,I have a problem with email : I can receive email , but I cannot send .
The problem is the firewall ( if I turn it off it works ) .
These are my rules :
Code: Select all
root@LianLi:/home/ikar0# ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), deny (outgoing), disabled (routed)
New profiles: skip
