Fellow list managers,
I have just brought a very large mailing list (~10000 subscribers,
firstname.lastname@example.org, Brock Meeks' CyberWire Digest) into production here,
and am unsatisifed with sendmail's delivery speed. My main problem is
that sendmail only uses one process per message to deliver mail, which
I find to be suboptimal for a list of this size. One option I have would
be to use qmail, but I would prefer not to do that for several reasons.
One solution that has been suggested to me is to use a helper program
called bulk_mailer.pl, which breaks large lists into 'bite-sized chunks'
for sendmail to deliver. Unfortunately, I have been unable to locate
this tool. Is anyone familiar with it, and knows where it can be found?
