Subject: Re: [IMail Forum] SMTP AUTH
Problem
Like
everyone else, I've recently changed our SMTP security settings to Relay for
Addresses. All of our internal clients work fine, however our remote users
cannot send mail. They are using Outlook Express and have the following
settings for SMTP Auth: My server requires authentication is checked under
Outgoing Mail Servers. Under settings for that option, Use same settings as
my incoming mail server is checked. Here is any example of the error message
in the log file:
connect 209.224.182.168 port 14552
07:27
16:22 SMTPD(0006020E) [209.224.182.168] helo
07:27 16:22 SMTPD(0006020E)
[209.224.182.168] mail from test@test.com
07:27 16:23
SMTPD(0006020E) [209.224.182.168] rcpt to janed@whatever.com
07:27 16:23
SMTPD(0006020E) [209.224.182.168] ERR mail.test.com invalid user to janed@whatever.com
Kim,
Here's what the Imail log of a successful SMTP AUTH session
looks like, with my Eudora SMTP AUTHing with CRAM-MD5 and "relaying" through
Imail to some weird company somewhere:
07:22 09:03 SMTPD(C7120086)
[212.73.210.73] connect 212.73.210.79 port 4279
07:22 09:03 SMTPD(C7120086)
[212.73.210.79] EHLO sv.Go2France.com
(
at this point,
the SMPT
client will send the SMTP AUTH command
Imail returns with a CRAM-DM5
key
the SMTP client uses the key to encrypt the username and
password
)
07:22 09:03 SMTPD(000000A8) Authenticated lconrad,
session treated as local.
Imail trusts me like a "local" user, although
I'm coming from an untrusted ip address.
07:22 09:03 SMTPD(C7120086)
[212.73.210.79] MAIL FROM:<[EMAIL PROTECTED]>
07:22 09:03
SMTPD(C7120086) [212.73.210.79] RCPT
TO:<[EMAIL PROTECTED]>
07:22 09:03 SMTPD(C7120086)
[212.73.210.79] D:\IMAIL\spool\D4753086.SMD 1152
I don't think you're
client is suffering from SMTP AUTH failures.
Is whatever.com a
mailhost on Imail or elsewhere??
Side Note: Hey everybody, look
at that:
the SMTPD process that does SMTP AUTH is NOT the same
as the SMTPD process talking to the SMTP client!! If you stay awake, you
learn something everyday.
As I searched through that log file,
EVERY occurrence of "00A8" was followed by ") Authenticated ..." So I
guess when the SMTP AUTH function hangs, it's that specific "SMTPD AUTH"
process that isn't alive.
Is that right,
Ipswitch?
