my domain is hosted on a plesk panel control, I had migrated my domain webmail from plesk to zoho.I am facing a bouncing problem when I send mail from another webmail of other domain
As Per How to fix “550 Requested action not taken: mailbox unavailable or not local” in Plesk servers
In Plesk Windows servers, the default mail server is MailEnable. Plesk
account owners in these servers sometimes report the MailEnable error
SMTP server response: 550 Requested action not taken: mailbox
unavailable or not local when trying to send out mails or when
managing their account functions through the Plesk panel.
What does this error mean ?
It means MailEnable found the recipient domain of a mail in the
server, but couldn’t locate the email username. For example, let’s say
MailEnable received a mail to be delivered to
“mail-recipient#domain.com”. It would look for active mail services
for “domain.com”, and then for the inbox of “mail-recipient”. If it is
able to locate “domain.com”, but not “mail-recipient#domain.com”, this
error would be returned. We’ve been able to prevent server incidents
by up to 15% by using our proactive server checks (click here to see
how we improve web hosting support).
Why does this happen?
We have noted the following situations in which this error is reported
by Plesk panel accounts.
For some unknown reason, when the recipient mailbox was disabled by the account owner, or because of a bug in Plesk.
When the email account is hosted elsewhere (like Google Apps), but the domain has mail services enabled in the local server. Bonus tip :
If the customer receives this error (as shown below) while using the
Plesk panel, it means that the administrator email for the domain is
set to an email account which is either disabled in the local server,
or is hosted elsewhere.
Warning: Unable to send notification: mail() failed: mail() [function.mail]: SMTP server response: 550 Requested action not taken:
mailbox unavailable or not local
How to fix this error?
If the email service for the domain is hosted elsewhere, just turn off mail services by going to:
Domains > Mail > Disable Mail
If the MX points to the local server, check if the email account is disabled, and if so, re-enable it.

We are currently migrating away from hosting our own mailserver due to not having an IT professional who is experienced in mailserver security (SPF, DKIM, DMARC, etc.). I have attempted to route the cPanel DNS zone records away from The Server which currently hosts several websites in hopes of fixing the problem of our mailserver being blacklisted for sending spam due to a vulnerability.
I have added Google's TXT records and I can successfully setup G-suite addresses for our email addresses locally. However, G-suite keeps suspending the email accounts since some spam from our old server (or an email bomb?) keeps being somehow forwarded to the
What steps do I need to take to prevent our mail from our local workstations from being routed through the server? It keeps blacklisting the emails and they can't get to the correct address.
I'm using WHM and cPanel.
In the WHM "Edit DNS Zones" Go to each Domain and set "Email Routing" at the bottom of the page to "Remotely". Added MX records, SPF, and DKIM as TXT records.
Finally, you can shutdown the dovecot mail application running in Centos.
sudo service dovecot stop
sudo service dovecot status
I have a blocklist for my internal network that reroutes the user to another IP address should there be a match. This is managed via SimpleDNS and a tool within that program. The rerouting works and it goes to the IP address.
Code on the IP website then logs the hit and reroutes to a fully qualified domain and shows the user a message.
Except I now have an issue inbetween SimpleDNS rerouting to the IP and the friendly page being showen

Trying to set up a domain name under cPanel server... so far so good, the problem comes once I am trying to point this domain to an external Kerio Mail server.
Even though from ssh user root can telnet the Kerio Mail server, when the user/domain tries to sent email using this server, get's smtp connection timed out.
Wondering is there's more than DNS changes that need to be made or something else is needed in cPanel firewall (CSF)
To allow SMTP connection to another server, any thoughts ?
If you are trying to send mail from your server and getting timeout then you need to check your firewall. First I will suggest you please try to disable your server firewall and test your mail again.
I have one domain on my server and a mailbox (with the same domain ending) on a different server. I configured the mail and MX fields of DNS of that server to the proper value. All is working. But as I send an email from the website contact form (configured with SMTP = localhost) sending an email to the email address on the other server, the email will not reach the mail box ..Even no error is generated..Simply the mail server receives nothing. On the other hand from the contact form I can send email to different mailboxes.
How to solve this ?
I solved the issue by setting in the first panel for the SMTP settings in MailEnable, the host values to 200.x.x.x which should redirect all the traffic outside the server.
I have a windows server running an application which sends mail via PHP. Some of the people who should be recieving the emails are complaining they are not getting them. I think they are using Comcast or AOL. What can I do to my SMTP settings and/or DNS to allow these to go through?
Investigate SPF (Sender Protection Framework) to increase the authenticity of your emails.
