Sounds like your ISP is blowing smoke. IE doesn't send mail nor does it
receive any although it does tie into an e-mail program you specify. Eudora
is the best and safest e-mail program around. When you hear of a virus
program and a patch for some security hole, is the program mentioned Eudora
or Outlook?
All programs that send or receive e-mail use the ISPs own mailer daemons
(SMTP or POP3). The e-mail clients only format messages according to
existing RFC standards, such as RFC0822 STANDARD FOR THE FORMAT OF ARPA
INTERNET TEXT MESSAGES (http://www.faqs.org/rfcs/rfc822.html). The sending
and delivery is handled by RFC1939 Post Office Protocol - Version 3
(http://www.faqs.org/rfcs/rfc1939.html) or
RFC0821 Simple Mail Transfer Protocol (http://www.faqs.org/rfcs/rfc821.html)
From the headers on your e-mail
Received: from LocalHost (dailin47.dailin.macam98.ac.il
[192.114.209.47]) by mail.mofet.macam98.ac.il (8.9.3+Sun/8.9.1) with
SMTP id EAA22841 for <[EMAIL PROTECTED]>; Wed, 23 May 2001

it appears your ISP is using Sendmail version 8.9.3 (for a Sun machine)
probably running Solaris 8. Sendmail is the largest UNIX Mail Transport
Agent. The Release notes and known bugs don't state any problems with
Eudora, likewise the differences between Berkeley 8.X vs. 8.X+Sun, which
ships with Solaris 7 and later don't have any noticeable configuration issues
(http://www.sendmail.org/vendor/sun/differences.html)
Way back in 1999 there was some mention of people who got stuck in limbo
using Eudora. However, the problem could affect any users of the POP
protocol; Eudora, Pegasus, Netscape mail, NuPOP, Popmail, mailit!
might all suffer the same fate.
Could be POP configuration issues. Are they using Sun's ipop3d POP3
server or Eudora's Qpopper? Qpopper is the most widely used POP3 server for
Unix/Linux (http://www.eudora.com/qpopper/)
Some Sun users prefer the ipop3d server over qpopper but that is just a
preference issue.
