Sendmail / AIX 4.3.3 nodes in SP2 1

[scotbuff]

I know there is a sendmail forum, but I think this may be more of an AIX related question. We noticed that when sending mail from the command line via sendmail using the following command that there is roughly a one minute delay from servers residing inside the SP2 complex:

echo "test"|sendmail -vt scotbuff@company.org

Servers outside the SP2 complex send the mail immediately upon hitting the enter key. We are using sendmail 8.9.3 that ships with AIX 4.3.3 with an configuration file of 8.9.3, the output from this command is identical, no warnings no errors. We do not feel the cause is anything to do with sendmail, but rather the fact that it is sending from within the SP2 complex.

Does anyone have any ideas on what setting is causing this minimum of a 1 minute delay before sending the mail? Thanks in advance.

Starting under AIX 4.3.0, if you place a "." after the servers hostname in /etc/hosts, this problem goes away. I too experience it - and this is the fix as of 4.3.0 from IBM.

Just put a "." after the hostname - see below

10.124.17.5 hostname
10.124.17.5 hostname.

Make it like the second entry.
