RTFM,
here is the part you are interested in:
%Mail::Sendmail::mailcfg

This hash contains all configuration options. You normally edit it onc
+e (if ever) in Sendmail.pm and forget about it, but you could also ac
+cess it from your scripts. For readability, I'll assume you have impo
+rted it.

The keys are not case-sensitive: they are all converted to lowercase b
+efore use. Writing $mailcfg{Port} = 2525; is OK: the default $mailcfg
+{port} (25) will be deleted and replaced with your new value of 2525.
.

$mailcfg{retries}

    $mailcfg{retries} = 1;

    How many times should the connection to the same SMTP server be re
+tried in case of a failure.

    Default: 1;
