I can't possibly dispute this, but I would be interested to hear about some genuine problems with Amavisd-new or variants. I have an extremely low mail volume, but since I figured out the permissions I haven't touched amavis for quite a few months. Based on this kind of comment I am wondering if I have forgotten something important...?

(When the permissions were wrong I got a very strange intermittant problem though, timeouts and other strangeness. Easy to understand if you look at the process, however, a bit odd when initially installing. Depends how you look at this kind of problem, most other systems don't let you setup mail server, virus scanner, email processer, etc ALL as different users...)

Happy to take this offline if you think more appropriate, but interested to hear what kind of problems people have run into.

Thanks

Ed W

Yes, I have tried Amavis with many av scanners. I just tested Amavis-new and still do not believe that it is efficient as some of the commercial products. I am not comfortable with recommending Amavis beyond low volume non-commercial installations. Sure I know of people using it and they have had some success but I can tell you that they all have to tend to it for about 1-3 hours per week. As the volume and service levels go up the time spent per week also increases using non-commercial "free" solutions. This is fact that we have observed over and over again.

I do not recommend software solutions that increase a sys admins time or attention.

In many instances I have replaced "free" antivirus solutions in the past year with commerical products and have had our customers tell us that the commerical antivirus solution has paid for itself in time savings and availability and even improved customer retention (aka customer churn if your an ISP you know what I mean :-)
