Rainloop can't send message

Hi Support,

I had successfully installed cyberpanel & created email also, but when I login to rainloop webmail and try to send email it shows "Can't send message" .

I have installed cyberpanel on Centos 7.6 also configured spam assassin.
Postfix is also enabled with sufficient email limits.

I am receiving emails but unable to send it via rainloop webmail.

Thanks

  • Who is your provider, maybe they have blocked your email ports, you can troubleshoot using this guide -> https://cyberpanel.net/docs/troubleshooting-cyberpanel/
  • Hi Team,

    I have checked that with the server provider & they have open mail ports 25, 587 for sending email.

    Below is the email error log I am getting.

    Previously I used cloudflare as DNS but not configured private nameservers & now DNS is also managed by Cyberpanel . Below is the DKIM entry as TXT record in dns setting.

    ---------------------------
    TXT default._domainkey.mydomain.com 3600 v=DKIM1; k=rsa p=MIGfMA0GCSqGSIb3D....
    --------------------------------------------

    Any help is appreciated & if you need login details let me know.

    Best Regards.
  • I am using Scaleway for my server provider.

    Also how I can Setup RDNS and Hostname or do I need to ask the server provider to set RDNS .

    Is it required before the server can send mail from server & hosted web application.

    Thanks.
  • by default ports 25, 587 are blocked by Scaleway, you need to ask top open them
  • i install cyberpanel 1.8 in google cloud. my rainloop webmail not sent and receive any email. please help me.
  • Hi @megaolio

    Sending & receiving email doesn't work with Google Cloud on Cyberpanel as google doesn't allow this functions by default as ports need to be manually configured on GCP.

    Using Cyberpanel with GCP since past 6 months.
