I have a apache server installed on my system which I use for testing out stuff like wordpress and forums. I use the server for learning stuff only. I would like to know what do I have to do so that these blogs, forums etc can send an email when someone registers. I guess most of these use sendmail to send email. So how do I configure sendmail so that it sends email using my gmail address and smtp. Also I think there is a php mail option (or something called like that) that allows us to send email without having sendmail installed.

I'm configuring sendmail that runs on Linux Slackware but find some difficulties to do some quick startup due to its complexity and massive documentation. Suppose I want to configure a sendmail that can serve 2 domains:
ethereal1m.no-ip.com
ethereal2m.no-ip.com
I use noip2 client software to connect with noip server that translates the dynamic IP addressed domains, setups POP, and does forwarding. By having 2 domains, I want to able to send email between admin@ethereal1m.no-ip.com and admin@ethereal2m.no.ip.com;therefore, my machine acts as both a server and a client. How can I setup sendmail so that it acts as both server and client? How to register email address and its domain on sendmail?

I wanna configure RAID 1 within TWO HDD in RHEL-5 during installation moment .I have the following questions regarding software raid vs hardware raid :
1) What is the basic difference between hardware and software raid
2) In software raid , If I use two HDD as RAID1 , then if one HDD is failed , can I boot it from another HDD ?
3)In software RAID , Between two HDD , If One HDD is failed then if I remove bad HDD and add a spare HDD then is it automatically synchronized with FIRST HDD ?

5) Finally is there any documnets or sites where I get software raid configuration during INSTALLATION moment in using GRAPHICAL mode , plz give me the address.

I have running sendmail 8.13 on my red hat enterprise linux 5.1, but i have a problem. I can send a mail from my line command terminal to hotmail, gmail, yahoo and any of these, but i can't send mail to my own domain (mydomain.com), when i wrote a mail i get a reply from MAILER-DAEMON@localhost.localdomain that says that the message had pemanent fatal errors and shows as user unknown the mail was suposed to recive the message. For example, if i send one mail from user1@mydomain.com to user2@mydomain.com the user2 does not recive any mail, but that does not happens if user1 sends a mail to any hotmail address or gmail or any other. Besides i also can't recive on my server any mail to user1@mydomain.com or user2@mydomain.com (for example) comming from gmail.

Sendmail on the RHEL server is set up to forward email to company internal mail server (via SMART_HOST). This has worked fine for years.
From the server, doing a sendmail dave@company.com, the message is sent immediately. No problems - and no change here.
From the server, doing a sendmail roberto@compania.com (compania is the part of the company in Mexico) causes a 2m40s delay before sendmail does anything.
No packets are sent until after 2m40s wait. Message is always sent after the delay. It is not clear what the server is waiting for.
For *each* user in the @compania domain specified in sendmail command, an additional 2:40 is imposed before email is sent. Email is always sent after the n*2:40 sec delay.
Sending email to some_name@AnUnusedDomainNameThatDoesntExist.com is processed immediately - with a bounce email received in a couple of seconds.
Q: How do I determine where this 2m 40s delay is introduced?

probably this is trivial, can't find the right resource thou... i have ISP's provided email address and i configured pine to use ISP's smtp server. Which is all good, but if and when i need to send a big email - i have to wait until file transfers over the network - which is pain. How can i configure pine and sendmail(?) to use local's machine ( centos 5.2) sendmail(?) to be able to give the file to sendmail and continue to work in pine while it's working on actual sending of the file.

I'm trying to configure procmail for sendmail but its not working. I added these 2 lines to sendmail.mc:
define(`PROCMAIL_MAILER_PATH',`/usr/bin/procmail')dnl
FEATURE(local_procmail)dnl
So my question is, where do I put .procmailrc? An examples I found on the net has the procmailrc in the users mail directory, but there are no user mail directories on the sendmail server. It is used purely to relay mail to the Exchange server.

I am trying to set up sendmail on my intranet (home) webserver, so that it will send mail via my ISP. I have searched for similar threads including this thread, but the responses do not seem to have solved the problem. All I want is to call sendmail from Perl, to post myself the responses to a test form I am building, using my normal internet mail address. I do not want to receive or relay mail from any host except the web server itself (127.0.0.1).
I have edited sendmail.mc to define SMART_HOST as my isp's mail server and MASQUERADE_AS to be my local network name (which is not a registered domain - it is just the name I have given my home intranet). I have run make and built a fresh sendmail.cf, then restarted sendmail.
Using my form, I am able to submit the message to sendmail, but after 40 seconds the mail log shows a message

So I have two servers in my environment, I have an app server that runs my Java App on it and then I have a utility server. Right now, I have that utility server acting as a simple mail gateway so when my app server needs to send an e-mail out, it forwards it to the utility server and the utility server sends it out to where-ever it's destined to. The Java server always sends as one specific user, let's call it bob@company.com.
This set-up is working just fine right now. Now, I also have my company.com e-mail hosted at an e-mail provider for all of my user's e-mail accounts and such. I also have a bob@company.com e-mail account so if e-mails ever bounce, they end up in this inbox. Again, this works fine.
My app is pretty email dumb so it can't authenticate itself or anything, that's why I am using sendmail on my utility server instead of my e-mail provider's SMTP server. What I would like to do is to configure sendmail to forward all outbound e-mails (and authenticate) to my e-mail provider's SMTP gateway using the bob@company.com account and credentials. Is it possible to configure sendmail to do this?

It seems my sendmail (running in slackware 13.0) cannot send out emails correctly. I guess I need to tell it what is the smtp server to use. And, I heard, gmail's smtp server is available to use for this purpose. How to configure my sendmail this way?

I have setup CentOS 5.2 with Nagios to monitor my network and have that configuration almost done. I have also setup Sendmail to forward all mail (really only Nagios notifications) out to my Exchange server using define('SMART_HOST', 'exchange.domain') in the sendmail configuration file and it seems to be working correctly.is there a way to configure Sendmail to forward all mail out through my Exchange server as it is now but send mail out to the internet itself if the exchange server is unavailable, somewhat like a failover configuration.
