Sending email from outside and SMTP Authentication

Unanswered Question
Aug 20th, 2009

Hello all,

I was told earlier that company users can send emails from outside using either VPN or SMTP authentication, is there a third way to do this? if yes, please mention it...

I also require some information on how to configure SMTP authentication...

your help is highly appreciated...


I have this problem too.

I believe you're reffering to the ESA C-Series appliance, but you've posted in the WSA forum.

I'm moving this posted to the appropriate forum, please let me know if I've misunderstood your post.

yes, you are right, I meant the C-series, thanks for shifting the case to the appropriate forum...
