sendmail not able to send mails to outer domain
I am trying to configure a mail server for my company since, last week. And now, this thing is driving me nuts.
I hav tried with Postfix and Sendmail, but the error is similar for both, as both are not helpful to send mail to outer domain, like yahoo or gmail.
i hav read zillions of forums and articles of doing that. Now my manager is ultimately asking to replace the OS, as I am using centOS, and not willing to replace it for this mare issue.
Can anybody suggest wat to do, or replacing the OS is the ultimate solution...???
i hav installed DNS server as well, but don know if MX records are set, as i made an entry of MX record to named file, it gives error, by rejecting the change made. Do it really effects the configuration???
I am Newbie to the Linux world, and tried and installed all the required
applications on my own,by using GOOGLE the gr8. But this thing is really messy, as it shows no sign of mercy:-(
Any kinda help wud b truely appreciated, n plz don mind if i wrote anything annoying in anyways,as i am highly irritated over it..
