I am trying to get a device on my network to send pop email notifications to my outlook account but can't seem to get it to work. I have enabled the outlook account to accept pop and enabled the client to send them. I'm not sure if I'm missing something or what, any help would be greatly appreciated.


Here is my config:

debug = info
output = stunnel.log
[outlook-pop3]
client = yes
accept = 110
connect = pop-mail.outlook.com:995

[outlook-imap]
client = yes
accept = 143
connect = imap-mail.outlook.com:993

[outlook-smtp]
protocol = smtp
client = yes
accept = 25
connect = smtp-mail.outlook.com:587


Here is the log as well:
