I use [Froxlor] on a debian 10 server only to manage my customers email accounts. Installed is Courier 5.0.6 and postfix 3.4.23. I plan this to first upgrade to Debian 11 then migrate to dovecot. How do I proceed?

I use Courier with postfix on debian 11 and it all works fine, except, I cannot copy large emails into the IMAP Sent Folder. I cannot find the richt configuration files and options, where I set the maximum email-size for Courier IMAP

I run Courier IMAP with STARTTLS support. Currently, IMAP_TLS_REQUIRED is set to 0 (false), meaning that a client is fully permitted to use a clear-text login on an unsecured channel. Setting it to 1 (true) is not an option, as it breaks SquirrelMail (which can't use STARTTLS); however, I know for a fact that only certain IP addresses are legitimately going to be using unencrypted transport. In the simplest case, it should theoretically be possible to permit connections from 127.0.0.1 without encryption, while demanding STARTTLS before auth on all other connections. However, I've been unable to do this. Also, what if I want something more complicated - maybe there's a web server on 203.0.113.147 talking to an IMAP server on 203.0.113.148, with a secure LAN in between. (Ignore for now the challenge of proving that the LAN truly is secure.) Is there a way to set IMAP_TLS_REQUIRED differently for different connections?

I swear that courier-mta was working before, but now it has stopped working. The problem first started out with getting "submit: Permission denied" errors and I was unable to send emails to the machine. I chmod'd /var/lib/courier/tmp (via chmod 771 /var/lib/courier/tmp) which fixed this. But, now all the messages are stuck in /var/lib/courier/tmp/NNNNNN and never get migrated to $HOME/Maildir . I cannot figure out what moves the files from /var/lib/courier/tmp to $HOME/Maildir so that I can use courier-pop. What does the moving? Note that my /etc/courier/courierd has DEFAULTDELIVERY=./Maildir in it. Thanks.

on my server is installed Courier Mail Server. It happens that one imapd process uses tons of the system resources blocking the entire server. I would like to track down the user (i.e. the mail address in Courier Mail) that is running that process. Please note: not the linux user, but the mail address. Is it possibile to infer the email address of a process given the PID of a imapd command process? Thank you,

I want to ionice a process on its startup. In our hosting environment, we use old Paralells Confixx servers. (Yes I know, Confixx is outdated, but that is not the question). We use courier for mails and sometimes it happens, that the /usr/bin/imap Maildir process eats up the whole I/O which also causes high CPU load. We allways manually ioniced (ionice –c 3 –p [PID] ) the process and the I/O went down. What is the best way to automatically ionice every imap process? I’m not very experienced in the courier mail server.

I have been investigating this for a long time but I'm not able to find a solution: I have an up&running mail server with Postfix and Courier in an Ubuntu Server. I'm using PAM users with a Maildir mailboxes structure. All this is working in the same hard disk. The problem is that I need to install/configure users mailboxes in a bigger disk unit already configured in my server ("sda" is where ALL is installed and "sdb" is where I want to setup the users mailboxes). Is not needed to migrate actual mailboxes. I,m not able to say to Courier to "look" at the users Maildir in the "sdb" drive when the mail client check the mailbox. Any help will be very appreciated. Thank you all!.

Picture a mail store for virtual users. Arriving mail is managed by Postfix (creating new files); access to mail is provided by Courier IMAP (moving files around, deleting files, creating sent mail); and periodically, off-site backups are taken (reading files without changing anything). Obviously this will all work if every process runs as root; equally obviously, they shouldn't all run as root. The current setup has all the files owned by the postfix user and group. The Postfix and Courier processes all run as that uid/gid. But I would like to have the backup process run as a dedicated read-only user. Is there a way to tell Postfix and Courier to create their files as user backup:postfix with permissions 0464/0575? I'm on Debian GNU/Linux if that makes any difference.

My mailserver delivers mails successfull in Maildir format. But I cannot connect to courier through IMAP. It refuses the connection. The firewall port 143 is opened.

I just installed an E-Mailserver using exim for SMTP, courier(-imap) for fetching mails via IMAPv4 and squirrelmail as web client for the end user. Everything works fine. But when I sent an E-Mail to adress on my server, it is stored in the file /var/mail/, but not in the maildirs I created in /home//Maildir I am also able to log into squirrelmail. Sending mails also works. The copy of the sent E-Mail is stored in the right directoy. So, how do I tell exim to deliver incoming E-Mails to /home//Maildir/INBOX?

I'm having difficulty with maildir permissions for **Courier** , an IMAP server I've installed on a box running Debian Wheezy. The mail directory I use is /var/mail/users, with the following permissions: drwxr-sr-x 3 mail mail 4.0K Oct 14 08:09 users This directory has chmod 750 permissions. The individual *user* directories inside /var/mail/users have the following permissions: drwx------ 6 johnsmith johnsmith 4.0K Oct 14 08:13 johnsmith Note that the individual user directories are owned by the user, and have permissions of 700. The problem is that this causes courier to fail when it tries to access the user directories. (The error message courier gives is vague, but I'm certain it's a permissions issue): # telnet localhost 143 Trying ::1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION STARTTLS] Courier-IMAP ready.

Courier doesn't say why and there's nothing in /var/log/mail.log, but I'm 99% sure it's a permissions issue, because if I change the permissions on /var/mail/users/johnsmith to 777, courier has no problem with the STATUS command and reports success. But of course, I don't want to set permissions to 777. I thought perhaps the problem is that the /var/mail/users/johnsmith directory should be owned by mail instead of johnsmith. So I tried doing that, but then courier fails on the LOGIN command: 0 LOGIN johnsmith@myhost.com mypassword * BYE [ALERT] Fatal error: Account's mailbox directory is not owned by the correct uid or gid: So what are the safest correct permissions I should set for the maildir (and maildir sub directories) so that courier can successfully login and access each dir?

I've successfully installed sendmail, but when I connect to the Courier IMAP server via Outlook, the Inbox is listed as empty. When I check the inbox with Alpine locally on the server, it has content though. Why? I do see files with content in /var/mail . Is that not where Courier-imap checks for mail? The setup is pretty clean - I run Ubuntu 12.04 on AWS, have installed sendmail and courier-imap. sendmail was configured with sendmailconfigure and it works well to both send and receive mail. The problem is with courier.

I'm running into a weird issue setting up Postfix and Courier IMAP on a clean Ubuntu 13.04 install. I'm using this tutorial , and am currently Testing Courier IMAP . When I try to login with root, everything's fine (this is part of a netcat connection): a login root my-pass a OK LOGIN Ok. a logout * BYE Courier-IMAP server shutting down a OK LOGOUT completed However, when I try to login with my own account, I get an error: a login camilstaps my-other-pass * BYE [ALERT] Fatal error: No such file or directory: No such file or directory The mail.log: Jun 2 13:47:37 cs imapd: Connection, ip=[::ffff:127.0.0.1] # this is the root login Jun 2 13:47:51 cs imapd: LOGIN, user=root, ip=[::ffff:127.0.0.1], port=, protocol=IMAP Jun 2 13:48:11 cs imapd: LOGOUT, user=root, ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=9, sent=80, time=20 Jun 2 13:50:59 cs imapd: Connection, ip=[::ffff:127.0.0.1] # this is the other login Jun 2 13:51:07 cs imapd: chdir Maildir: No such file or directory Jun 2 13:51:07 cs imapd: camilstaps: No such file or directory And the mail.err, not really adding something: Jun 2 13:51:07 cs imapd: camilstaps: No such file or directory I configured Postfix to use the Maildir format using /var/mail/%u where %u is the username. At first, I thought the camilstaps user missed his mail folder. However, it does have one similar to root's one: root@cs:/# tree -CdA /var/mail /var/mail ├── camilstaps │ └── Maildir │ ├── cur │ ├── new │ └── tmp └── root └── Maildir ├── cur ├── new └── tmp Then I thought the camilstaps user had a different maildir in the MAIL constant, however... root@cs:/# echo $MAIL /var/mail/root camilstaps@cs:/$ echo $MAIL /var/mail/camilstaps What's going on here? How can I fix this? For what it's worth, I'm on Ubuntu Server 13.04. --- With help from the comments, I found out something interesting / possibly useful: * There was an old Maildir in /root. When I remove that one, I get the same error when logging in as root to the IMAP server. * When I add a Maildir directory to the homedir of the camilstaps user, I don't get the error anymore. For some reason, the IMAP server doesn't look in /var/mail/%u (%u = username) but in %h/Maildir (%h = homedir). The $MAIL variable has been set correctly, so what could be the problem here?
