How fast should MailListPro be sending out email ??

[john193]

Hi Dean,

This afternoon a tweak on EXIM finally solved the sending of email using SMTP recommended.  But now I want to make sure that the settings are
tweaked.

If I have 3500 emails to send out to a list. JUST how fast should it be sending the emails out from my server ?  My settings are as follows:

SMTP Server (Recommended) CHECKED
 Always write SMTP logfile CHECKED for now..
HOST: localhost
Port: 25
Reconnect every 1000 emails (DEAN what is the best settings here)
AUTH ? CHECKED
and
Authorize by Checking Email CHECKED

all with the appropriate fields checked. I also ran a test on the settings and they all past.

So I guess what I'm asking Dean is this ... throttling the
number of emails it's sending out to the REST of the world
so my IP is not blacklisted simply because I'm sending out
email TOO FAST!!

Are my settings OK or would you suggest a tweak here to
ensure deliverability ? If it takes another 5 or 10 who cares..
Deliverability is the key.

I await your thoughts on this most important issue.

Christopher,

Most servers will accept your email, even if sent quickly, immediately. Note that the time it takes to queue to the server is not necessarily the time it takes to finally deliver the message from queue.  Throttling options for SMTP are coming in the future (actually it's been discussed before and there is code available) but for now (and this is actually more efficient because PHP would not be executing forever) you might be able to tweak your mailer settings.  Unfortunately I am not an Exim pro (yet).  Try a google for "exim outbound mail rate" or "exim smtp throttling".  Note I also recommend the following optimizations for exim.

I use sendmail and get about 35,000 per hour or so on average queued from Listmail to the Sendmail Server ( which is seperate ).

SO it shouldn't take much more than 6 minutes or so to queue those to the mailer...

This really depends on server, etc.  I'd guess the mailer will make little difference with this small a number.
