Sorry for messing things up. I forgot to restart stunnel after adding relay = yes to the conf file. It works OK for me now.

If you watch port 53 (tcpdump, tshark, etc.), do you see a request leave the host and come back with the old name? It sounds to me like you're getting a stale value from the cache somewhere...
Can you run stunnel under strace or gdb and see what it does to get the hostname resolved?

Hi, I have named local resolver enabled on the stunnel client (FreeBSD 7.0). I did a test on the client and found there was no problem with the local resolver.
- on the stunnel client: dig hostname.dynaip.org --> points to the
correct IP of the stunnel host 2. restart ppp on stunnel host to get a new IP 3. on the stunnel client: dig hostname.dynaip.org --> points to the updated IP of the stunnel host
I tested ftp service on the stunnel host without going through stunnel, and it worked before and after the IP change.

I added delay = yes to my stunnel client conf file and removed the cron script. The rsync job (873) failed after the IP of the stunnel host had changed. I had to manually restart stunnel to get the job done and put the cron script back again.
delay = yes does not with work with ddns.
That's really strange. The relevant client.c code is:
/* setup address_list */ if(c->opt->option.delayed_lookup) { resolved_list.num=0; if(!name2addrlist(&resolved_list, c->opt->remote_address, DEFAULT_LOOPBACK)){ s_log(LOG_ERR, "No host resolved"); longjmp(c->err, 1); } address_list=&resolved_list; } else /* use pre-resolved addresses */ address_list=&c->opt->remote_addr;Maybe you use some kind of advanced/broken resolver library that caches IP addresses?
