See http://archive.ledgersmb.org/ledger-smb-users/msg07493.html for the problem report. Mailing recurring transactions doesn't seem to work correctly.
We just did our scheduled invoices run. This time we set ourselves up
to be BCC'd. Unfortunately, we never received the invoices.
I tcpdump'd the lo interface on port 25, and tailed apache access log,
apache error log, exim log, and syslog. Apache error log showed nothing
interesting, all debug info is related to SSL, the access log showed
that the page loaded when we did the transactions. Exim log shows no
connections, and the tcpdump shows no traffic on port 25. syslog
reports no activity at all.
So what ever the problem is, ihttps://sourceforge.net/p/ledger-smb/bugs/873/#t seems that the recurring transactions
are not attempting to mail out through smtp...

happenstance, I happen to have a very old box temporarily back on my
network from when I first opened my business, it has sql-ledger on it,
and it has a bin/mozilla (and a bin/lynx) within its directory
Fixed in r5928.
