Additional IMAP accounts fail to send with SMTP originator not accepted error

  • Hi! I have a few email addresses on different domains that Cloudron handles email for. I have tried to add domain2 and domain3 to my domain1 SOGO account so I can see all my emails in one place like I can with Rainloop.

    Unfortunately, while the initial IMAP setup works and I can read email, anytime I send from domain2 or domain3 it fails with the following error.

    cannot send message: (smtp) originator not accepted 

    My IMAP configuration matches what is shown for domain1 which was filled in by Cloudron when I login, namely the following.

    Server name: my.domain
    Port: 993
    Encryption: SSL
    User name: account@domain2
    Password: {password for account}

    Any ideas what I might be doing wrong or what to try and investigate next?

    @adrw I think this setup doesn't work with SOGo because SOGo does not have a mechanism to have a different SMTP info for each mailbox/account. I am not sure why it's this way but this is how the app is (unlike other email apps). From what I can tell, it's designed to be used with a single account or multiple accounts on the same domain but not different accounts from different domains.

    @nebulon can confirm if this is the case.

    That is correct, SOGo works only with one STMP per account. Also not sure why that restriction ist there and design choice was made.

  • thanks @girish @nebulon for clarifying, definitely a bit of a downer but I hope SOGO opens it up that configuration in a future release!
