[AMaViS-user] can't keep up...
Setup is via dual-sendmail and latest amavisd. It seems that the ammount of spam received is too much and basically I have sendmail accepting more mail that it can process...

No immediate plans to switch to postfix (although this might change if we need to add support for spf). Would going to sendmail-milter help with this ? I might have to do RBLs if not (suggestions for this ?) Is there anyone with good experience in a dual setup that can provide some pointers with regards on setting up more restrictions on the sendmail-rx part of it ? Timing looks ok, with over 75% of it being SA which has some safe rules from the SARE ninjas and also Fred rules.

Our sendmail-rx takes everything (does have some rate limits in place) but do not do any RBLs nor username checks. We are still running the latest SA 3.0.x but will switch soon to 3.1.x. Rejecting mail addressed to nonexistent local users is paramount. I see two possible directions: add more servers to the mix, or go for greylisting. I still manage to do without graylisting, hope it stays that way, but it a single major tool to cut down the traffic reaching SA without doing too much harm. No immediate plans to switch to postfix (although this might change if we need to add support for spf). Mentioning SPF on a Postfix list is banned :) The future is supposed to be in DKIM, but there's still a long way to go. Would going to sendmail-milter help with this ? Not much. SA is the major burden, you can only escape it by not letting it see all the traffic (RBL, greylisting, rejecting mail to nonexistent users, sender address verification, ...) I might have to do RBLs if not (suggestions for this ?) RBLs impose higher risks of rejecting valid mail than greylisting. In my view RBLs only belongs into SA rules, otherwise one is putting (arbitraty) decisions into foreign hands with little control over it. Is there anyone with good experience in a dual setup that can provide some pointers with regards on setting up more restrictions on the sendmail-rx part of it ?

Since we forward the mail to the final mail store servers, would milter help in this regard ? Ie, would the message be denied since the destination server would rejected it as the user is unkown ? Don't know how that can be handled best in sendmail, I'm only aware of statical table of valir users. Likely there are other choices. With Postfix there are a couple of choices, like shared SQL or LDAP database of users accessible from all MX hosts, or if that is not possible, use of address verification probes, which query the next MTA if address is valid - this happens during original SMTP session and only if the answer is not yet in a cache. I believe milter now is mature enough and allows the addition of x-spam-status to the message, right ? You mean invoking amavisd-new through milter interface? I wouldn't recommend it, there are limitations in functionality and poor control on load, which can be fatal on an already heavily loaded system. I think I can get funding to get new hardware. Looking at a couple of Xeon Dual Core dual proc. boxes with more memory and 15K scsi disks. It is probably cheaper to get more of consumer grade boxes with SATA II disks then a single high-grade box. I wouldn't recommend this for MTA host, but I think it is perfectly acceptable for running amavisd-new + SA, as a loss of a host would not imply a loss of messages. SA is mostly CPU and memory hungry, somewhat slower disks don't matter that much. That's been my major concern. I do need to look more into greylisting though. Is this something possible on a sendmail-dual scenario or even milter? Also, what about adding a milter to sendmail-rx - is this possible ? You can attach milters to sendmail-rx, no problem. I'm sure there is a greylisting milter available, although I never bothered to look. Mark - Using Tomcat but need to do more? Need to support web services, security?

If they send DSN messages that also provides verification, if they silently discard the messages you could just as well do that in sendmail-rx. Since we forward the mail to the final mail store servers, would milter help in this regard ? Ie, would the message be denied since the destination server would rejected it as the user is unkown ? You don't need milter for that. All you need is virtusertable in sendmail-rx with all known addresses and wildcard, which can either reject or discard unknown addresses. Easy, fast and efficient.
