[Dovecot] Wiki: virutal user with Sendmail and OpenLDAP
by Zoong Pham 20 Apr '04

20 Apr '04

In the Wiki, section 2, "Virtual user support with OpenLDAP", does the example apply to non Sendmail? If that's the case, can someone post a quick guide about setup virtual user with Sendmail. I use OpenBSD-3.4, BTW. TIA, Zoong

[Dovecot] Can't resolve address 127.0.0.1
by Alban Dani 19 Apr '04

Hi , I recently installed Fedora Core 1. Installed postfix on it and that is running fine. I am trying to get dovecot to run and I have changed only the following line from the default dovecot.conf : imap_listen = 127.0.0.1 since I'd like to install squirrelmail later on. Now when I try to start dovecot I get "Starting Dovecot Imap: Fatal: Can't resolve address 127.0.0.1 : Name or service not known" Can anybody help me? Alban

[Dovecot] adding new user to dovecot

Hi, Your mail was very insightful. You have stated in you mail as follows .. "But I think they create virtual users in database systems for email, I can't imagine all of the users they have are in one passwd file on one tiny machine." a. What do you mean by virtual users. b. How does one link them to a mailbox. Very frankly i am confused... 1.Well lets say i have a user who wants to create a new group say GROUP1.Lets say i have users who want to create GROUP1(a)pigeonhole.com or GROUP2(a)pigeonhole.com .This group name will be entered in my JSP page, now what do i have to do to create the group. 2.How do i see to that anyone who sends a mail to GROUP2@pigeonhole receives it in it mailbox( Firstly does the group have a mails box in the groups name).Will one create a account(mailbox) for the group or how is it done. 3.Lastly I actually want to create a mailing List manager. Please advice on how to go about it.

Hi, Thanks a lot for the mails.Well one major doubt that was prevailing was that do i need to create a system account for each person in order to send/receive mails, and from both(Sven Kirmess & Johannes Berg ) your mails i gather it is a must. But Is there a workaround to this? I have actually configured dovecot because i required a mail server in order to build a mailing list manager.A mail list manager is something in the likes of yahoogroups, where each group in my case must have a mailbox. 1. I am using Debian OS. The software that i am creating , which is going developed in JSP, will take a new users name and password and create a account for him by executing a shell script in my linux machine.I assume yahoo also does something similar to this to create new mail boxes for any new user.Please correct me if i am wrong. In fact this very mail that i have received from you is because i have subscribed to the dovecott mailing list. How do you think dovecott has been able to accomplish this. Is it not because that dovecott has a mailbox in the group name "dovecott" in some system, that internally does the sending of mails to all those in the groups refering to some database. 2.Will the mail server support me in anyway by giving me some functionality to add users, thereby creating maildir's (imap) for the users. 3.Dont I need to know the admin login and passwd, to create users? 3.Lastly i know this is not that prevalent a question -> I was told mail man does a similar job as to what my software will do.Do you know how mailman works (or even yahoogroups)?. Please enlighten me on the above issues. Thanks a lot for you time. Regards Kartik

[Dovecot] adding new user to dovecot

Hi, This is from your documentation Creating new users ------------------ Dovecot is interested in only one thing - being able to find the user's mail directory. With maildir you need to do mkdir ~user/Maildir, with mbox mkdir ~user/mail. what does ~ refer to. Pardon my ignorance in unix, i am relatively new to unix. Does not ~ refer to the user account in which you have logged in. So does that mean that maildir folder exist for only user accounts that already exist.My intention for asking the above is that i have a java program running, that will take a new users name and password, so with that can i create a mailbox for that person , or does the admin have to create an user account for that person , so that his maildir folder can be created. Please clarify my understanding of how it workds.. Thanks

If anyone knows someone with CVS access can they please take another look at http://bugs.gentoo.org/show_bug.cgi?id=22080. It has been in bugzilla for nearly nine months. Would like to see this in portage - masked is fine - so at least everyone is working off the same file. Cheers Zach.

Is that dovecot in your FAQ serving mbox or mdir format? Thanks, Zoong -----Original Message----- From: Avery Day [mailto:schrock@dayzed.com] Sent: Tuesday, 13 April 2004 12:07 PM To: dovecot(a)dovecot.org Subject: [Dovecot] I added a "SQ and Dovecot FAQ" on the SQ website On the Squirrelmail website I setup in the FAQ a quick install guid on how to get squirrelmail to work with Dovecot. Maybe someone can verify my setup procedure really quick. Maybe someone thinks this is wrong. Also if you have something to add please do so. No one has bothered to do this before so I took it upon my self.
