Elgg uses the standard PHP mail() function. What did you want to set?

hello the notification mails from my elgg site are not going which may be because of the fact that mail server is not configured with sasl.Is there any other solution to the problem as I am not good in configuring the mail servers.

there is a thread on this from just a couple of days ago here:

Hey thanks for the help but what about the plugins which bypass this system like the invite friends plugin or the openId clent.

I've said this before but I'll say it again: it is a bad idea to hack Elgg apps to support server specific email requirements.

A good hosting provider will properly configure email on your server for you. A server which prevents PHP's mail() command from working properly is a broken server in my view. If you are forced to do this yourself, you will need to learn about the PHP/MTA interface.

Hi actually I am testing elgg on my local computer by using dyndns for nameserver update and sendmail as MTA.The problem was with the fact that I had not been able to configure sendmail properly.Anyway I completely agree with you its a bad idea to hack elgg applications.

no emails sent from elgg,

No question or details in your statement.

If emails are not sent it's very likely a server issue because Elgg does fully rely on the server's capabilities on sending mails and normally you wouldn't have to set up anything in Elgg for emails to be sent. Actually there are no configuration options for mail sending in Elgg anyway.

Test out, if sending of mails work on the server (as described on the second link). You might also want to check if it's only verification mails that seem to be missing. For example you can create two test accounts and send a private message from one account to the other (email notifications in the user's settings enabled). If this notification is sent then the missing validations emails are likely to get blocked by ISPs because they are assumed to be spam. In this case you need to figure out what the possible problem is (there could be various reasons). In this case you might ask your hoster for support.
