Hi, using hMailServer and RoundCubeMail RC2 on Win2003 Server. I've determined I can send email from other applications, just not RoundCubeMail.
I did an hMailServer trace of an unsuccessful RoundCubeMail send and a successful other app send.  Here's the log:
UNSUCCESSFUL:"SMTPD"	"SENT: 220 Welcome To xxx.com"
"SMTPD"	"RECEIVED: HELO biggest"
"SMTPD"	"SENT: 250 Hello."
"SMTPD"	"RECEIVED: MAIL FROM:<<[email protected]>>"
"SMTPD"	"SENT: 250 OK"
"SMTPD"	"RECEIVED: RCPT TO:<[email protected]>"
"SMTPD"	"SENT: 550 Delivery is not allowed to this address."
"SMTPD"	"RECEIVED: QUIT"
SUCCESSFUL"SMTPD"	"SENT: 220 Welcome To xxx.com"
"SMTPD"	"RECEIVED: HELO biggest"
"SMTPD"	"SENT: 250 Hello."
"SMTPD"	"RECEIVED: MAIL FROM:"
"SMTPD"	"SENT: 250 OK"
"SMTPD"	"RECEIVED: RCPT TO:"
"SMTPD"	"SENT: 250 OK"
"SMTPD"	"RECEIVED: DATA"
"SMTPD"	"SENT: 354 OK, send."
"SMTPD"	"SENT: 250 Queued (0.000 seconds)"
"SMTPD"	"RECEIVED: QUIT"
"SMTPD"	"SENT: 221 goodbye"
The difference:
RoundCubeMail sent this:
"SMTPD"   "RECEIVED: MAIL FROM:<>"instead of
"SMTPD"   "RECEIVED: MAIL FROM:"I think that's the problem, any ideas of how to get rid of the double << & >>?
Thanks,
Ron
