hmm, could be. I haven't run Imail 4 in a long time. Maybe SMTP AUTH and
various SMTP Security options were added in Imail 5. I run 5.09, here with
hopes for 6.04.

If spam is bothering you, I'd upgrade to 5.09, or take a look at this:

That soluton work for giving you much better spam defenses that any Imail
version and it works with Imail 4. and it's free. vbg
