I have been tampering around with sendmail for the past one week and seem to make little progress. Given below is an abstract of the issue.
I have a Fedora 12 server(A VM on vitual Box bridged with a Windows XP host) which has to act as a SMTP server and have accordingly put up the loopback address[127.0.0.1] as SMTP relay.[I have also started the sendmail service.]
The server is in my office LAN.
When i send a mail the output is as below:
The /var/spool/mqueue show the mail as delivered and queued.
But i am not receiving the emails in my inbox.[Have checked spam/junk also]
I checked in google and was asked to put the below entries in sendmail.mc and compile the macro again.
The above entry has also not solved the issue.
Please let me know what the issue could be.Any help is greatly appreciated.
Thanks
HG

I need to add this also:
If i view the contents of queued file,i get the error "MDeferred: Connection refused by alt4.gmail-smtp-in.l.google.com."
Are you married to sendmail? I'd seriously suggest Postfix for several reasons including Postfix's better privilege segmentation as well as the easier to use config files.
I understand that postfix is a better tool. But since i have prior knowledge(whatever little) of sendmail and since i am on the brink of getting it configured,i thought i would go ahead with it. Once the sendmail issue is resolved,i will start looking at postfix.
I have neither of these configured(Reverse DNS and SMART_HOST)...Infact the machine i am working on is a standalone server not in any domain.
Suppose that i configure both,will smtp-gmail start accepting my mails? If so what is the security that smtp-gmail server has against spammers.How exactly are the smtp servers protected against spammers if all it requires is a SMART_HOST and reverse DNS lookup.
Am asking this to understand the E-Mail setup. I read in howstuffworks.com and got a little understanding...But this thing perplexes me..
Defining SMART_HOST and creating an access database allows sendmail to authenticate each email you send with your account username and password, just like any individual user, though it does it automatically.
BTW, here's a blog that talks about setting up sendmail to send mail.
Dear All ,
I have some problem in Sendmail , where it was sending mails perfectly fine with the Ip address of the client machine.
But suddenly there was an issue , the SMTP takes the IP of the bond1 interface.
So the IP could not get validated in the relay server.
So how should i send... (1 Reply)
