What is MDA (fetchmail) and MTA (sendmail)?

Wait until all jquery ajax request are done?

I have an array with an N size. Each element of the array needs to loaded via ajax using jquery. I have the loading logic complete, I am just trying now to figure out how to load only 10 (formula should be able to handle changing this value) at a time, when the 10 items complete loading via ajax, load the next 10. Here is my example.

I have 100 elements of an array, the first 0-9 items need to be loaded, when those 10 items are done, 10-19, then 20-29 and etc. I am trying to get this to be efficient as possible, thanks for any help.

Though this may be totally off, I am hoping I am getting my point across to receive any help.

//Formula calculation
while(wait till count is complete){

}
function LoadBatch(array){
$.each(array,function(i,item){
$.ajax({
success:function(){
//Maybe a counter here to let loop know when to kick off next batch.
}
});
});
}

Solution 1

MTA - Mail Transfer Agent - sends and receives email between MTAs and among other elements of an email system

• Postfix
• Sendmail
• Exim

MDA - Mail Delivery Agent - receives email from an MTA for delivery to a mailbox

• procmail
• dovecot
• Courier

MUA - Mail User Agent - email client

• Thunderbird
• elm
• Exchange

Here is an overview of how the elements interact.

Solution 2

when you are talk about mta -it is mail server side role;

when you are using apple mail - it is client, and use smpt/pop3/imap/or other client protocols, but i think it is not mta or mda

You call Fetchmail a MDA, but it is really a MRA (en.wikipedia.org/wiki/Mail_retrieval_agent). Just mentioning for future searchers (:

It would have even great if you would have included squirrel AtMail...

@user53864: I listed only a few popular examples. For (perhaps) exhaustive lists, see List of e-mail clients (MUA) and List of mail servers (MTA and MDA).

Thanks. Great start to the answer I was looking for. Cool plugin btw.

Is it the case that an MDA runs IMAP to store the email, and the computer running the MDA also runs an SMTP server to receive the email from the MTA?

client = MDA :)
