My suggestion would be to use Dovecot as your POP and IMAP server. And convert everything to use Maildir unless there is some special reason you want to keep mbox format for. Setup procmail to deliver all mail to the maildir folders. See my previous message on how to do it. John -- A: Because it messes up the order in which people normally read text.

[Dovecot] Loggin error with Squirrelmail on Fedore Core 2
by Antonio Nunes 03 Jun '04

03 Jun '04

Hi! I am switching a mail server setup to a new machine which has RHL Fedore Core 2 installed, which uses Dovecot. I managed to get Squirrelmail to work on my personal account, but when logging in with some other accounts I get the following error as response: ERROR : Connection dropped by imap-server. Query: Capability I did a web search on this and found a message from Tim Middleton who experienced the same problem. He also suggests a workaround: "I put in a chron job to touch into existance any non-existing mailboxes for everyone in the passwd file periodically, which mostly eliminates the problem. But I'd still like to know why the server is having the problem, if anyone can make any suggestions." I would like to try this, but I am still fairly new to Unix. Could anyone show me how to set up such a chron job? Are there other, manual, ways to touch the mailboxes? Thanks, Antonio Nunes Don't let who you can be keep you from being who you already are.

[Dovecot] Supporting POP & IMAP with Sendmail
by John Duino 03 Jun '04

03 Jun '04

Greetings! I dug thru the archives but didn't see a clear answer to this. A client has an existing sendmail/pop3 system, and I would like to switch to dovecot for imap support. For imap I much prefer the Maildir format over mbox, however, sendmail natively dumps to mbox (mailspool) and that is what pop typically reads. I've read the threads on how to make sendmail write to Maildir. My problem is that I'd like to support both pop/mailspool and imap/maildir. While running dovecot in imap-only it will use mbox format to read the /var/mail/user as the Inbox and then create the full imap structure under ~user/mail but in mbox format, not maildir. If/when I turn on both pop and imap in dovecot will it allow this with the current config? Or will I still need to convert sendmail output to maildir...and then I assume dovecot/pop will read from ~user/Maildir/Inbox even though it is in Maildir format? Basically, if I'd prefer to not have to convert sendmail to Maildir format, have dovecot always treat /var/mail/user as the Inbox for both pop and imap, and for those who switch to imap, have it store their other folders in ~user/Maildir. Asking too much? Thanks! John

Fairly easy on the small system I had. I only have around 8 people using email off of my system. > Can I keep my Inbox /var/spool/mail/user_name as an mbox > format and have > my other folders as Maildir? Timo says that it is NOT available in the version that comes with Fedora Core 2. It will be available in the 1.0 series by defining multiple namespaces. The current 1.0-tests allow this. > What would I have to change for Sendmail to make it use > Maildir for the Inbox? Sendmail does NOT need to be changed. > Can procmail support Maildir? Yes and that is what you need to change. I setup /etc/procmailrc to have the line: DEFAULT=$HOME/Maildir/ Make sure there is the terminating / on that line. What this will do is make all new mail that is delivered via procmail go to each user's Maildir folder. But what you need to do first is convert your existing mbox mail into maildir format. I used the program that was recommended to me: mb2md http://batleth.sapienti-sat.org/projects/mb2md/ This program worked great to convert my /var/spool/mail/user_name stuff and also folders that I had created under ~/mail/ So now my whole system is using Maildir format. If you had a big system this might be a big pain :( John -- A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing?

[Dovecot] Lost messages when "Moved to Trash"
by Fred Mulharin 03 Jun '04

03 Jun '04

We are using Dovecot 0.99.10.5 on a Redhat 9.0 Box. We are using the Squirrelmail Webmail client, and have occasionally had a problem with users move messages from their Inbox to the "Trash" folder. The Selected messages move to the Trash folder, but the rest of the messages in the INBOX disappear.

[Dovecot] dovecot and virtual hosting
by Vegard Svanberg 03 Jun '04

03 Jun '04

Hi. A usual hosting provider setup depends on having one IP ("virtual mailserver") per domain. Using dovecot on servers handling hundreds or thousands of domains today equals to having multiple instances of dovecot running. This problem could be solved by making dovecot take into account the IP address the user connects to and authenticate against the proper {database, table, pw-file, [...]} based on that. Comments? -- Vegard Svanberg <vegard(a)svanberg.no> [*Takapa@IRC (EFnet)]
