[Dovecot] How to see folders/subfolders/emails through imap
by Stephan von Krawczynski 10 Apr '13

10 Apr '13

Hello all, I am trying to do something very simple - at least thats what I thought. I have some fs, it contains folders and subfolders with email files ordered like maildir. Now I try to set up dovecot on top simply to let some imap account watch these email files. But I cannot see any folders at all. I can create new folders and see them, but I cannot create subfolders as subdirs like "folder/subfolder". Instead I get "folder.subfolder" dirs on the fs. I tried to set the separator to "/", but that does not help at all. Is there some easy way to configure dovecot to display: <somedir>/<folder1>/<subfolder1>/new/files... <subfolder2>/new/files... <subfolder3>/new/files... according to fs layout on some imap-client (like thunderbird)? -- Regards, Stephan

You probably want to compile in tcp_wrapper support and handle it that way http://wiki2.dovecot.org/LoginProcess You might also hook into a the post-login script if you need some bizarre logic to determine whether to allow a login or not, but this is later in the session setup rather than block-on-sight like a firewall. http://wiki2.dovecot.org/PostLoginScripting Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] How to exec /usr/libexec/dovecot/imap with specific maildir location
by David Woodhouse 09 Apr '13

09 Apr '13

Once upon a time I could configure my mailer to access my historical archives by running something like ssh $mailserver MAIL=maildir:~/Maildir-archive dovecot --exec-mail imap I need to run /usr/libexec/dovecot/imap manually now, and I've fixed that a while ago for my normal email access. But I've just had cause to go back to my archives for the first time in a while... and realised that I don't know how to make it work any more. When invoking /usr/libexec/dovecot/imap, is there an environment variable or command line option which can set the mail location? -- dwmw2

[Dovecot] Any simple way to block logins by IP address?
by Steve Campbell 09 Apr '13

09 Apr '13

Does Dovecot have a facility to block pop3 and imap logins by IP address. I usually do this by putting the IPs in my border firewall, but it's in transition currently to a new one, and I'd like to end connection fairly fast. If it matters, I'm using 2.0.9. Thanks steve campbell

[Dovecot] Received date on emails is wrong after file copying
by maia＠weiser.dk 09 Apr '13

09 Apr '13

Hi, I have installed a new mail server where I'm migrating from Courier to Dovecot. I have made a mistake when I was copying over the emails so the date/time mark on them is updated. So all my mails are now from the copy date/time and not the real receive time. I have tried to copy the emails over again, so they get the right date/time on the file level. And when I look at a single email in details in SquirrelMail it has now the right date/time, but when I look at the overview of a folder it still have the copy date/time on them. Is there any way to get the date/time in the overview updated, maybe delete some index files or force it to re-index? I'm not even sure that the problem is in Dovecot. But I'm sure You can help me here. Best Regards, Kim Johansen

[Dovecot] script to detect dictionary attacks
by Reindl Harald 09 Apr '13

09 Apr '13

Hi has someone a script which can filter out dictionary attacks from /var/log/maillog and notify about the source-IPs? i know about fail2ban and so on, but i would like to have a mail with the IP address for two reasons and avoid fail2ban at all because it does not match in the way we maintain firewalls * add the IP to a distributed "iptables-block.sh" and distribute it to any server with a comment and timestamp * write a abuse-mail to the ISP

Hi, I've some troubles setting up the dict based quota plugin for mdbox, it always returns a error when lmtp tries to deliver an e-mail: Apr 8 12:40:16 mb07 dovecot: lmtp(3001, asmarre(a)ull.es) Error: fstat(/sharedfs/10.4.1.107/ull.es/54/asmarre/dovecot-quota.lock) failed: No such file or directory Apr 8 12:40:16 mb07 dovecot: lmtp(3001, asmarre(a)ull.es) Error: file dict commit: file_dotlock_open(/sharedfs/ 10.4.1.107/ull.es/54/asmarre/dovecot-quota) failed: No such file or directory Apr 8 12:40:16 mb07 dovecot: lmtp(3001, asmarre(a)ull.es) Error: dict quota: Quota update failed, it's now desynced In fact lmtp does create the dovecot-quota.lock file but it does not update the dovecot-quota file.
