I've this problem very often. We use SMTP AUTH for external workers to get
the mail. Once SMTP AUTH fails, all my internal clients can still send the
email. Only fails auth. But I have to stop SMTP service and restart to work
properly with auth.

Asunto: Re: [IMail Forum] smtp auth
For those you who seen it in all it's glory, there a byte-by-byte log from
Eudora PRO 4.3.2 with SMTP AUTH using CRAM-MD5 encrytpion, where "sv" is my
workstation:
257 64:0.17 Rcvd: "220 X1 NT-ESMTP Server ms1.meiway.com (IMail 6.03
10412-1)\r\n"
257 32:0.17 Sent: "EHLO sv.Go2France.com\r\n"
257 64:0.17 Rcvd: "250-ms1.meiway.com says hello\r\n"
257 64:0.17 Rcvd: "250-SIZE 0\r\n"
257 64:0.17 Rcvd: "250-8BITMIME\r\n"
257 64:0.17 Rcvd: "250-DSN\r\n"
257 64:0.17 Rcvd: "250-ETRN\r\n"
257 64:0.17 Rcvd: "250-AUTH LOGIN CRAM-MD5\r\n"
257 64:0.17 Rcvd: "250-AUTH=LOGIN\r\n"
257 64:0.17 Rcvd: "250 EXPN\r\n"
257 32:0.17 Sent: "AUTH CRAM-MD5\r\n"
257 64:0.17 Rcvd: "334 PDMxNjBtczE+\r\n"
257 32:0.17 Sent: "bGJZCVNDE5YjAwMmI4ZGI1ZGQ3\r\n"
257 64:0.17 Rcvd: "235 authenticated\r\n"
257 32:0.17 Sent: "RSET\r\n"
257 64:0.17 Rcvd: "250 ok its reset\r\n"
257 32:0.17 Sent: "MAIL FROM:<[EMAIL PROTECTED]>\r\n"
257 64:0.17 Rcvd: "250 ok\r\n"
257 32:0.17 Sent: "RCPT TO:<[EMAIL PROTECTED]>\r\n"
etc, etc,
I have of course deleted big chunks of the two lines following
Sent: "AUTH CRAM-MD5\r\n"
to maintain the security of my logon.
Unfortunately, I'm one of the post-6.03 SMTP AUTH patch users fortunate NOT
to have the seen the pb.
But if you're game, when your server quits AUTHing, then the above is the
sequence you use when you telnet in to see how Imail is not working. If
you had a log such as above, you could even copy/paste the encyrpted bits
into your telnet session, I think.
Is the master SMTPD just dead and no further SMTP processes are spawned, or
is it just a SMTPD process that hangs while doing SMTP AUTH?
So if anybody knows how to script a telnet session to test smtp auth for
failing so it can be restarted by some automatic process, the above is your
guideline.
