  1 | # Contributor Covenant Code of Conduct
  2 | 
  3 | ## Our Pledge
  4 | 
  5 | We as members, contributors, and leaders pledge to make participation in our
  6 | community a harassment-free experience for everyone, regardless of age, body
  7 | size, visible or invisible disability, ethnicity, sex characteristics, gender
  8 | identity and expression, level of experience, education, socio-economic status,
  9 | nationality, personal appearance, race, religion, or sexual identity
 10 | and orientation.
 11 | 
 12 | We pledge to act and interact in ways that contribute to an open, welcoming,
 13 | diverse, inclusive, and healthy community.
 14 | 
 15 | ## Our Standards
 16 | 
 17 | Examples of behavior that contributes to a positive environment for our
 18 | community include:
 19 | 
 20 | * Demonstrating empathy and kindness toward other people
 21 | * Being respectful of differing opinions, viewpoints, and experiences
 22 | * Giving and gracefully accepting constructive feedback
 23 | * Accepting responsibility and apologizing to those affected by our mistakes,
 24 |   and learning from the experience
 25 | * Focusing on what is best not just for us as individuals, but for the
 26 |   overall community
 27 | 
 28 | Examples of unacceptable behavior include:
 29 | 
 30 | * The use of sexualized language or imagery, and sexual attention or
 31 |   advances of any kind
 32 | * Trolling, insulting or derogatory comments, and personal or political attacks
 33 | * Public or private harassment
 34 | * Publishing others' private information, such as a physical or email
 35 |   address, without their explicit permission
 36 | * Other conduct which could reasonably be considered inappropriate in a
 37 |   professional setting
 38 | 
 39 | ## Enforcement Responsibilities
 40 | 
 41 | Community leaders are responsible for clarifying and enforcing our standards of
 42 | acceptable behavior and will take appropriate and fair corrective action in
 43 | response to any behavior that they deem inappropriate, threatening, offensive,
 44 | or harmful.
 45 | 
 46 | Community leaders have the right and responsibility to remove, edit, or reject
 47 | comments, commits, code, wiki edits, issues, and other contributions that are
 48 | not aligned to this Code of Conduct, and will communicate reasons for moderation
 49 | decisions when appropriate.
 50 | 
 51 | ## Scope
 52 | 
 53 | This Code of Conduct applies within all community spaces, and also applies when
 54 | an individual is officially representing the community in public spaces.
 55 | Examples of representing our community include using an official e-mail address,
 56 | posting via an official social media account, or acting as an appointed
 57 | representative at an online or offline event.
 58 | 
 59 | ## Enforcement
 60 | 
 61 | Instances of abusive, harassing, or otherwise unacceptable behavior may be
 62 | reported to the community leaders responsible for enforcement at
 63 | shubh622005@gmail.com.
 64 | All complaints will be reviewed and investigated promptly and fairly.
 65 | 
 66 | All community leaders are obligated to respect the privacy and security of the
 67 | reporter of any incident.
 68 | 
 69 | ## Enforcement Guidelines
 70 | 
 71 | Community leaders will follow these Community Impact Guidelines in determining
 72 | the consequences for any action they deem in violation of this Code of Conduct:
 73 | 
 74 | ### 1. Correction
 75 | 
 76 | **Community Impact**: Use of inappropriate language or other behavior deemed
 77 | unprofessional or unwelcome in the community.
 78 | 
 79 | **Consequence**: A private, written warning from community leaders, providing
 80 | clarity around the nature of the violation and an explanation of why the
 81 | behavior was inappropriate. A public apology may be requested.
 82 | 
 83 | ### 2. Warning
 84 | 
 85 | **Community Impact**: A violation through a single incident or series
 86 | of actions.
 87 | 
 88 | **Consequence**: A warning with consequences for continued behavior. No
 89 | interaction with the people involved, including unsolicited interaction with
 90 | those enforcing the Code of Conduct, for a specified period of time. This
 91 | includes avoiding interactions in community spaces as well as external channels
 92 | like social media. Violating these terms may lead to a temporary or
 93 | permanent ban.
 94 | 
 95 | ### 3. Temporary Ban
 96 | 
 97 | **Community Impact**: A serious violation of community standards, including
 98 | sustained inappropriate behavior.
 99 | 
100 | **Consequence**: A temporary ban from any sort of interaction or public
101 | communication with the community for a specified period of time. No public or
102 | private interaction with the people involved, including unsolicited interaction
103 | with those enforcing the Code of Conduct, is allowed during this period.
104 | Violating these terms may lead to a permanent ban.
105 | 
106 | ### 4. Permanent Ban
107 | 
108 | **Community Impact**: Demonstrating a pattern of violation of community
109 | standards, including sustained inappropriate behavior,  harassment of an
110 | individual, or aggression toward or disparagement of classes of individuals.
111 | 
112 | **Consequence**: A permanent ban from any sort of public interaction within
113 | the community.

39 | 
40 | ## 💻 Installation
41 | 
42 | ### Using as a Library
43 | 
44 | Add Flux Mail to your Rust project:
45 | 
46 | ```bash
47 | cargo add flux-mail
48 | ```
49 |

51 | 
52 | ## ⚠️ Limitations
53 | 
54 | - Attachments are not displayed in the hosted version.
55 | - Email will be removed after 7 days from the database.

--------------------------------------------------------------------------------
 1 | This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
 2 | 
 3 | ## Getting Started
 4 | 
 5 | First, run the development server:
 6 | 
 7 | ```bash
 8 | npm run dev
 9 | # or
10 | yarn dev
11 | # or
12 | pnpm dev
13 | # or
14 | bun dev
15 | ```
16 | 
17 | Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
18 | 
19 | You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
20 | 
21 | This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
22 | 
23 | ## Learn More
24 | 
25 | To learn more about Next.js, take a look at the following resources:
26 | 
27 | - [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
28 | - [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
29 | 
30 | You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
31 | 
32 | ## Deploy on Vercel
33 | 
34 | The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
35 | 
36 | Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
