Disabling Sendmail from sending patch info

[thewho?]

Hello,
N4000, 11.0, Sendmail 8.9.3
Is it possible to turn off this feature? I noticed that when sending a mail from my HP server, my latest patch is embedded in the mail info, this can't be safe.
Thanks,
Luis

You can disable the start up in /etc/rc.config.d/mailservs. What do you mean by patches being embedded in the mail ?

Look in /etc/mail/sendmail.cf for a line(s) that looks like this:

HReceived: $?sfrom $s $.$?_($?s$|from $.$_)
$.by $j ($v/$Z)$?r with $r$. id $i$?u
for $u; $|;
$.$b

That's the Recieved: format line.

$j is the host name
$v is the version/patch
$Z is the version number alone

Removing the ($v/$Z) part will accomplish what you're after.

My apologies, I misunderstood your question. Eric's suggestion is good.

Manipulate this line as you see fit:

O SmtpGreetingMessage=$j Sendmail $v/$Z; $b

$j - fully qualified domain name (required)

$v - current version of sendmail

$Z - The version of the configuration file you're using

$b - current date time

Think about making it something like
$j Sendmail $Z; $b

(The version is advisory).
