Delivery of email - maximum number of receipts in batch

Hi,

We have a windows dedicated server that we use to host our websites and as an mail server for our outgoing and incoming mail.

We recently sent out an email newsletter to a distribution list of about 8000 email address, this created a massive mail queue and delayed our client’s emails. It also seems some of the recipient’s didn’t receive the newsletter.

Is there a limit on the number of emails hMAilServer can handle in one go?

I noticed that the maximum number of receipts in batch option is set to 100, what is the maximum you recommend this be set to.

Thanks in advance

Wayne.

Depends on what hardware/connection you have, and what time you are prepared to wait. you can have 10000 recipients if you want, it will just take a long time to send it.

Ignoring the info about ASP scripts but focusing more on my replies.

HELP: Big distribution list are blocked by others servers

Hello,

I've also a distribution list wih 9000 members (opt-in). I've noticed that many of recipients won't receive the newsletter because their SMTP server refuses a big number of emails coming from same domain. They consider me as a spammer...

How can I configure Hmailserver to send the newsletter in batch, example, 100 mails/minute ?

I read that tarpitting is for this, but to block spam from others, not to bufferize outgoing mails

Thank you

Thomas

I got around this issue by queueing up my outgoing email with PHP in my MySql database then pulling 250 messages every 5 minutes with another PHP script and pumping them into hmail.

too complex in my case. I'd like to have this feature in Hmailserver.

Is this possible ?

does it exist a small SMTP relay that will play the role of buffering to be placed between Hmailserver and internet, for outgoing mail ?

What kind of SMTP server (perl, windows...) can do this ?

any idea ?
