... and I'm pretty sure you also need UDP 53 as well.
Be sure those other ports you mentioned are TCP and not UDP. Whenever
mentioning ports it's essential to also mention the protocol, since there is
no such thing as "port 80," only "TCP port 80," "UDP port 80," etc. etc.
You can and should test the outgoing DNS and SMTP connection yourself from
the SMTP server by using NSLOOKUP, type=mx, yahoo.com and then doing TELNET
yahoos.mail.server.com 25 and using the commands like these to see what is
happening:
helo mydomain.com
mail from:sender@mydomain.com
rcpt to:recipient@yahoo.com
subject:optional
data
start typing your message here
continue typing message
. [e.g. type a period and hit enter to stop the message]
exit
Also, if your router was blocking anything, it should show up in the logs.
You should consider setting up a free syslog client such as
www.kiwisyslog.com to be able to capture and inspect the logs.
