Re: Repoint the sendmail relay-host to <new host>

I did some further digging and i find the current relay servers are set up in hostname.m4 file. How do i get the new relay host information in that file? Please help as i have worked only on HP-UX and not TRU64.

Thanks

Terry

Re: Repoint the sendmail relay-host to <new host>

Hi Terry,

You'll probably be best just using the "mailsetup" command to configure the new relay. This should generate the sendmail.cf for you...

Cheers,

Re: Repoint the sendmail relay-host to <new host>

You should use mailsetup, but if you want to change your mail host, you should search and replace using vi the /var/adm/sendmail/sendmail.cf file.

You will see lines like this:

R$*<@$*$N>$* $#smtpl $@mail.domain.com.py $:$1<@$2$N>$3 our domain; gw

# Parent domain
#
R$*<@$*$P>$* $#smtp $@mail.domain.com.py $:$1<@$2$P>$3 our domain; gw

# Nonlocal mail
#
R$*<@$+>$* $#smtp $@mail.domain.com.py $:$1<@$2>$3 use gateway


What you should do is to run in vi

1,$ s/mail\.domain\.com//newmail\.domain\.com/g

Dots should be scaped with backslash as they are regular expression symbols.

Here is what i have from my /var/adm/sendmail directory.

The current mail servers seems to defined in vista1.m4 file (as i cat for the mailservername in that file it shows up). in this case should i change the hostname.m4 file? (vista1.m4)

Thanks

Re: Repoint the sendmail relay-host to <new host>

Ivan/All

I have checked the sendmail.cf file and the mail.doamin.com defined is our dns server as in

Parent domain
#
R$*<@$*$P>$* $#smtp $@mail.domain.com.py $:$1<@$2$P>$3 our domain; gw

when i grep for the current relay host in vista1.m4 file (vista1 is the hostname) i get the current mail relay hostname. so it looks like i should change the vista1.m4 file. how do i change this file? is this generated by mailsetup?

Thanks

Send some e-mail, and see if it arrives?

If it does, look at the headers to see if it
passed through the expected systems.

man mailx
