sendmail test

Hi all,

We have a server sitting on the other side of the firewall. Should it be possible to do a telnet yahoo.co.uk 25 to confirm I can connect to the yahoo mailserver. I have tried sending a mail to a yahoo.co.uk account and it just seems to hang with no errros and I get no mail.

cheers

Re: sendmail test

Hi Adam,

Assuming you are using HPUX.
1. If your server is allowed as the known mail exchangers at yahoo, it should else it will fail with a denial message.

2. You can see where its hung with:


sendmail -v -d9.99 -d38.99 user-name@yahoo.co.uk < /dev/null

Re: sendmail test

Short answer: yes, it should be possible. That will tell you whether or not outbound port 25 is blocked by your firewall. It normally is.

HTH;
