    Achelous, a sendmail replacement, which queues and uploads emails to a web service. We designed it for IoT devices and containers, which might send emails for administrative purposes. https://github.com/core-process/achelous

        Awesome, thanks for your feedback. Please let me know in case you need further information or in case you want to share some feedback with us. We use Achelous on thousands of IoT devices already. :-)

    Good Day!

    1 to 4 are Mail Transport Agents (MTA)s
    5 & 6 are Mail User Agents (MUA)s and are not MTAs! “Email Clients” are MUAs not MTAs … period!

    The title should read:

    4 Best Mail Transfer Agents (MTA’s) for Linux and a couple of MUAs ;-)

    To get to 6 MTAs one can include:

    5) CourierMail Server courier-mta : the Courier mail transfer agent (MTA) is an integrated mail/groupware
    server based on open commodity protocols, such as ESMTP, IMAP, POP3, LDAP,
    SSL, and HTTP. Courier provides ESMTP, IMAP, POP3, webmail, and mailing list
    services within a single, consistent, framework.

    and even the light weight ->

    6) dma – https://github.com/corecode/dma – DragonFly Mail Agent – dma is a small Mail Transport Agent (MTA), designed for home and office use. It accepts mails from locally installed Mail User Agents (MUA) and delivers the mails either locally or to a remote destination. Remote delivery includes several features like TLS/SSL support and SMTP authentication.

    PS: Having used all 6 MTAs I stick with Exim if possible.
