lando-mail-smtp

Trigger

• "configura el mail en lando", "conecta mailhog", "los emails no llegan en local"
• "el correo no funciona en lando", "quiero ver los emails en local"
• "prueba el envío de correo" / "verifica que llega el email"
• Proactively, right after a lando-setup full install, if the project has any transactional email path (module notifications, order confirmation, password reset, contact form) — ask the user if they want mail wired up now.

Why this is needed

Lando's mail: type: mailhog service alone does not make PrestaShop's Mail::send() deliver anywhere. PrestaShop defaults to PS_MAIL_METHOD=1 (native PHP mail()), which mailhog never intercepts — emails just vanish silently, no error, nothing in the logs. Mailhog only catches mail sent over SMTP, so PrestaShop must be explicitly switched to SMTP mode and pointed at the mailhog service.

Prerequisite — mailhog service in .lando.yml

If not already present (the lando-setup skill's template doesn't add this by default — add it separately), add to services:

services:
  mail:
    type: mailhog
    hogfrom:
      - appserver

Run lando rebuild -y (or lando start if the project isn't running yet) after adding it.

Step 1 — Get the mailhog service's internal hostname

cd ~/developer/{workspace}/{project-name}
lando info

Look for the mail service block:

{ service: 'mail',
  urls: [ 'http://localhost:{PORT}' ],
  type: 'mailhog',
  internal_connection: { host: 'mail', port: '1025' },
  hostnames: [ 'mail.{lando-name}.internal' ],
  ... }

Two hostnames resolve to the mailhog container from inside appserver:

• mail (short alias)
• mail.{lando-name}.internal (project-scoped)

Always use the project-scoped one (mail.{lando-name}.internal), not the bare mail alias. Lando's shared proxy network exposes the mail/appserver short aliases to every running Lando project on the machine — with several projects up at once, the short alias can resolve to a different project's mailhog/appserver container (the exact collision this skill's sibling lando-setup already warns about for fastcgi_pass appserver:9000 in nginx). The .internal form is scoped to this project only and can't collide.

urls gives the mailhog web UI port (e.g. http://localhost:32799) — that's where you'll read captured emails, separate from the SMTP port (always 1025 internally).

Step 2 — Configure PrestaShop's SMTP settings

Via the BO (recommended — matches what a teammate would click through)

1. Log in to the BO.
2. Parámetros Avanzados > Correo electrónico (Advanced Parameters > Email).
3. Set:
   • Servidor SMTP: mail.{lando-name}.internal (from Step 1)
   • Puerto SMTP: 1025
   • Cifrado: Ninguno / off — mailhog doesn't speak TLS
   • Usuario/contraseña: leave empty, mailhog needs none
4. Toggle Usar SMTP / activate SMTP mode.
5. Save.

Via direct DB update (faster for scripted/agent setup, same effect)

lando ssh -s database -c "mysql -uroot {recipe} -e \"
  UPDATE ps_configuration SET value='2' WHERE name='PS_MAIL_METHOD';
  UPDATE ps_configuration SET value='mail.{lando-name}.internal' WHERE name='PS_MAIL_SERVER';
  UPDATE ps_configuration SET value='1025' WHERE name='PS_MAIL_SMTP_PORT';
  UPDATE ps_configuration SET value='off' WHERE name='PS_MAIL_SMTP_ENCRYPTION';
\""

Replace ps_ with the project's actual table prefix and {recipe} with the .lando.yml recipe name (also the default DB name/user/password — see lando-setup). PS_MAIL_METHOD: 1 = native PHP mail() (default, broken for mailhog), 2 = SMTP (what we want).

No lando restart/cache-clear needed for either method — Configuration::get() reads live.

Step 3 — Verify end-to-end

Trigger any email-sending action in the storefront or BO (password reset, a module's notification button, an order confirmation, the passwordless login code flow some PS9 projects use, ...), then check mailhog:

curl -s "http://localhost:{mailhog-port}/api/v2/messages?limit=1" | python3 -c "
import json,sys
d=json.load(sys.stdin)
m=d['items'][0]
print('To:', m['Content']['Headers'].get('To'))
print('Subject:', m['Content']['Headers'].get('Subject'))
"

Or just open http://localhost:{mailhog-port} in a browser — mailhog's own UI lists every captured message with full HTML/text preview.

{mailhog-port} changes across lando restarts in some Lando versions — don't hardcode it in scripts; re-run lando info (or grep its mail block) each time before checking, or read the URL fresh via the browser tab if one's already open.

Gotchas

• Confirm SMTP actually applied — if emails still don't arrive after Step 2, re-check PS_MAIL_METHOD really is 2. Some BO email settings screens silently fail to save if a required field (e.g. "De" sender email) is invalid; the DB update path skips that risk entirely.
• ps_shop_email / PS_SHOP_EMAIL must be a syntactically valid address for PrestaShop to attempt sending at all, even over SMTP — an empty or malformed sender address can cause Mail::send() to return false before ever touching SMTP.
• A module that ignores Mail::send()'s return value never surfaces SMTP failures — if verification (Step 3) shows nothing arriving, temporarily wrap the module's send call to var_dump()/log the boolean return, rather than assuming the module code itself is broken.
• This is a per-project, per-environment setting — ps_configuration lives in the DB, so a fresh DB import from server (lando-setup's DB refresh mode) will overwrite PS_MAIL_METHOD back to whatever the server uses (almost always 1, native mail(), since production servers don't run mailhog). Re-run Step 2 after every DB refresh.
