On my system, sendmail logs are rotated by savelog (syslog), not
logrotate, so none of the above applies.

... or every week, depending on how it is called (from cron.daily or
cron.weekly). Actually, depending on the output of the
"syslogd-listfiles [--weekly]" command.

Actually, cron.weekly.

-c # specifies number of cycles, not necessarily days. So, when making
the proposed changes, please consider the number of weeks for which you
want to keep the logs.

Also be aware that changing the savelog line will also apparently impact
all the other weekly log rotations handled by the syslog/savelog dynamic
duo, like daemon.log, messages, lpr.log, auth.log, ...

It's really a PITA not to have logs handled by logrotate, huh?
