And one of my colleagues asked me for some +comments on IRC. After we have chatted for a moment, I thought it might +be nice to have these comments collected and published as my record of +the real experience with the life outside of the Cloud. + +First of all my colleague asked me about my experience with the biggest +danger of self-hosting, downtime and possible data loss. I have to +admit that this is a place where I cheat a bit. MX records for my domain +are pointed towards hosted server of my relatives’ company. Messages are +then pulled down via fetchmail (yes, I know there are better options for +fetching mail, but so far fetchmail seems to do the job right). Yes, +I don’t have UPS and only backup I do is to rsync key information to the +other computer in the home LAN (I am still ignoring TWiT ads claiming +that there must be one copy of backups off site … yes, they are right, +but I am afraid it would be quite expensive both in terms of required +bandwidth, which is not free here, and price of the service). + +The second obvious problem of self-hosting email is dealing with spam. +I use dspam_ from Fedora EPEL 6 packages, but I am actually looking for +something much more simple. Configuration of dspam is pretty tough thing +to do and apparently I haven’t done it correctly, for example the admin +inerface doesn’t work. I think it is time to switch to something more +Unixy, simple standard tools for doing simple things. In this case I am +thinking about going back to procmail and per-user bogofilter, but +I haven’t enough time and courage to do it yet. + +**Update later:** So, I’ve got rid of the dspam, and with help of +trivial (mostly out of the manpage) procmailrc and this `trivial Python +script`_ (yes, the name of the repository is wrong) I have hacked +together the three-folder system which works pretty well. + +.. _dspam: + https://admin.fedoraproject.org/pkgdb/acls/name/dspam +.. _`trivial Python script`: + https://gitlab.com/mcepl/dspam-folder-training/blob/master/train_bogofilter + +But, these are just tools around the central server, which is in my case +Zarafa_. Well, Zarafa. There is a good news and bad news about Zarafa. +The good news is that it actually really works. It serves for me as +IMAP, CalDAV, ActiveSync server, taking care of my emails, calendars, +and contacts. It works flawlessly with Thunderbird/Lightning combo (no +Contacts though), my wife’s Android phone (together with CalDAV-Sync_, +Tasks_, and ActiveSync it serves emails, calendars, contacts, and even +todo list), and for my Firefox OS (for emails and calendars with native +apps, unfortunately I haven’t found a good CardDAV support and all ToDo +apps suck, so far). That’s the good news. Bad news is that Zarafa is +AFAIK the **only** FLOSS application I know about which provides so +complete service. + +.. _Zarafa: https://community.zarafa.com/ +.. _CalDAV-Sync: + https://play.google.com/store/apps/details?id=org.dmfs.caldav.lib +.. _Tasks: + https://play.google.com/store/apps/details?id=org.dmfs.tasks + +It is not a crazy memory hog as I was afraid of C++/PHP/MySQL +application. Configuration is a bit complicated and some parts have to +be done using own scripts or third party applications (e.g., there is no +anti spam bundled, support for CardDAV is community provided and +unfinished hack, backup), but I guess some of these are better provided +in the paid-for enterprise version (I use pure FLOSS packages from EPEL +6; do you notice the pattern?). FLOSS version doesn’t allow calendar +sharing (that’s only for enterprise version, which seems to me too much +crippleware … why I cannot share my calendar with my wife?). + +Also, I have a huge problem with storing all my emails in some +proprietary database storage. Both because of proprietary (meaning, +non-standard) and database. Emails should in my opinion be stored in +mbox/Maildir/MH storage and database should be used only for indexing of +such store. + +I understand that Zarfa is a commercial enterprise and they need to make +money for their salaries (and I am grateful they provide so much +software as a free software), but it seems to me generally, their goals +and mine are a bit different. I would like the best possible +mail/calendar/contacts/task server using only open standards (BTW, +I don’t like that the only way how to access contacts is via +ActiveSync). Zarafa as a company has obviously as the biggest goal to be +cheap/open-source alternative to Microsoft Exchange and it seems to me +that people like me are just accidental beneficiaries of this other +project. + +I would love to be able to replace Zarafa with truly free and +open-standard based alternative. Dovecot would probably do as a email +server, there are some webmails, but I don’t know about **well** working +and **stable** CalDAV/CardDAV server (and Thunderbird sucks as a CardDAV +client). I may try DaviCAL one of those days, but it still seems to me +hacky and too large for solely a family server (Zimbra is completely out +of my league with its hardware and other requirements). + +Also, webmail. It is quite popular application these days, so it must be +said, that the Zarafa ones sucks. Both old one (the only one which has +been packaged for EPEL 6) and which is an attempt to create 100% +faithful bug-by-bug compatible copy of some ancient version of the +Outlook Web Access. There is also a new more Web 2.0 like version of the +webmail, but it has not been packaged in the Fedora yet (there are some +problems with some Flash files or something), so I have to use upstream +packages (which are kindly provided for all versions of RHEL, true). +Also the new version seems to be a bit slow and I cannot say I would be +keen on having it as my day-to-day client. On the other hand, it +certainly gets job done when one is outside of the real computer, which +I think is the most important role of webmail anyway. |
