G'day,

The Solaris guys bounced a couple of machines last Friday and now the utl_smtp email facility, on these machines only, is not having its messages delivered.

Anyone have an idea of which facility on Solaris they forget to restart?

G'day,

I ran the following command:

svcs -a | grep -i mail

and received:

online         Oct_15   svc:/network/smtp:sendmail

telnet <mail_server_host> 25

above should result in you getting SMTP prompt

netstat -a | grep 25

is mail_server actually listening on port #25?

@BS,

I tried the second one first and it produced no output:

bash-3.00# netstat -a | grep 25
bash-3.00#

I then tried the first one:

bash-3.00# telnet xxx.xxx.80.154 25
Trying xxx.xxx.80.154...
Connected to xxx.xxx.80.154.
Escape character is '^]'.
220 ldom-xxx-dev-tst.localdomain ESMTP Postfix
^]
telnet> quit
Connection to xxx.xxx.80.154 closed.
bash-3.00#

I tried the second one again:

bash-3.00# netstat -a | grep 25
acid-xxx.47257   taaa.yyy.zz.au.1984 49232      0 131768      0 TIME_WAIT
acid-xxx.47258   acid-xxx.1521    139060      0 139060      0 TIME_WAIT
bash-3.00#

@BS,

I did the "telnet <mail_server_host> 25" on two machines that work and two that do not. They all appeared to connect. They had different results for 'environ list'. A working and non-working machine were nearly identical. Each pair working or non-working are quite different. Weird.

@BS,

Thanks for the help. There is a problem on an intermediate machine and another group of people will have to look at it.
