## Tips

#### Alias for addresses
Use aliases for questionable services or one-time needs.

Messages for `user+alias@domain.com` will go to `user@domain.com`. It can be useful for spam origin analysis if a unique alias is used for each online service when registering. 
For example, `bank+user@domain.com`, `cryptoexchenge+user@domain.com`, and so on.

#### Directory Filter
Create directories of filters for different purposes. This will help protect against phishing and clogging your inbox. 
The message for `user-dir@domain.com` will create a `dir` directory in the `user@domain.com` mailbox and all mail will arrive in the `dir` directory.

Examples:
  - `user-w@domain.com` - for registering with web services
  - `user-shops` - for web-stores
  - `user-pay` - payment systems
  - `user-forum` - forum notifications
