Trouble E-mailing Comcast.net

All of a sudden for no apparent reason, I can't send an e-mail to ANYone with a comcast.net address. It immediately gets sent to my spam folder stating....<br><br><em>Host comcast.net doesn't support SMTP mail delivery.<br><br></em>SMTP is standard e-mail protocol ! I checked with my local ISP and they tell me nothing has changed on their end. Anyone else ever experience this ?<br><br><br>Mark.

Scott has Comcast..it blows....<br>

From what I've read online, it does blow .....<br><br>But how do I contact the people I need to that have comcast.net addresses now ???<br><br>I have customers that I need to correspond with and am now apparently cut off !!!<br><br><br>Mark.

Try setting up a yahoo acct. i had to do that because i couldnt get thru to some aol users. hope this helps. louis

Or a gmail.com account. I love my gmail account. Comcast has been good lately, but about a year ago if I replied to an email, sometimes it wouldn't gothrough. No problems with gmail though...<br>

Ok .... That's a work-around - but why did it happen in the first place ?<br><br><br>Mark.

I meant to post this earlier. Rooster is on comcast. I imagine that is why you have not been able to contact him. I had trouble getting thru to him. I remembersomething about Comcast has some providers blocked. I am on yahoo and that was 1 of them. Think he had to go thru his ISP to get is fixed.<br>Hope this info helps some.<br>Mike

I was finally able to get through to a Comcast Security agent today (on the phone). Apparently Comcast is VERY stringent on spammers. If one single e-mail isreported as spam, it's blocked by the Comcast server which won't allow it to contact ANY Comcast recipient.<br><br>What I discovered was that there was indeed a blocked IP coming from my end, but was not my personal IP - rather it was my sub-servers IP, meaning someonewithin my server's RANGE had been sending spam ! That being the case, ANYone within my server's IP range had been blocked from contacting ANY Comcastrecipient !<br><br>The tech guy removed the block and provided me with a link for my provider (I know the local tech guy personally) to install a program which will alert themany time Comcast blocks an IP in their range and give them the ability to trace the offending spammer.<br><br>What a hassle just to get an e-mail through !!!<br><br><br>Mark.

Hey Mark,<br><br>Sorry to hear about your SCUMCASTwoes, but as your model railroad brother,<br>LOSE THEM SUCKERS ASAP, BRO!<img src="http://static.yuku.com//domainskins/bypass/img/smileys/roll.gif" alt="image"><img src="http://static.yuku.com//domainskins/bypass/img/smileys/roll.gif" alt="image"><img src="http://static.yuku.com//domainskins/bypass/img/smileys/roll.gif" alt="image"><br><br>Just kidding, but do lose them as soon as you can!<br><br><br>-Larry<br>

Hey Larry - Good to see you back !<br><br>The problem is not with me per se (I'm NOT on comcast) .... the problem was<br>the fact Comcast was blocking me from reaching anyone that IS on Comcast.<br><br><br>Mark.
