Interesting Domain Issue

[dogstar1]

This seems to be a weird one. When I send a message to a particular email address it appends my domain to the end causing an error: "Too many "Received" headers - suspected mail loop"

An example is: intent - send a message to user@foo.com What happens: message is returned and the address was changed to user@foo.com.bar.com (bar.com being my domain)

Any ideas on this one?

Thanks!

puh... that won't be sooo easy I believe! ;-)

some questions:
1. assume the address you're trying to send to is outside Scalix, so it is not an address connected to a local user?
2. are you using properly set-up DNS? If yes, what does
"dig foo.bar MX" return?
3. did you do any special configuration build on your sendmail?
4. what entries to you find in your maillog file?

Thanks,
Florian.

Correct

2. are you using properly set-up DNS? If yes, what does
"dig foo.bar MX" return?

I can dig www.foo.com but not foo.com...

3. did you do any special configuration build on your sendmail?

SmartHost

4. what entries to you find in your maillog file?

No obvious errors. The To: header is changed from user@foo.com to user @foo.com.bar.com

I believe this must be DNS related....

two reasons....

1. sendmail canonifys domains using DNS, so if there are any aliases or so setup, it will use them.
2. in DNS, it is quite simple to omit a "." at the end of a config line which will add the "current domain" to the end of the name. Your name looks much like that.

So, assuming you don't give the real domain names here... :-) are any of those served by your own DNS server?? ;-)

so you should possibly be doing

nslookup
set type=all
foo.com

what type of records to you get back??
