sendmail auth/ident checking issue

Hi All,

I have a problem sending mail to a host which seems to have sendmail configured to use Ident port (113) to check back on the mail sender.

My problem is that this port is not enabled on the firewalls between sender and receiver so the ident checking and hence the mail is failing and I need to turn this checking off.

I modified to include an ident timeout "O Timeout.ident=0s" which I believe is supposed to eliminate this checking yet firewall logs indicate it is still happening.

I can telnet the server on port 25 and have dialogue with the mail server and even supposedly leave a mail though when I try to check it on the host it says there is none.

Any advice on how to get the mail through - particularly any more settings - would be greatly appreciated.

local.users(4)						     Kernel Interfaces Manual						    local.users(4)

local.users - Specifies mail recipients on the local host. DESCRIPTION
The local.users file contains a list of user names whose mail is to be delivered to the local host and whose return address is user- name@hostname. Entries in the local.hosts file are in addition to other local users (such as root and postmaster). See for a description of other local users. You can add entries to this file if the host is configured as a simple client and either of the following is true: The user wants their mail delivered on this machine rather than being forwarded to the mail server. You are adding aliases to the /var/adm/sendmail/aliases file. When the host is configured as a simple client, the alias must be added to this file and the aliases file. A simple client is defined as a host that had the mail system configured using the MailConfig application from the System Management utili- ties or configured using the mailsetup utility's Quick Setup menu. The format of the file is as follows: User names are separated by blanks or new lines. Multiple user name can be specified on a line. Blank lines are ignored. A comment mark (#) ends the line. After modifying the local.users file, you must restart the sendmail daemon to apply the changes. Use the following command: # /sbin/init.d/sendmail restart EXAMPLES
root postmaster rw # A comment followed by an ignored blank line. # Another comment. mariah # Another comment. carey # Leading blanks are acceptable. FILES
Specifies the path name for the file. RELATED INFORMATION
