Guest guest Posted September 23, 2001 Report Share Posted September 23, 2001 this is doing the rounds ATM as an explaination of the AOL problem! individual mails goin missing/never appearing would seem to be a localised ISP/account problem rather thna a wider thing as incidents like that tend to happen to individuals occasionally, whereas this AOL thing seems widespread. HTH Angi >> >> >>Q. Why does list mail come out of order or hours/days late or never >appear >>at all? Why do AOL members not get all the list mail or digests? >Why does >>it take hours or days for list mail to get to Hotmail or Yahoo email >boxes? >> >>A. Because AOL, MSN, Yahoo email, Hotmail, Earthlink, et al, are >large email >>providers. They get literally tons of email and they have to watch >their >>servers carefully because they can get overloaded. >> >>So they prioritize. They give private email priority over group or >list >>mail. >> >>Yahoogroups is the largest email list provider (pay or free) and they >send >>out literally tons of mail. Large chunks of that mail go to the >largest >>email providers like AOL, MSN, Yahoo email, Hotmail, Earthlink, etc. >Since >>those large email providers give priority to private email, when >their >>servers are busy, they will refuse connections with Yahoogroups. >> >>In other words, Yahoogroups tries to connect to them but their >incoming mail >>servers say no, try again later. So Yahoogroups holds the mail and >waits, >>tries again later until the email provider (AOL, MSN, Yahoo email, >etc) will >>accept the connection and receive the mail from Yahoogroups. >> >>So that's why things come late and out of order. In addition, AOL >has >>admitted that they trash some email from Yahoogroups when their >servers are >>busy, so some Yahoogroups mail is lost and never delivered to AOL >members. >> >>This also applies to the confirmations sent by Yahoogroups to confirm >your >>email address or your subscription or unsubscription requests as well >as >>notices to listowners and moderators about pending posts or members. >>Sometimes these confirmations and notifications take hours or days to >get to >>you or never show up at all. >> >>If you really want to check things out, you can review the full >headers of >>delayed messages. The Received: lines at the top of the headers are >the >>most recent, the top one will be when your ISP or mail provider >received it >>from Yahoogroups. The Received: lines before that one are transfers >between >>internal Yahoogroups servers. So look at the time on the topmost >Received >>line and compare it to the time on the Received line just below that. >Adjust >>for time differences if necessary and if there's a big gap, it means >>Yahoogroups was trying to contact your ISP or mail provider and >couldn't get >>thru, so they waited and tried again and again until they got thru. >> >>In the case of AOL, it's also possible there's a delay after AOL >received it >>and before they delivered it to the AOLer's mail box as AOL has >admitted >>that they do sometimes accept mail from Yahoogroups and then hold it >>somewhere in their system until their servers are not so busy and >then >>deliver it to the AOL member's mail box. >> >>Sometimes an ISP or mail provider isn't reachable after hours or days >or >>trying to send mail and then Yahoogroups considers it a soft bounce. >> >>Some Yahoogroups list owners that use Yahoo email have reported >seeing a >>message in their bounce history (go to My Preferences and click on >Bounce >>History) that says " Yahoo mail servers unreachable for too long " . >This means >>Yahoogroups tried to send mail to them for a long period and finally >gave >>up. This may happen with any of the large ISPs or mail providers if >they >>experience temporary server problems and have to severely curtail >their >>incoming mail for a period of time until the servers are fixed and >list mail >>like Yahoogroups is always the first thing they restrict. > Quote Link to comment Share on other sites More sharing options...
