    Is there any way to find out why this install is failing for me? I'm trying to install the MSMTP component in a highly restrictive environment, so I believe the yum utility is unable to access the necessary url or IP being used to download this component. Also, is there a way to install components via command line?

    @Blake, 

    The cause of failing install may be found in log file /var/log/plesk/install/autoinstaller3.log

    To install components via CLI, use the command "plesk installer" and follow the instructions from the appeared menu.

    Looks like these are old steps.

    Don't work right now with Plesk Obsidian 18.0.25. for me.

    If I try to install MSMTP (relay only), Plesk uninstalls Postfix and also Dovecot.

    I try to continue, then I try to install only Dovecot and Plesk uninstalls my MSMTP (relay only) and Installs the Postfix again.

    It's a loop process.

    @Santiago,

    MSMTP cannot be used with local mail server like Postfix. MSMTP is used as external SMTP server for outgoing mail for notifications only, that's the only aim of it in Plesk.

    As it is stated in this article: "If local mail server is installed, it will be removed along with other mail components like Mailman, SpamAssassin, Dovecot."

    See more details here: https://docs.plesk.com/en-US/obsidian/administrator-guide/mail/using-plesk-without-the-mail-server.72346/

    It is not possible to use local mail server in Plesk like Postfix AND external SMTP server.

    If information from the documentation above does not address your request, let us know why you want to use local and external mail servers at once in Plesk.

    Hi Julia,

    Thanks for the information.

    The situation where we need the local mail server and the external SMTP simultaneously is when we want to continue to use the Plesk to manage the domains e-mail accouts/mailboxes and use an external SMTP service for example to send newsletters for the same domain.

    @José Graça,

    In this case we recommend using Plesk mail server only for this purpose. Newsletters scripts can be adjusted to include Plesk SMTP server instead of the external one.
