sendmail appends RDPT To: domain.com with another domain.com

[Bob_165]

Here’s a weird one. This is a new HP-UX server running HP-UX 11i2

echo test | sendmail -v name@domain.com

name@domaint.com... Connecting to mail.domain.com. via relay...
220 mail.domain.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.3959 read

As you can see, when it gets down to RCPT To: it adds a second (same) domain.com. So of course now it won’t send it.

I’ve looked at my resolve.conf and my sendmail.cf and sendmail.cw

Anybody have any other clues??

Hello,

Who manages the DNS for domain.com. Is it,
by any chance your own domain?

a) If so, check your DNS. Errors in zone
configs create these kind of problems :)

For example, what does this command report:

nslookup somehost.domain.com

b) Second possibility, is domain.com
accepting wildcard MX resource records?

If so, add an option to DNS Search options.
Specifically, add the following to
sendmail.mc file:

define(`confBIND_OPTS',`-DNSRCH HasWildcardMX')dnl

Cheers,

The DNS displays correctly (no double domains)

I think you might be on to something with the MX record. The company changed domain names awhile back, but I believe they still have some remnants of the old domain and allow members of the old domain to function.

I looked in the /etc/mail and I can't find a sendmail.mc file.

Maybe youâ re thinking sendmail.cw? I thought that was just for hostnames.com etc..

Please let me know...thanks!

Shalom,

HP-UX relocates the sendmail.mc file and gives it a slightly different name.

See this script for file locations.

Script is usable BTW

Here's some more info...

I changed the HP systems domain from domain.com to just domain.
Now it works like if should!

..But I don't understand why.
