PSIPostmaster Posted July 10, 2008 Share Posted July 10, 2008 Well, it seems a google search turned up a bunch of Ironport complaints here so I guess I'll add one more. We had a spam issue over the weekend due to compromised accounts. A fair chunk of spam got out before we could respond and understandably, we got on a few blacklists. A pain for us but hey, that's the way the world works these days. We got the accounts locked down, cleared the spam from our outgoing queues and set about getting ourselves off the blacklists. By about midday Monday, we were looking in good shape. Except we were still getting blocked by a few (fairly major to us) sites. Some had error messages that were worth sweet FA but some were referring to SenderBase. Our reputation showed as poor. Fair enough I guess. We're clean now so we'll wait for it to clear. Well, all through until EOD Tuesday, I keep an eye on things. Accounts still locked down, no spam, still a poor reputation. At one point in the day, our reputation had shown as neutral. Check the logs in case of another outbreak that pushed us back into poor? Nope, nothing. Odd. So I write a scri_pt to check the ironport page periodically and let me know if it changes. Well, at 01:30 and 05:40 Wednesday our reputation twitched back into neutral but stayed that way for less than 5 minutes. No external email was sent (or attempted) in that time. I.e. no way for Ironport devices to examine outgoing emails, determine them as non-spam and increase our reputation (or lower if appropriate) just an apparently random spasm By midday, our execs are getting understandably upset at being unable to send email to these other businesses. Some config files get tweaked and ALL email is now being routed via another IP. No email AT ALL is going via the original IP. This is at midday. At 3:30, the SenderBase status changes from poor to neutral then within five minutes is back to poor. Apparently based on 0 information People, it seems as if there is something seriously wrong with however SenderBase is handling restoring the reputation for mail servers it has lowered the reputation for. This is especially bad in light of the fact there is no way to request an increase in reputation from their website or by email (or indeed any other way). If you are thinking of using this service or know someone who is, I'd suggest seriously thinking again. I'll be emailing the affected companies (some of whom we do big spending with) to inform them that their anti-spam software is affecting their ability to do business. Edit: Our alternate IP has been online for less than 5 hours and already its reputation has gone from neutral to good. Link to comment Share on other sites More sharing options...
