Hi, I'm recently running into a probs with hotmail, from my sending server, every emails sent out to hotmail got bounced back and this is what i found in the log: M43120/xx.xxx.xxx.10:5050/host1.xxxx.info;O1;i270;o84;E4;T1320161358;65.55.37.104;[email protected];550 SC-001 (COL0-MC3-F21) Unfortunately, messages from xx.120.xx.xx weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. any fellow MF member's advice how to unblock it? Thanks in advance!
a little more info about my IPs are new, no senderscore yet atm, the blocks happened in the warming up process, i believe I was increasing limits to fast, its ok with yahoo, aol gmail etc.
No it's not ok with yahoo, aol, gmail to increase limits too fast either. Are you backing off when Hotmail throws up "exceeded the rate limit" or "exceeded the connection limit" appear in the SMTP log (there are other messages too)? Those are warning signs, kind of like telling you you're speeding. If you don't listen, you get a ticket eventually (translation: blocked) You have to really tell us more here before we can diagnose a block, you gave us no info. Also, you referred to MF as WF which is really unforgivable, above. Considering a temporary day ban for that one.
If you are warming up, you shouldn't be coming any where near the limits, for connections or number per session. Hitting the limit defeats the purpose, and exceeding it is insane. Warm up is about proving to the majors that you will respect their resources, and even if you hit their posted limits, they will block you if you have no track record with them. Even 1 block during warm up should not only stop the mailing on that ip for that session, but you should probably rest it for at least 24 hours, if not longer. Really is no point in more than 1 connection, 1 email per session, you're warming up not trying to deliver. Big bandwidth spikes on a new ip screams block me. Also, this is debatable depending on which you are more familiar with, but hotmail is usually more forgiving then the other 3, not less. John - in a word ... nope.
Sorry roundabout, my typo :34: I've checked the logs again and see only that one message for all of my IPs.
Actually i have 61 IPs and the system is VoloMP, on my first mail from those IPs, i set 200/h to specific domain like yahoo, so the same limits setting for aol and hotmail, it was fine for the first sending, took a break for 48 hours then came the 2nd mailing, i increased to 400/h, thats when i started seeing blocked from hotmail.
Thanks SG, I presume 200/h from 61 IPs, so it's about 3-4 emails/h for one IP, since there IPs rotation set in the system, btw whats speed do you recommend?
