Re: And so it begins... -- MIDRANGE-L

Jeff,

You are correct. This would then mean ONLY the iSeries can send mail to the internet, anyone else that tries gets blocked. If they need to send mail, they send it to the iSeries first and it delivers it.

 On you home Comcast account you are also correct.

I have mentioned before that we routinely block port 25 outbound from customer networks from all but the customer's email server exactly for the reason above.


Help me understand this whole issue.

Current setup:

1) I use the i5 ("mail.dilgardfoods.com") as the mail server.

2) I5 ip address is 192.168.0.1.

3) CHGSMTPA is set to MAILROUTER(*NONE) FIREWALL(*NO) ALWRLY(*NEAR *LIST).
(The only thing in the *LIST is the IP address at my house from Comcast.  It
is fairly static, I have to change it maybe twice a year, but then I can
send email from home through the i5.)

4) Have Verizon DSL.

5) All Windows POP clients use "mail.dilgardfoods.com" as outbound mail
server.


Does this mean I:

1) Only allow outbound port 25 thru the Cisco Pix firewall if it came from
from 192.168.0.1.

2) Do a CHGSMTPA MAILROUTER("outgoingmail.whateververizontellsme.net")
FIREWALL(*YES) ALWRLY(*NEAR)

3) Change my outbound mail server at home to whatever Comcast tells me.


You'd think this stuff would become more clear as the months and years go
on, but it sure doesn't feel like it.
