Our Email configuration in workflow had been set in port 26 and working well for the last 2 years however our ISP has auto blocked the said port. We tried to use the standard port 25 and 587 however still these ports was also blocked after a day of usage. We tried to contact them to solve this issue to release the said ports however this issue is repeatedly encounter in our server.

Right now our email is using the port 465 (SSL) and its working in Outlook account however in WF configuration I cannot use this port and it's giving me a request time out error.

Is there any other way you could recommend on setting the WF email Configuration to help me
in this problem?
