Dovecot/Rainloop 2.0.13-1_129.el5
I configured Dovecot on our mail server under Centos 5.3 (I think) some while ago now (about 2 years) and, to the best of my knowledge,it had been working correctly all that time. However, one of the team wanted to use webmail while away from base and found that, although he could receive emails OK, he was unable to reply or send fresh emails. When he pressed Send he got a message “Authentication failed" in a pop-up box. He assured me that sending mail had been working and I was certain that I had tested that aspect when I was setting Dovecot up, at least for local mail. I tried to send email from my Dovecot account and had the same problem. Our MTA is sendmail and that is not configured to authenticate on outgoing mail, The configuration for sendmail hasn’t changed at least since the last update in 16 March 2015 (sendmail 8.13.8-10.el5_11). Dovecot uses php-5.5.5 in this set up. The relevant entry in /var/log/maillog when I attempt to send an email from Dovecot is: May 5 16:34:29 firewall dovecot: auth: Debug: auth client connected (pid=13001) May 5 16:34:29 firewall dovecot: auth: Debug: client in: AUTH 1 PLAIN service=imapsecured lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=51861 resp=AGNocmlzADB1dFkwdUcwNDkh May 5 16:34:29 firewall dovecot: auth: Debug: pam(chris,127.0.0.1): lookup service=dovecot May 5 16:34:29 firewall dovecot: auth: Debug: pam(chris,127.0.0.1): #1/1 style=1 msg=Password: May 5 16:34:29 firewall dovecot: auth: Debug: client out: OK 1 user=chris May 5 16:34:29 firewall dovecot: auth: Debug: master in: REQUEST 2607546369 13001 1 0bcf2e3a108cd9cd18eaff4b7de9c428 May 5 16:34:29 firewall dovecot: auth: Debug: passwd(chris,127.0.0.1): lookup May 5 16:34:29 firewall dovecot: auth: Debug: master out: USER 2607546369 chris system_groups_user=chrisuid=514 gid=100 home=/home/chris May 5 16:34:29 firewall dovecot: imap-login: Login: user=, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=13002, secured May 5 16:34:29 firewall dovecot: imap(chris): Disconnected: Logged out bytes=11/334 May 5 16:34:29 firewall sendmail[13003]: u45FYTtd013003: localhost.localdomain [127.0.0.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA The webmail server and our mail server are the same system. The firewall is open for port 143. It is only send from Dovecot that fails authentication, all other outgoing mail is sent correctly. Does anyone have any idea where else I can look for clues as to why there is this behaviour? Suplementary question: what does the “Sign me” check box on the webmail log in page do? Many thanks. Chris
[Dovecot] Dovecot does not update acl_shared_dict file
Hi all, Firstly, thanks for all your effort with this software. Much appreciated. I am having a slight issues trying to enable reading of other users mailboxes. The docs are a little sparse for those that aren't mailadmin heros, I wonder if anyone could please help me see where I am going wrong. I would like to allow some users to list and read the mailboxes of others. E.g: When User1 logs in, they are presented with a list of their own folders, and those of User2, User3, etc to which they have (e.g. read/list) access I followed the instructions on the wiki (for Version 1.X)- there are two concepts here: 1. Grant some [e.g. list/read] access on a mailbox folder to a particular user 2. Enable the acl_shared_dict to allow dovecot to track (and display to IMAP clients) the folders to which they have access. This will take the form of a BDB file: /var/lib/dovecot/shared-mailboxes.db This file can only be updated by using the SETACL command. *This is where I have the problem*. The SETACL command does nothing. No matter how hard I try, I cannot get dovecot to update this file. The only indication I have that the file exists and is readable by dovecot is the disappearance from the logs of the line: No acl_shared_dict setting - shared mailbox listing is disabled So I can see that dovecot knows the file is there because it does not complain any more. The file is there (because I created it myself, although it is empty: size = 0), and in a moment of weakness I made sure it could be updated (this will be changed back!): ls -l /var/lib/dovecot/shared-mailboxes.db -rwxrwxrwx 1 dovecot dovecot 0 2012-10-30 12:27 /var/lib/dovecot/shared-mailboxes.db But if I try to update the ACL, absolutely nothing happens: [ > command ] [ < reply ] telnet localhost 143 < * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=CRAM-MD5] Email server a login [User2] [pass] < a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH ACL RIGHTS=texk] Logged in a SETACL Inbox [User 1] rl < a OK Setacl complete. At this time, in the dovecot log (with debug enabled): 2012-10-30 13:55:24 IMAP([User2]): Info: Namespace : Using permissions from /home/mailboxes/[domain]/[User1]: mode=0770 gid=-1 2012-10-30 13:55:24 IMAP([User2]): Info: acl vfile: reading file /home/mailboxes/[domain]/[User1]/dovecot-acl 2012-10-30 13:55:24 IMAP([User2]): Info: acl vfile: reading file /home/mailboxes/[domain]/[USer1]/dovecot-acl Can anyone please help me track down what I'm doing wrong here?!
