Hello All, With the risk of being a lamer, I'm going to ask a question with my first post here. I took an extended vacation from mail, and recently started back up. I mail primarily yahoo. I have been working on warming up some ips, but it has been futile so far. I suspect I need to build a small, more responsive list for successfully warming up. Soooooo... I've decided to go ahead and ramp up volume on "unwarmed" ips in hopes of capturing clickers to build a good warm up list. Then I'll go back to attempting to warm up ips again. My question is... Can you use too many ips from the same class c when mailing yahoo these days?? My concern is getting my whole range TS03'd if I use too many at once, or too soon together. Like I said, it's been a while since I've heavily mailed, but I remember triggering TS03 a couple years ago IF too many ips were getting FBLs in a day... I seem to remember it being 14 or 15 ips... but I don't know the parameters now. Any help will be reciprocated... I'm fairly knowledgeable about mailing, but I've been out of the loop for too long, and need to get back up to speed a bit. Thanks, Postmaster .
