Mac Forum / Applications / Eudora / April 2006

Every now and then, I can't send mail in Eudora. It just happened, and
to troubleshoot it, I tried sending mail from my ISP's webmail, and I
had no trouble at all. When I hit the Eudora "help" button that pops up
when I can't send, it took me to a Eudora forum that talks about some
troubleshooting options, none of which solved the problem. I called my
ISP and they said they blocked my account because I sent "300 emails in
one 5-minute span" (at 7:16 pm), which is against the (anti-spamming)
rules. I knew about that rule, and, although my musician husband
regularly sends notifications of his concerts, he said he sent an email
with only 27 cc addresses at 7:16 pm. I get lots of mails (daily) from
my own email address ("spoofed"), so I asked the technician if spoofing
could be causing the excessive emails. He said it doesn't seem so, since
the 300 came from my own IP address. I said, well, can't hackers spoof
IP addresses? He said not really. He put me on hold and when he came
back he said it's a known problem that Eudora has a glitch whereby it
sometimes sends multiple instances of emails, which probably explains
the 300 emails. While I was on hold I googled "IP spoofing" and got
pages and pages of references to it. I told him about it and he said
it's not really possible to do that. He unblocked my account, and now i
can send mail, but what gives? I've tried Outlook Express, Mail,
Thunderbird, and others, but always come back to Eudora, because I
really like it overall, except for this apparent sending (and sometimes
receiving) problem. It just dawned on me: if my ISP blocked me from
sending, why was I able to send from the webmail account? (I plan to
call them back and ask.)
