<![CDATA[Cannot send mail via smtp]]>I wanted to configure Freescout to use a different smtp server as the default Cloudron one, since the outgoing relay enforces a direct relation between auth credentials and used email addresses (as Cloudron does by default).

Unfortunately when testing a custom smtp server Freescout says the sending failed and looking at the Cloudron logging shows the reason for the failure:

sh: 1: /usr/sbin/sendmail: not found

Could sendmail be included for a future app update?

This is what we do in our freescout below. Note we configured this manually:

I am not quite sure what I made differently before, but while I am 100% I got the sendmail error with the smtp option selected, after redoing it is working now for me as well.

Case closed.

individual mailbox Connection Settings

Yes, these are the ones I am talking about. The support mailbox in question is not using the same domain as the cloudron system and therefore i wanted to configuration both IMAP and SMTP for it. But sending then fails because the Sendmail binary is missing (or at least not at the location freescout expects).

There are two settings:

  • Manage -> Settings -> Mail Settings -> System Emails. This is auto-configured to use Cloudron mail server. Is this the one you are referring to? This has sendmail in the dropdown. The default mail address here is like support.app@domain.com . To change this, you change it in the Email section - https://docs.cloudron.io/apps/#mail-from-address

  • The other is individual mailbox Connection Settings . These are not configured by the package at all.
