Cannot change SMTP server seetings from 3CX to my own custom on Standard Perpetual license.

[mark.s.lowe]

I cannot use a custom SMTP server on my 3CX v15.5.15502.6 Standard Perpectual license. Its stuck on (greyed out) 3CX SMTP server.

I tried refreshing the license and still same issue.

Is the maintenance current?

This is normal with standard.license, you can only use 3cx smtp servers

To use your own smtp servers you need pro or enterprise license

As mentioned standard licences can only use the 3CX SMTP server and 3CX FQDNs. You can see all differences in the version comparison table. https://www.3cx.com/ordering/pricing/
