Re: [Davmail-users] 2 minute delay when sending mail after network change

The problem happens if I switch to a different wifi network in my home. So I still have the same external IP address, but a different LAN IP address (192.168.x.y). It also happens when I switch from home to work, in which case I of course have a different external IP address. I don't think either situation should affect how I connect to the remote O365 server. I don't use any HTTP proxies, VPNs, etc. Note that the log shows that after the network change, davmail is still able to talk to the server: the EHLO gets a response. It's the authentication step that seems to block. If it would help, I can send more logs, e.g. for a fast connection when the network hasn't changed.
