This is a mail injector based on tokio and Stalwart Labs mail libraries.

For IMAP it's using async_imap.

It is intended to bench your mail servers and your mail server settings.

How does it work?

mailtempest 0.1.0
Mail injector to generate SMTP/IMAP load to a mail platform

USAGE:
    mailtempest [FLAGS] [OPTIONS] <smtp-host> [imap-host]

FLAGS:
    -f, --fixed-pace    there is no random delay between messages. The delay is always pace_seconds
    -h, --help          Prints help information
        --prepare       utility prepare command. It will use the CSV file to replace all the email addresses in the
                        files located in mail directory and rewrite them with .mt extension
    -V, --version       Prints version information

OPTIONS:
        --mail-dir <mail-dir>            directory where the mails are going to be read [default: ./mails]
        --pace-seconds <pace-seconds>    average pace of injection in second for pace maker (float) [default: 1.0]
        --users-csv <users-csv>          CSV file where users login/password can be loaded [default: ./users.csv]
        --workers <workers>              number of workers [default: 1]

ARGS:
    <smtp-host>    host of the SMTP server
    <imap-host>    host of the IMAP server. If not provided, only SMTP load will be injected

If you want logs you can use the env variable RUST_LOG:

RUST_LOG=info mailtempest smtp.host imap.host

For SMTP inbound mail

It reads mail samples from a directory and randomly send them to the configured SMTP url.

It is multithreaded and will send mails concurrently with workers threads (=number of mail users for now).

It sends them with an average of worker_pace seconds. It can be set to 0 to continuously send mails.

For IMAP reading

IMAP clients are run if the imap host is provided.

Clients are logging in at launch. Then the INBOX is selected.

The loop is using IMAP IDLE. Each time an email is received it is fetched.
