I can't seem to get any of my email accounts in Thunderbird to work with SMTP settings in Windows 8.1 Pro RTM. What am I missing? TIA! Just shut off the native firewall and was able to send email via Thunderbird. Now I must figure out what firewall setting/rule is blocking the send.
After a reboot, same problem again. Thunderbird is still on the allowed programs list in the firewall settings. Am I the only one with this problem??
Just solved it... DOH! Avast being set to scan outbound emails caused a security problem for all smtp accounts in Thunderbird only - none would work. Simply changed that setting in Avast and all is well. I'm a bit confused as to how I was ever able to send an email when the program briefly worked (before the reboot) but I'll not worry myself with that now. Tried Opera mail and it worked without issue even with Avast set to scan outbound... but Thunderbird is my preference.
Ok, he solved the problem! My point were simple: for to be able to send Mail using SMTP you'll have to open the related port (mainly 25) in Router and for the SMTP Server.
Not necessarily... most NAT routers require nothing for outbound usage. Perhaps you're thinking of a port forward if he had an email server needing to receive SMTP from the outside.
Would be depend on the routers base firmware. I had similar problems a few times and solved with just forwarding the port. Also DHCP should be enabled in Router too.
