In any case, I'd check with your MTA software (sendmail, lsmtp, postfix, whatever), and see if its logs say that Listserv is delivering duplicate destinations or not - it's quite possible that Listserv isn't the real problem here. I'm going to guess that your MAXBSMTP is set to 1000, and that SORT_RECIPIENTS is set to something that doesn't force duplicates to be sorted into the same bundle of 1000. So if it's a small job, all the duplicates are handed to the destination at the same time, and the destination sees a duplicate RCPT TO: and ignores it - but a large job the dup is in a separate SMTP transaction and not easily tagged as a dup. > Sometimes I need to send a message to duplicate email addresses. other times > it should be to only distinct email addresses. *boggle* Under what circumstances is it actually *useful* to send it more than once to the exact same destination address?
