[IMail Forum] Send mail problem

[David Barrett]

Hello all,     This is a new one for me. I have been getting calls about mail not making it through a local ISP to users, I get a 550 Access denied error. I have added a snip of the log. As you can tell I can send other places or you would not be reading this. I would like to know what is going on. The staff at cybertours.com claims nothing is amis and may not be even though they just moved thier whole mail, dns and web services to another location. Can any one tell me what is happening during the below transaction ? And I can send myself an email addresses to my cybertours account from my cybertours account. Am I being blocked by them ?     12:14 08:54 SMTP-(00000CFC) Trying cybertours.com (0) 12:14 08:54 SMTP-(00000CFC) Connect cybertours.com [205.139.4.7:25] (1) 12:14 08:54 SMTP-(00000CFC) 220 transporter.cybertours.com ESMTP Sendmail 8.9.3/8.9.1; Fri, 14 Dec 2001 09:04:09 -0500 (EST) 12:14 08:54 SMTP-(00000CFC) >EHLO maineconnect.net 12:14 08:54 SMTP-(00000CFC) 250 transporter.cybertours.com Hello warpdrive.maineconnect.com [63.88.217.210], pleased to meet you 12:14 08:54 SMTP-(00000CFC) >MAIL FROM:<[EMAIL PROTECTED]> 12:14 08:54 SMTP-(00000CFC) 550 Access denied 12:14 08:54 SMTP-(00000CFC) ERR undeliverable 550 Access denied 12:14 08:54 SMTP-(00000CFC) SMTP_DELIV_FAILED 12:14 08:54 SMTP-(00000CFC) >QUIT 12:14 08:54 SMTP-(00000CFC) 221 transporter.cybertours.com closing connection 12:14 08:54 SMTP-(00000CFC) Creating message from Postmaster 12:14 08:54 SMTP-(00000CFC) finished D:\IMail\spool\Q04ae202.SMD status=2   David Barrett Maine Connect, Inc.
