Thanks a lot for your tips, but it still doesn't work. :( I'm using
gentoo, that already has qmail way patches. I tried to compile it with
the patch in the contrib dir, and it worked out. But the result is
just the same.
But I guess you're totally right. I've tried more extensively and with
Outlook Express it doesn't give any error (I suppose OE doesn't use
CRAM-MD5).
I'm using vpopmail 5.4.6, and qmail is already patched with smtp auth,
but still nothing. Any thing else you can remember?
