I need a clean Postfix installation configured to handle both outgoing and incoming mail. All account, alias, and domain information m...must live in PostgreSQL, so the build has to include the proper SQL maps and permissions from the start. My goals are straightforward: – Mail flows reliably in both directions. – TLS is enforced for all SMTP traffic. – Users authenticate against the PostgreSQL-backed tables. – Standard anti-spam and DKIM/SPF records are in place so messages land in the inbox, not junk. You are free to choose the Linux distribution you’re most comfortable with, but please document every package, file path, and command so I can replicate the setup later if needed. Once the server passes basic send/receive, DKIM/SPF, and relay-restricti...
I already run a WordPress site where municipalities log in to draft their text alerts. Now I need the back-end engine that will actually move those messages from WordPress through playSMS and out via a Dinstar GSM gateway. The core of the job is the integration with Dinstar and playSMS. You will expose a clean REST API (Python with Flask or FastAPI on Linux) that my WordPress plugin can call, pass the message payload to playSMS, and relay it to the gateway. From the same API I also want delivery reports and status updates pushed back to WordPress, preferably through webhooks so the site can show live progress bars for each campaign. Day-to-day workflow I envision • Municipal clerk logs in on WordPress and writes a message. • Message is queued for my approval, schedul...

I’m working with a handful of Polycom IP 550 and 501 sets that refuse to clear their old provisioning data. A full MAC-address factory reset appears to complete, yet the phones immediately pull their previous config on the next reboot. I have them pointing at a local TFTP server (running on Linux) and have already double-checked permissions, paths, and firewall rules—the server never sees a single packet. I’d like experienced guidance to determine whether I’m overlooking a reset nuance, mis-handling DHCP Option 66, or if these units are simply locked to an earlier deployment. What I need from you: • A live screen-share or detailed walk-through that gets at least one phone truly back to factory state and talking to my TFTP server. • Clear con...
