmail # config: /etc/mail/sendmail.cf # pidfile: /var/run/sendmail.pid
