Kandydatem jest usługa ZeroSMTP. Tylko 0% wpisów niesie emoji platformy, więc lista nie jest katalogiem programów do zainstalowania i wpis o usłudze ma tu sens.

Check before submitting

• The list actually accepts hosted services. If every entry carries a license and a source link, it is a list of self-hostable software and ZeroSMTP cannot qualify however the entry is worded — close this.
• Self-submission is permitted. If it is forbidden, close this — slipping one in gets the project banned from the list permanently.
• If it is permitted but must be disclosed, the PR body discloses it.
• The entry sits in the right section, in the right alphabetical position.
• The format matches the neighbouring lines exactly — dash style, trailing period, link form.
• Any minimum age, star count or license requirement is met.
• Their linter (awesome-lint, remark) passes locally.
• Sklonowane przez git -c core.autocrlf=false clone - inaczej Windows przepisze konce wierszy calego pliku.
• Po commicie, przed git push: python tools/check-submission.py --repo <klon> --max-lines 3 wychodzi czysto. Jednolinijkowy wpis wyszedl juz raz jako commit na 4417 linii.

Draft entry

- [ZeroSMTP](https://msgwing.com) — Free SMTP relay that still accepts plain username-and-password SMTP AUTH, for printers, scanners, NAS units and legacy apps that cannot do OAuth2. 200 messages/day; sends from a shared @msgwing.com address rather than your own domain.

The 200/day cap and the shared from-address stay in. They are what make the entry survive review — a list maintainer checks, and an entry that hides its limits is rejected once and remembered afterwards.

Close this issue once the PR is open, or if the list turns out not to fit. Closed issues are remembered, so it will not be queued again.
