Since Dovecot's deliver-lda does not support multiple recipient delivery, this is not a problem. LMTP can support multiple deliveries of the same message per invocation, but replies with individual SMTP codes to avoid the above problem. It can take advantage of this to efficiently implement single instance storage if it is enabled. > performance should better too Apart from multiple deliveries or SIS, I'm not sure this is true, or significant if it were.

Multiple mirrors (seems like you have plenty of offers) preferrably is multi geographical regions, using DNS round robin with TTL 0 on www and ftp , I wouldnt bother with the wiki mirroring though. However you could run 3600 seconds on it, should you need to bring it back elsewhere in a hurry.

Re: [Dovecot] Having trouble getting Dovecot to read a ~/Maildir configuration

Murray Collingwood put forth on 4/20/2011 8:29 PM: > Hi Stan > > I only have the one account on this server, everything else is relayed > elsewhere. If this is an SMTP relay server, I'm surprised you bothered to install an IMAP server at all. It would have been easier to simply alias postmaster@ to another account on another machine where you do store mailboxes. I.e. simply 'forward' all postmaster mail to you main account and use Sieve to sort all postmaster mail into a folder. This is exactly what I do. It's what a lot of people do, especially those handling many domains, and thus having lots of postmaster addresses. > A question about where the mail is actually supposed to be delivered to... > initially I configured Exim4 to delivery the email to ~/Maildir and I > noticed as you saw in the list directories like ~/Maildir/new and > ~/Maildir/cur, however once I configured Evolution to login to Dovecot I > noticed the directories ~/Maildir/INBOX/new and ~Maildir/INBOX/cur were > created. Should therefore Exim4 be configured to ~/Maildir/INBOX instead of > just ~/Maildir ? Configuration of maildir can be a little confusing the first time around. Given your situation/server, I'm really surprised you didn't use mbox instead. It fits this scenario much better than maildir. > Voila!

Setting up Dovecot LDA with EXIM: http://wiki1.dovecot.org/LDA/Exim You're probably using procmail or maildrop currently. I don't use either of these, so I'm unfamiliar with their setup WRT maildir. Should be pretty straightforward though. > RoundCube still isn't working but I'm not going to worry about that - > Evolution will be cool. Need more details to help with RC. As long as you can establish an IMAP connection to Dovecot, RC is pretty smart about figuring out where everything is even if you don't explicitly tell it. > Thanks for your help - simply confirming one setting helps. Heh, I didn't do much, but you're welcome. Are you planning on migrating all the mailboxes from the old server to this new one? -- Stan

[Dovecot] Having trouble getting Dovecot to read a ~/Maildir configuration
by Murray Collingwood 26 Apr '11

26 Apr '11

Hi folks Setting up a new server, hence a few software packages have been upgraded / changed. On my old server (only 2 years old) I was using Dovecot and RoundCube (web mail app) and had a good experience so was keen to use these again. The only major change is I have switched from sendmail to exim4 (which was installed by default on this Debian server). Exim4 appears to be doing the right thing, however read on and see if you can spot the error. I've tried two email clients, RoundCube (via apache) as a local connection and Evolution as a remote connection. Both appear to login to the Dovecot IMAP connection okay (log entries included further down), although they don't see any email. The INBOX is completely empty. Although when I check out /home/postmaster/Maildir/new it has many messages waiting to be read. It's like Exim4 is delivering the email into the ~/Maildir folder but Dovecot is not seeing it.... I've tried these three combinations in dovecot.conf but they give the same result: #mail_location = maildir:~/Maildir (ie this one I commented the line out to see if Dovecot would work it out automatically) mail_location = maildir:~/Maildir (I think this one should work) mail_location = maildir:~/Maildir:LAYOUT=fs (Now I'm just desperate and will try anything) The dovecot log gives no indication of any errors: This is the version I am running - it was the default version for Debian installed via apt-get: 2011-04-21 08:55:22 dovecot: Info: Dovecot v1.2.15 starting up (core dumps disabled) This connection is using Evolution email client on Linux: 2011-04-21 08:40:05 imap-login: Info: Login: user=<postmaster>, method=PLAIN, rip=122.148.149.28, lip=202.125.41.111 This connection is using roundcube via apache on the same server: 2011-04-21 08:40:41 imap-login: Info: Login: user=<postmaster>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured 2011-04-21 08:40:41 IMAP(postmaster): Info: Disconnected: Logged out bytes=39/443 And finally a look at the ~/Maildir content for my "postmaster" user: root@ds5683:/etc/dovecot# ls -al /home/postmaster/Maildir total 148 drwx------ 6 postmaster postmaster 4096 Apr 21 08:55 . drwxr-xr-x 3 postmaster postmaster 4096 Apr 19 08:12 .. drwx------ 2 postmaster postmaster 12288 Apr 21 08:40 cur -rw------- 1 postmaster postmaster 89088 Apr 21 08:40 dovecot.index.cache -rw------- 1 postmaster postmaster 2376 Apr 21 08:40 dovecot.index.log -rw------- 1 postmaster postmaster 5208 Apr 21 08:40 dovecot-uidlist -rw------- 1 postmaster postmaster 8 Apr 21 08:55 dovecot-uidvalidity -rw------- 1 postmaster postmaster 0 Apr 21 08:34 dovecot-uidvalidity.4daf5f73 drwx------ 5 postmaster postmaster 4096 Apr 21 08:56 INBOX drwx------ 2 postmaster postmaster 12288 Apr 21 09:39 new drwx------ 2 postmaster postmaster 4096 Apr 21 09:39 tmp So, can somebody help me get Dovecot to recognise the messages in this mailbox please?

Hi all I hope to get some help on the separator. I am sure that I hava a wrong understanding what the separator is. I thaught the separator is the delimiter within the imap folder structure. For example: Imap folder structure: folder Flights, subfolder Lufthansa If the delimiter is . the ls a command should result: .Flights .Flights.Lufthansa If delimiter is / Flights Flights/Lufthansa I tried several delimiters but only the . Works. My dovecot.conf file: mail_location = maildir:/vmail/%d/%n namespace { type = private separator = / location = maildir:/vmail/%d/%n inbox = yes subscriptions = yes } I would appreciate any help Mit freundlichem Gruß Carsten Laun-De Lellis Dipl.-Ing.
