[cobalt-users] PHP mailing list on RaQ4i 256

["Si Watts" <simon@xxxxxxxxxxx>]

Hi all,

One of my site clients has managed to collect just short of 5000 email
addresses from his customers when they have made purchases in his bricks and
mortar store. He wishes for me to write him a mailing list program to manage
these addresses and enable him to send a marketing message to each one of
them in turn, quickly and easily (the same message to all addresses).

I guess my question is to whether PHP would be allowed to actually deliver
that volume of mail to sendmail before the script times out (still set to
default 30 seconds AFAIK)?
Addresses will be stored and retrieved from MySQL db. Essentially would the
script sending 5000 emails to sendmail in one drop cause it to crash/lock or
would only a proportion of the messages ever arrive at sendmail due to spool
size limitations?

Similarly would sending this volume have other detremental effects on the
overall servers ability to do it other tasks?

I'd appreciate any insights as to the current capacity of the sendmail
spool, and how many emails I can realistically expect my script to be able
to send in one pass.



Kind Regards
