I've been removing the old system during the upgrade script since 4.9, coincidentally. I haven't had a problem yet while upgrading two production servers and my two laptops, from release to release. After selecting the OS sets during the upgrade, but before hitting ENTER, type ! at the “Set name(s)?� prompt to enter a shell. Then run: `cd /mnt && rm -rf bin sbin usr/!(local) && exit`. Then just hit enter and continue running the upgrade script. WARNING: this will wipe out your system, so if the upgrade fails for some reason, you are TOTALLY SCREWED! I periodically (every few releases) clean out /usr/local. First, get a list of manually installed packages using `pkg_info -m`. Then uninstall everything. It is interesting to see what gets left behind. If any garbage is left over, remove it. Then reinstall from your generated list. I don't do this very often anymore as `pkg_delete -a` seems to clean up quite well. As insurance, I take level 0 dumps just before upgrading or cleaning /usr/local. Also, one of my laptops is a spare that has all the same software installed as the production servers and my main laptop. So this laptop is a test run if you will. If there are quirks, my main laptop is my second chance to make sure I know what the hell I'm doing before finally upgrading my two production systems. Also, just a public announcement, test your restore-from-backup process once in awhile. I've always thought about sharing this process, but always thought it is probably not the best advice. Clint, pkg_add sysclean This will restore your system as close to a new install as possible. What you are doing is quite dangerous. But the very next step in the upgrade blows away the system by overwriting it anyway. Right? What could happen? What if following the normal procedure of untaring the OS sets on top of the existing system fails midway? Then you have an inconsistent system too. I'd rather start with a clean slate and build on top of that than chip away at an existing, running system, which others have recommended via the sysclean package (I haven't looked at the code so I don't know what it does, but I wouldn't trust it until I inspected the code). I have all my OS sets and packages stored on a local server along with my level 0 dumps, which I've never needed by the way. If the worst happens, I just PXE boot the ramdisk image and do a quick restore of the system to where it was just before the upgrade. I've always liked the clean install process, and this modified process gets me close without actually doing a clean install. I've done this for 11 releases now with 4 systems without any problems. Just thought I'd share, but with the warnings I provided earlier. This behavior of mine may stem from my days as a hard-real-time embedded systems engineer where we had to get rid of every single byte that did not matter. I used to count the assembly instructions and add up all the clock cycles for each hardware interrupt routine to make sure we would never stall/slow the system. I just like minimal I guess.

What about to have paused remote delivery on cloud proxy (and deliver on request initiated from home server) and paused remote delivery on home mail server as well and unpause the queue when you do tcp port forwardning to cloud host as well. Or just run VPN between cloud host and home host. If either of them won't be available your mail will stay in queue. j.

socat could do the job… provided you've got something to daemonise it.
(e.g. supervisord)
Another one to look at would be xinetd (isn't in ports, so that'll have
to be hand compiled/installed) which amongst other things, can proxy a
service. Something like:
> service https_port_forward
> {
> flags = IPv6 # Use AF_INET6 as the protocol family

> redirect = yourhost.dynamicdns.service 65025 # Your OpenSMTPD server port
> only_from = ::/0 0.0.0.0/0 # Allow world + dog
> port = 25 # Listen on port 25
> }
The 'yourhost.dynamicdns.service' could also be an entry in /etc/hosts
too, since it's only the VPS that needs to know about it.
I used something similar to work-around OpenVPN being unable to listen
to a dual-stack TCP socket for port-sharing with HTTPS.
https://stuartl.longlandclan.id.au/blog/2016/11/06/dual-stack-openvpn-port-sharing-with-https/
nginx also has a SMTP proxy feature:
https://www.nginx.com/resources/admin-guide/mail-proxy/
Or you can go the whole hog and have your host VPN in to the VPS and
have the VPS do firewall-level port forwarding, which side-steps what
the ISP might do nicely.
Hadn't heard of relayd though, I might have a look at it.

Running OpenSMTPD at home behind a cloud proxy
Hey all, I'd like to pull my emails out of the cloud and run them on a local server (pcengines APU2 looks good). My ISP blocks tcp ports below 1024 and sending email from a residential (dynamic) IP might mark my email as spam. Right now I'm thinking of renting a cheap VPS and using it as a proxy for my home server which would use a dynamic DNS. I don't really want a copy of the email on the VPS so I was planning to use relayd or socat to route incoming traffic to my local OpenSMTPD server. But I don't really see a way to proxy outgoing connections from smtpd... Any ideas? Thanks, Joris
