What reasons were given for the bounces? The way MailMan works it could easily be that low traffic on your list kept some inactive addresses subbed to your list and a check of the archives shows posts coming through the gateway on Feb, 26, 27, and 28 and then two more on Mar. 5 and 6. There was only one post in Jan. -- so it is possible that the addresses went bad between the Jan. message and the 5 days of posts that came later. That would be enough for MailMan to unsub the addresses for bounces all at the same time. Joan In a message dated 3/6/2012 5:43:21 A.M.

So very surprised to find 12 message bounces and subscribers unsubbed in my mail this morning ? Were only 27 subscribers . Are now 24 as 3 more addresses unsubscribed in this evening mail Cant see any link in any of the email addresses .............. Was one @aol.com and another @btinternet.com Have had no emails from anyone asking why they were unsubscribed ? Haven't had anything like this happen for ages Should I just delete all or what ?
