For SMTP, Gandi support ports 25, 465 (SSL) and 587. If neither 25 nor 587 (with authentication) is working, try 465. In this case, you should specify My server requires authentication on the Servers tab of the account's properties sheet. Click the Settings button, select Log on using and enter the username and password for the account.
On the Advanced tab, change the outgoing (SMTP) port to 465 and select This server requires a secure connection (SSL).
Close down WLMail and wait a few minutes before re-launching and sending a test message. Please post back with any new error message.
I have tried all the outgoing server port options: 25, 465(SSL) and 587. When I first switched to 587 outgoing mail worked for a short time ,and then it went back to not being able to send. I can receive and there is no problem with my ISP. I am pulling my hair out!
