Re: [xmail] Speed
Hi Sabahattin, It's been like donkeys' years since I've used an MTA other than XMail. I've been using XMail for nine years now (going for a decade) and never had any problems. That's why I don't drop it. It's a rock solid MTA. Concerning speed, I don't know. But I would safely bet that XMail is up there, either first or second with the rest of the MTAs. Just my opinion, s. - I merely function as a channel that filters music through the chaos of noise - Vangelis From: m...@sabahattin-gucukoglu.com Date: Sat, 30 Jan 2010 12:25:51 + To: xmail@xmailserver.org Subject: [xmail] Speed Hi all, By all reasonable accounts, XMail is fast. Does anybody know how it stacks up against the competition? Postfix, in particular, has held the speed crown for a good while now. But XMail with this fast thread startup and connection reuse could, I'm sure, be made to outflank Postfix even under stress and with its connection cache enabled.

Here on my minimal server it's filters that take most of resources by orders of magnitude I'd guess. That is indeed what todays is the limiting factor of MTA's performance. Pretty much everyone runs some sort of filters, checks RBLs, and so on, which end up limiting performance far more than thread pooling and connection caching. Unless you use an MTA which run no filter, which perform no DNS resolution, which does no RDNS checks,, which checks no RBLs, and so on. - Davide ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail

Unless you use an MTA which run no filter, which perform no DNS resolution, which does no RDNS checks,, which checks no RBLs, and so on. That might be an ideal relay-only site, actually. If you had multiple MTAs, you could devote those with fewer such checks to outbound-only deliveries, mailing lists in particular. Then, spending as little time wasting remote SMTP startup/shutdown and new processes probably makes much more sense. I've already optimised DNS using large local caches, and would be willing to do almost no checks on client deliveries, only inbound SMTP server sessions. Those are always slow, because of authentication, TLS, mail processing, etc. Cheers, Sabahattin ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail
