Possible cause for "Eudora got tired of waiting for the server"?

[Gilles]

Hello

Using the exact same e-mail profile that works the rest of the time,
occasionally, some outgoing e-mails aren't being sent and triggers a
timeout:

"Error reading from network
Eudora got tired of waiting for the server. (10100)"

I suspect my ISP blacklists some e-mails or domains (although
blacklisting the whole of yahoo.com seems improbable), hence the
timeout.

Is there a way to investigate, eg. installing a proxy on my Windows
host between Eudora the Interweb?

Thank you.

Based on this document�
www.eudora.com/techsupport/ini.html#Heading12

I closed Eudora, added the following to eudora.ini, restarted Eudora
and tried sending the e-mail again:

[Debug]
LogLevel=1

Unfortunately, Eudora didn't append anything to eudora.log.

Why won't it send an e-mail to jd...@yahoo.com isn't being sent?

Thank you.

Problem solved when using 127 instead: Turns out my ISP's outgoing
SMTP server (wrongly) thinks that the email I'm trying to send to
someone @yahoo.com is SPAM.

Sorry for the confusion.

Thanks Jim, but the problem is solved: Turns out my ISP's SMTP had a
CRLF issue so Eudora wouldn't display the error message (which was
that the server mistakenly thought some of my outgoing e-mails were
SPAM).
