Sending ~13.000 Mails - stops sending at ~1.300

Post by aschoenf » 2010-03-12 10:16


I have yet another strange problem (don't know if it comes from the hMailServer).
I'm sending out ~13.000 newsletters for a customer with an Webservice, but it always stops arround 1.300 mails (+/-100).

Now my question:
Is there any limit like max. messages (don't think so because of the difference) or time limit for an SMTP session?

Thanks in advance :)

Best regards,

No to both your questions. More likely your web asp script is timing out.
If at first you don't succeed, bomb disposal probably isn't for you! ヅ

A word of caution here. If you're sending out mass mails you might risk getting yourself placed on a spam blacklist, especially if you have a static IP address.

If this is a regular thing, I'd suggest finding alternatives for your mass mails. The company I work for, for example, does its mass mailing via a DotMailer account, specifically so our public IPs, which handle our emails amongst other things, don't get listed as spam servers.

Hello aschoenf, if You are using ASP - Classic or .Net - You must take care for the timeout of Your script!
I send every month a newsletter - with classic ASP - to about 20.000 recipients with no problems.

Kind regards :)
