[plug] Email problem

[Bret Busby]

Hello, everyone.   
   
Further to the messages that I have so far posted about   
this, I have logged into the "webmail" at WASP, and, in   
going through the mail that has arrived at the ISP for us,   
but which has not been downloaded to us from the WASP mail  
server, I have noticed in the   
headers of some of the emails, the line  
"X-Diagnostic: Possible loopback problem";   
an example is in the following header, from a message  
sent by the mailing list administration software, 
SmartList, of one of the mailing lists that I administer.   
  
Please also note the third line of the header, which  
indicates that the message was forwarded by me, at 2240  
last night (which happened to be after our dialup  
connection had been terminated by the ISP, and, when we  
were not connected). Note also, that the fourth and fifth 
lines of the header, in conjunction with the third line, 
apparently show that the message did not go anywhere from 
WASP itself - it was not downloaded, but forwarded in a 
loop, by WASP itself, one second after the message arrived 
at WASP, given that we were not connected at the time that 
this occurred.

In the context of the above, could someone please advise  
as to whether I am correct in my perception that our ISP  
is messing up our email, by whatever changes the ISP  
implemented yesterday, when this started, and, if I am 
correct, does anyone have any idea as to the cause?  
 
A few minutes ago, I spoke to the suppport person at the 
ISP, with whom I spoke earlier today, about this, and, 
after a number of hours, the ISP has no idea as to what is 
going on, or why. 
 
I have today checked the filters that are and were in 
place at the ISP, on our email account, which filters had 
mostly not worked until the changes to the email system at 
the ISP yesterday, and, none of those filters would have 
done any forwarding like this. 
 
Regarding the "X-Diagnostic" line that refers to the 
loopback, the rootsweb helpdesk web site has the 
following: 
 
"X-Diagnostic: Possible loopback problem  
 
This may be seen where SmartList thinks that mail is going 
in a circle rather than being delivered.  It rarely 
happens but it may be the case, some administrators may 
see this more often than others if they have an ISP that 
may be more prone to loop mail. " 
  
So, I assume that some change made to the mail system at 
WASP yesterday, has implemented the loopback problem. 
 
Thanks in anticipation.
