• Hi, Pleskians! We are running a UX testing of our upcoming product intended for server management and monitoring.
    We would like to invite you to have a call with us and have some fun checking our prototype. The agenda is pretty simple - we bring new design and some scenarios that you need to walk through and succeed. We will be watching and taking insights for further development of the design.
    If you would like to participate, please use this link to book a meeting. We will sent the link to the clickable prototype at the meeting.
  • (Plesk for Windows):
    MySQL Connector/ODBC 3.51, 5.1, and 5.3 are no longer shipped with Plesk because they have reached end of life. MariaDB Connector/ODBC 64-bit 3.2.4 is now used instead.
  • The Horde webmail has been deprecated. Its complete removal is scheduled for April 2025. For details and recommended actions, see the Feature and Deprecation Plan.

Hi having issues with send out email to certain doamins.

icloud.com
me.com
yahoo.com

Error message =

connect to mx01.mail.icloud.com[17.57.155.25]:25: Connection timed out

They then just sit in the mail queue as deferred. All the rest of email domains go out.

Any ideas of what we could check?

Thanks
 
If your IP is black listed, you would had gotten a bounce back. Since you're getting a connection timed out this is telling me that whoever is hosting your server has outbound port 25 blocked. You would need to reach out to the hosting provider and ask them to unblock port 25.

Wouldn't this affect all email going out and not just some domains?
 
Depends on different factors but connection time is usually always because the port isn't open as I've mention before if it was black listed you would had gotten a bounce back stating as such.

Thanks I'll get it checked.
