I have a unique problem. I am using ipower pop email. Comcast is our ISP. We have a Sonicwall TZ 170 firewall in place. When the sonicwall is in place with default settings except the lan and wan configured and the smtp server is set to ipower's server, emails that are sent to bellsouth.net, gmail.com and a few others that I know of, will never get to there destination. I have no error messages or bouncebacks. The emails leave the outbox and is never heard from again. I can have the sonicwall in place and use comcast's smtp server and they arrive to those destinations within seconds. I can remove the sonicwall and use the ipower smtp server and everything works as well. With the sonicwall in place and I send an email with ipower's webmail to my bellsouth or gamil account, it never arrives. The outlook configuration is correct.
I have spent a day with Ipower support to no avail. does anyone have any ideas?
