• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service.

  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Issue msmtp only accepts one email sender address

Hello,

I am using External SMTP server.
At first it's not working
So I did review Mail log browser and noticed that plesk is sending email using the following email address
When I've tried changing the email registered at the External SMTP server to [email protected]
Email started to work properly as shown here

host=smtp.mydomain.com tls=on auth=on user=[email protected] from=[email protected] recipients=[email protected] mailsize=14674 smtpstatus=250 smtpmsg='250 OK' exitcode=EX_OK

But all emails being sent by [email protected] all failed as shown here

host=smtp.mydomain.com tls=on auth=on user=[email protected] from=[email protected] recipients=root smtpstatus=550 smtpmsg='550 From address must match authenticated address' errormsg='envelope from address [email protected] not accepted by the server' exitcode=EX_DATAERR

How am I going to address this?
Under the Externam SMTP server, you can only enroll one email address

Plesk Obsidian Web Host Edition
Version 18.0.41
 
MSMTP has no limitation on the number of email addresses. The error messages smtpmsg='550 From address must match authenticated address' errormsg='envelope from address [email protected] not accepted by the server' suggests a limitation raised by the (email) provider you're using.

If your email provider requires that the "From address must match authenticated address" when sending email messages then using msmtp might not be very useful.
