I am sorry to post over a broadly discussed topic, but I have been reading all the available information and I am still unable to solve the problem.
I am unable to setup a standard and default outgoing email account, to send order confirmations to customers.
I am running ERPNext self-hosted on Wmware with the Production image I got from the website
The problem is the following: I go into email accounts and try to set-up an account firstname.lastname@example.org. I just select “outgoing” mail and default options.
I fill all the required information (using TLS) and I get the message “Invalid server or port”
The settings are correct as they are currently in use with other mail clients.
Maybe a firewall in the virtual machine is blocking some port?
What should I check? And how?
