Install AcelleMail on AWS EC2

No strong reason. The guides say MySQL 8 mostly because that's what the AWS RDS default lands on and it's what we test against, not because MariaDB is a problem. Everything the app does goes through Eloquent, so if MariaDB works for the rest of your stack, keep it. Two things worth checking either way: use utf8mb4 for the charset, and give the DB user enough grants to run migrations (it creates and alters tables). If you hit something on MariaDB that works on MySQL 8, tell me the version and the query, I'd rather fix it than have the guide quietly assume one engine.

24.04 is the newest anyone's reported back on. php-imap and php-sqlite3 get called out because they're the two the wizard's requirement check stops on and neither is in the default php meta package.

Good to know the supervisor block pasted clean. One thing worth flagging for anyone else on EC2: if you deployed as `ec2-user` rather than `www-data`, change the `user=` line in that config to match whoever owns the app directory, otherwise the workers start but the queue silently writes files root can't read later. The rest of the walkthrough assumes an Amazon Linux/Ubuntu path split, so if you hit a different supervisor conf.d location than the one listed, tell me which AMI and I'll add it to the article.

Matches what we see. It's worker count that moves that peak, not list size, so re-check it if you ever bump workers.

No headless flag yet. Run the wizard once by hand, bake that box into an AMI, and let Terraform stamp out from it with per-env values in .env.

This bites people who later put a local DNS resolver or a mail-facing daemon on the same box, and the failure looks unrelated because the install itself goes through fine. Worth noting for anyone hitting it that after editing /etc/systemd/resolved.conf you need `systemctl restart systemd-resolved`, and on 22.04 /etc/resolv.conf is a symlink to the stub file, so point it at /run/systemd/resolve/resolv.conf or you lose name resolution on the next boot. I'll add this as a note under the prerequisites section of the EC2 guide.
