• 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.

SMTP Blocked Between ISP's

Hello to all!

I have come across this issue and wanted to know if anyone else has this issue or how to get around it.....

I setup a website and email accounts for a customer. let's say it is www.xyz.com - it is hosted on an ISP called Cogeco

If I add the info@xyz.com in Outlook, and am accessing the internet through the ISP - Cogeco, everything works fine.

If I go to the customers site, with the same laptop, that I know works when it is in the ISP - Cogeco, and they have ISP - Bell Canada, they cannot send email.

They tell me that port 25 for smtp is blocked between the two ISP's

Has anyone else heard of this or if they have, found a way around it without using their SMTP settings?

Brian
