I think I found out the problem of SMTP in my server. I patched qmail with
toaster 0.5, there is not any problem. I can send out message with or
without SSL enable. But after I patched chkuser.patch, I can send out
message only with SSL enable. So I think it is the problem in
Chkuser.patch.
Not so. I use 0.5 + chkuser on countless servers, and cannot reproduce your problem. Besides, if this were so, you'd lose a majority of incoming mail. Still sounds like a client problem to me.
Note: I turned of SSL for this message.
