[SM-USERS] Error: Connection dropped by IMAP server with dovecot
Hi there -- I am running SquirrelMail version 1.4.8-5.el5.centos.10 on a CentOS 5.6 64-bit distribution with MailScanner 4.83.4, Sendmail 8.13.8/8.13.8, and Dovecot 1.0.7 release. All applications listed, with the exception of MailScanner, are the packaged versions that come bundled with the operation system. The server is a rebuilt and updated version of an older Fedore Core 7 32-bit mail server. During the rebuilding process all /var/spool/mail folders, as well as all user home directories, were restored from disk backup. This included rebuilding the /etc/passwd and /etc/group files, as well as verifying that ownership and permissions for the users' files were kept intact. One user is having problems connecting via the SquirrelMail interface to his e-mail. Whenever he tries to connect, he gets the following error message: Error: Connection dropped by IMAP server with dovecot I have tested another user account via the SquirrelMail interface, and that user is able to connect without issue. I confirmed the presence of dovecot.index, dovecot.index.cache, and dovecot.index.log files in the problem user's /mail/.imap/INBOX folder. The /var/log/maillog files do not list any apparent error messages with SquirrelMail. Does anyone have any idea as to what other steps I need to take to correct this issue? Thanks.

In the dovecot.conf there is a line to limit the UIDs that can connect as it's just one user maybe it's something to do with that ? mick -- Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.

Re: [SM-USERS] Error: Connection dropped by IMAP server with dovecot
Check the permissions for the users folder. /mail/.imap/INBOX Make sure the mail server/user has write access to these files. Check dovecot.conf to make sure there are no block lists that stop this user connecting. Are both users using the same domain name for their email address?

Re: [SM-USERS] Error: Connection dropped by IMAP server with dovecot
Hi there -- Thanks for your reply. I did some investigating of the dovecot.conf file, and I came across something in addition to your suggestion. The section I am referring to is shown below: # Valid UID range for users, defaults to 500 and above. This is mostly # to make sure that users can't log in as daemons or other system users. # Note that denying root logins is hardcoded to dovecot binary and can't # be done even if first_valid_uid is set to 0. #first_valid_uid = 500 #last_valid_uid = 0 I ran the cat command on the passwd file, and did a grep for the two user accounts. The account that worked had a userid that was greater than 500, while the one that did not work had a value below the 500 integer. I changed the uid of the problem user account to a value greater than 500, and was subsequently able to log into the server. Thanks for the help. > In the dovecot.conf there is a line to limit the UIDs that can connect as > it's just one user maybe it's something to do with that ? > mick The information in this e-mail is intended only for the person to whom it is addressed.
