Bet you all thought you'd heard the last of this! Not so. I'll try to bring everyone up to speed.
As you may or may not recall, we are unable to send mail to "pecandeluxe.co.uk". That domain is managed by Legend, whose mail exchanger is "mx.legend.co.uk"; whatever the problem is, any mail addressed to the domain "legend.co.uk" suffers the same fate as "pecandeluxe.co.uk". Basically, SIMS makes a valiant attempt to deliver the mail and gives up, finally returning a message that the "connection is broken". We have made numerous attempts to connect to mx.legend.co.uk via telnet etc. My isp says that Legend must be blocking us. Legend says that my isp must not be connecting properly. I even received this message: ----- Begin Quote ----- From: "Steve Wilson" <[EMAIL PROTECTED]> To: "Thomas Mangin" <[EMAIL PROTECTED]> Cc: "Darren Spink" <[EMAIL PROTECTED]> Sent: Thursday, October 10, 2002 8:24 AM Subject: Re: Undeliverable mail: E-mail status > This bounce was not generated by our mail server, looking at the headers > it's from a machine on an internal network (192.168.1.108) to a machine > which thinks it's called running (Stalker SMTP Server > 1.8b9d14), this machine seems to then be tring to relay through a machine > it's not allowed to, I still stand by my original reply that it's a problem > with the mail server "pecandeluxe.com" which I guess is configured to relay > through their old ISP, as even if they were connected through someone else > we'll deliver mail for @legend.co.uk. > > I did however find one problem ... > > $ telnet legend.co.uk 25 > Trying 212.69.224.224... > Connected to legend.co.uk. > Escape character is '^]'. > 220 www.legend.co.uk ESMTP Postfix (Release-20010228) (Linux-Mandrake) > helo kate.swsystem.yorks.com > 250 www.legend.co.uk > mail from: <[EMAIL PROTECTED]> > 250 Ok > rcpt to: <[EMAIL PROTECTED]> > 554 <[EMAIL PROTECTED]>: Recipient address rejected: Relay access denied > quit > 221 Bye > Connection closed by foreign host. > > It seems their mail server is using the A record for legend.co.uk and trying > to send the mail to that not the MX ...

I attempted to send mail via a different mail exchanger. I got a messages that indicated something was wrong at the Legend end: ----- Begin 2nd Quote ----- Failed to deliver your message to [EMAIL PROTECTED]: SMTP: Address rejected by host Host 'legend.co.uk' says: 554 <[EMAIL PROTECTED]>: Recipient address rejected: Relay access denied Reporting-MTA: dns; pecandeluxe.com Final-Recipient: rfc822; [EMAIL PROTECTED] Action: failed Status: 5.0.0 ----- End 2nd Quote ----- Now I read that to say that legend.co.uk rejected the message and would not relay it. But as you can see above, "Steve" categorically denies that their servers had anything to do with it. His "guess" that it is our mail server is also incorrect. My SIMS server is configured for direct connection... it does not connect to any other server for relay purposes (at least not now... see DNS info below). I included "Steve's" notes about the telnet session and the www mail for your consideration. If any of you see anything there that may be a clue to the problem let me know. Now, the last time I brought up this topic, Dan Brotsky delivered a LENGTHY analysis of my configuration, particularly as it relates to DNS issues. Dan has been gracious and kind to spend a lot of his time educating me about DNS and helping me fix my DNS records locally. In the course of this, we found a few interesting things. First, SIMS setup wants you to fill in a field called, "Main Domain Name". Imagine my confusion that this should NOT be "pecandeluxe.com"! According to Dan (and born out now by my experience", this should be "bigbrother.pecandeluxe.com". A simple router entry "pecandeluxe.com = bigbrother.pecandeluxe.com" tells SIMS what to do with the traffic it receives from my gateway router that is addressed to "pecandeluxe.com". Now, I suppose I could leave SIMS thinking it is "pecandeluxe.com", but based on my configuration, it seems unwise to do so. Dan may want to chime in here and clarify this. Second, it turns out that because my isp hosts "web-based" mail as part of their web-hosting package, they have a "lock" on "mail.pecandeluxe.com", "pop.pecandeluxe.com", "pop3.pecandeluxe.com", & "smtp.pecandeluxe.com". Isn't that special? No biggie, except, that my DNS records have always said that those hostnames were the same as "bigbrother.pecandeluxe.com". This MAY have been the source of some relay issues and perhaps some confusion as machines tried to send mail to both my server & my isp's server. So, I'm cleaning all of that out of my DNS records and changing all my mail clients to look for "bigbrother.pecandeluxe.com" for both SMTP & POP traffic. I've already fixed one client this way and attempted to send mail to "pecandeluxe.co.uk", but it is no-go, still. I have given up. Mainly because we have decided to move our subsidiary's email accounts onto OUR server. So, they will simply connect to our server and all the mail will be accepted. I just have to make their ip's valid clients... So, thus ends the saga. I still don't know why we can't exchange mail with legend.co.uk... but soon, we won't have to.
