I am sending out test mails to my 3 emails at hotmail, gmail and yahoo. They all go through except to my yahoo. I do not have any filters set on my yahoo. Any way to tweek bulkmailer to get them to go through to yahoo?

I have tried with the very last v6.4 and my Hotmail, Yahoo and Gmail accounts. I got messages sent to all three. Is it true that Yahoo is much slower. I mean, the message appears almost instantaneously at Gmail. It takes half a minute to get it on my Hotmail box but it takes more than 5 minutes to get it at Yahoo.

Note that we re-uploaded v6.4 last friday with several optimizations that are part of next v6.5. Try to download that new version and try again.
