Hi,
Hoping someone can help me here.

For the past 6 months or so, I had an email set up on my linux/sendmail box out of my house where my cablemodem is to forward messages directly to my account at gmail. from there, the filters and rules were used to redirect to pager/cell phone, or sort accordingly as needed.
This was working fine until recently. Looks like on 2/13/2009, google changed their policy.
Now all the messages from my local sendmail smarthost to my gmail account are bouncing.
Here's the error that comes up:
(I've changed the gmail account name and my specific IP's to prevent spamming)
Anyways...
I am looking for a way to actually do what they recommend from their referenced link in that code snippet above... which is to set my sendmail config up on my local linux smarthost to use the SMTP Server for my (Buffalo, NY) roadrunner ISP's SNMP server so that when google runs a reverse-dns check, it checks out as legit, and allows that mail to go through.
Any ideas on how to do this?
- Do I need to forward everything directly to my time warner username (never used it, have no idea what it is!) and then create a ~/.forward to my destination or something from there?
- Would I be able to update my sendmail config so that I could have all outgoing email from my linux smarthost be forwarded/redirected to the TWCi SMTP servers for distribution to the ultimate destination?
The second bulletpoint is preferred, since that would allow for more future flexibility. The email on my local cablemodem smarthost is strictly outgoing-only, I just want to get it out there to my gmail account. No incoming email other than private stuff from other computers on my local LAN is delivered to the smarthost on my network.
Any help or guidance is much appreciated!
