![]() ![]() "Screaming fast" it may be, but these days that's not enough. It looks like what it is - An old app, patched up to try and look like something that's current. Instead of a full interface redesign/rebuild for OS X they just slapped in a few nasty looking generic icons and that was that. Finally, I can't finish without commenting on the interface - It has always been horrible, but now it's even worse. There are so many things wrong with it that there is not space to list them all, but suffice to say that so much of what a modern day mail client should be is simply missing, or implemented in a half arsed way. In the old days it was passable, but these days it is struggling to keep up, and has been for years. They just need to listen to their user base here and on their discussions a little bit more. But I so much wish CTM would make PowerMail a more modern and competing app. And there could be so much more to PowerMail, than 'only' maintaining the app, but thanks for keeping it alive anyway. They are there somehow and they show up, when problems arise (seldom enough), but there is more to support than only putting out fires. ![]() I never had problems with PowerMail, this app runs not only very fast but also absolute stable here for years. I have supported users of Apple Mail and Entourage for years and to me PowerMail is the one app I trust the most, when I think back about database problems I worked on. Though I agree, that the database limit of 2gb can be a limitation, I see myself not approaching that limit for the next ten years with 9 years of email already behind me.ĭatabases need mantaining and I cannot follow the complaints here. The attachments are stored external and not within the database. I just love how fast it start's - boom and it's there -, how fast it executes my many pop-accounts and I especially like the great search engine. Provide a smooth migration experience to users of Microsoft Entourage, Outlook Express, Claris Emailer and Netscape Communicator 4.x.Support advanced Mac OS 9 technologies as well native multi-tasking and memory protection on Mac OS X.Excel in supporting multi-lingual, world-wide mail using Unicode standards.Evolve our code base on a regular basis to meet customer needs.Contribute to the on-going diversity of mail clients on the Mac.Design and implement a clean, robust Macintosh user-interface with best-of-class Mac OS X support.Acknowledge the importance of our user's data accesibility by offering reliable storage, high-speed indexing and the ability to export to a variety of standard formats.Establish a lean, mean and efficient alternative e-mail client for people who care about e-mail.Version 1.PowerMail is built on top of the PowerMail Engine, a robust cross-platform foundation encapsulating 11 years of messaging and directory experience, PowerMail is continuously enhanced with the following objectives:.PowerMail can best be thought of as mail hosting where adding a new mailbox consists of a single SQL insert statement. Messages can live on multiple machines simultaneously and redundantly. PowerSMTP and PowerPOP do not access the disk directly - they contact the backends for that purpose. SMTP and POP daemons can be on different machines than the messages. There is no reason to configure which domains PowerMail is to host mailboxes for. All user data is always read from the User Base, which is typically a relational database There is no mapping between mailboxes and operating system users. It is best to not compare PowerMail to traditional mailhosting solutions as this can be very confusing. On operating systems supporting this, sendfile() zerocopy TCP features are exploited for maximum throughput. Retrieval works the same way, in reverse. ![]() Either email is accepted or it is not - there is no way for the system to get jammed with incoming email. There is no queue, email is never bounced. Once, as well as multiple smtp servers, all talking to the same pool of Besides distributing messages over multiple machines,Īdditional copies can be stored, leading to very high redundancy.įurthermore, it is easily possible to have multiple pop servers online at Distributed message hosting means that additional machines can be added on the fly without moving files around or growing filesystems. If a mailbox is listed in the userbase, it works.Ībility to scale. No /etc/passwd, no 'recipientdomains', or whatever. One single source of information about mailboxes. PowerMail installations will query a relational database for informationĪbout email addresses, messages are stored on disk. Incoming email can be forwarded to other email addresses. PowerMail only receives email and makes it available over POP. Sets out how the different modules cooperate. The way PowerMail works is quite unorthodox, this document PowerMail is a redundant & distributed system for receiving mail and storing ![]()
