I have been trying to resolve this issue for several days with limited progress.

I can use Ximian Evolution Email client from my RH 9 Linux box and send mail to my AOL account with no problems.

If I send via sendmail as delivered, I get this error back:

<<< 550-The IP address you are using to connect to AOL is a dynamic (residential)
<<< 550-IP address. AOL will not accept future e-mail transactions from your
<<< 550-IP address until your ISP removes your IP from its list of dynamic
<<< 550-(residential) IP addresses. For additional information, please visit
<<< 550-http://postmaster.info.aol.com.
<<< 550 Goodbye
... while talking to mailin-03.mx.aol.com.:

So, I added:

define(`SMART_HOST',`smtp.comcast.net')dnl

to sendmail.mc and did a make -C /etc/mail. The sendmail.cf is now updated. I then did a restart of sendmail.

Now I see the following in maiilog

May 14 22:50:25 localhost sendmail[2902]: h4F5oPNT002902: from=<root@localhost.localdomain>, size=303, class=0, nrcpts=1, msgid=<200305150550.h4F5oFp9002900@localhost.localdomain>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1]

So, it appears to be going to smtp.comcast.net though it still does not arrive. I started looking at SMTP AUTH and how to configure sendmail to act like my mail client which works fine from the same machine to AOL, but then it suggested telnet to smtp.comcast.net and doing ehlo and checking for AUTH which it does not show.

So, question is:

How does my mail client send mail to smtp.comcast.net and works fine but I cannot get sendmail to send mail in the same manner. What am I missing?

Thanks

AOL doesn't take mail originating from residental private machines because of spam problems. Basically AOL blacklisted your subnet (and most other private subnets) for mail rather than face the potential for spammers using it.

See SForsgren. Unfortunately, I believe EvilRhino is right. Like I said in your other thread, it's because AOL is flat out blocking many residential IP addresses, which is what Comcast (and several other ISP's like Verizon) use. Sorry, but I really don't know any other way around the problem. I have the same issue!

OK. Help me understand this:

I CAN send mail from my Linux box to my AOL account using my mail client which sends through smtp.comcast.net. Works fine.

So, why can I not get sendmail configured to do the same thing? What is the difference between how the mail client talks to smtp.comcast.net and the sendmail program talks to smtp.comcast.net.

One works. The other does not. So, I have proven that there is a way to send mail from my machine via Comcast to AOL. I just don't know how to get sendmail to do the same.

Thanks

That's weird. What is the e-mail address you are sending from on Comcast directly? I guess I am wondering what your setup is. You are sending e-mail directly from your linux box (what e-mail address?) to your AOL account, and that works. Yet, you're saying that on the same machine, you can't send to your AOL account through sendmail using a different server?? Where is your sendmail server? What do you need sendmail at all for if Ximian Evolution is doing what you want? This doesn't make any sense to me...

Hi Chris. Thanks for the comments. When I login to Evolution, I login as SForsgren@comcast.net. Sends through smtp.comcast.net from the mail client and all is well. Have to login of course. Sendmail has SMART_HOST of smtp.comcast.net but not sure how or where to setup the From or the userid and password that I normally use for the mail client. Sendmail is running on the same box with my Evolution client. The reason that I need sendmail to work is I am doing some PHP web development and it will email to users. If they put in an AOL account, it will never get to them. The mail client discussion was just to illustrate that I can get it to go from the mail client through smtp.comcast.net to AOL fine, but I need to be able to send email to AOL users from the web application as well and I believe that PHP is using SMTP for the mail feature. So, wouldn't that be going through sendmail? Thanks again!
