Bouncing Limits at Yahoogroups?
Q: If it only takes one hard bounce to set your address to Bouncing, how many soft bounces does it take and over what time frame?
A: The last time that Yahoogroups techs explained the bouncing limits (somewhere in 2001), it was like this:
1. At least one soft bounce on each of three consecutive days that Yahoogroups tried to send mail.
So Yahoogroups tries to send one email on Monday, it bounces, there's no mail to be sent on Tuesday, Yahoogroups tries to send one email on Wednesday, it bounces, there's no mail to be sent on Thursday or Friday, Yahoogroups tries to send one email on Saturday, it bounces and the member is put on bouncing status after three emails over three consecutive days that Yahoogroups tried to email them. And it could be stretched out even more, if a member was only one list and it only posted one announcement per month, if the member bounced those announcements three months in a row, they'd go into bouncing status.
But if Yahoogroups tries to send mail on Monday and Tuesday and it bounces both days, but then mail gets delivered on Wednesday, the bounce limit is reset and it starts all over again.
2. At least 250 soft bounces in one day. Regardless of how much mail is delivered (not bounced) in one day, if there are 250 soft bounces in that day, the member is put on bouncing status.
3. At least 250 soft bounces in one week. So if mail bounced on Monday, but then mail was delivered on Tuesday, bounced on Wednesday, delivered on Thursday, bounced on Friday, it would pass the first limit (three consecutive days) but if the total bounces for the week were 250 or more, then the member would be placed on bouncing status, regardless of the mail that got thru on two days that week.
And these bounced mail counts are by email address, not by group, so it's the total bounces on all mail to that member from any group.
