I have Courier-IMAP running along with Squirrelmail Webmail and Postfix. Postfix is delivering messages just fine and Squirrelmail does not appear to have any problems. However, when I connect using a third part client such as Outlook or from my Motorola Q, I have a small problem. The email account is established as an IMAP account. The account will successfully download emails from the server and will send email as well. However, when emails are deleted from the remote account, they are not deleted from the server. I am guessing it is a permissions problem, but I don't know where to begin. All of my Postfix related stuff runs under virtual:virtual. I would appreciate any help to get me pointed in the right direction.
Deleting of mail from the server has nothing to do with postfix, postfix's responsibility ends after delivering the mail to the mail store. This seems to be a client problem, if the server is not logging a permissions error. Try connection to the server using telnet and deleting the mail and see if it actually gets deleted.
I am by no means very experienced at using telnet. However, I did connect in order to test that all the appropriate services were listening after setting up and configuring. Should I telnet into the SMTP port or the IMAP port? I know that Postfix likely has nothing to do with this issue. I am guessing it is either the client or a permissions issue with Courier. Does Courier run as a specific user? Could I add that user temporarily to the group that owns the Maildir folder to see if it is permissions related? Or which log should I look into to see if a permissions problem is being logged? I really appreciate your help. Thanks.
ISPConfig comes with some default firewall rules. The IMAP port 143 is closed by default. Please, verify if the IMAP port 143 is open and the firewall rule has been set to "Yes" instead of "No". You can do this within ISPConfig under Management > Server > Services > Firewall
I am able to connect via telnet to the mail server. I know this was the case already, but I double checked and yes, port 143 is being forwarded by the gateway to the server and the firewall is open for this port. As I mentioned before, I get mail on my mobile device through an IMAP connection, it just doesn't delete the emails. Through telnet, I connected, logged in and selected the INBOX folder. However, I have done some searches online and can't seem to find (or maybe understand) the commands to actually select and delete a message. I think this is the pivotal test to see if it is a problem with my server or with the client. Anyone have good directions for me or a tutorial online that I could follow? Thanks.
Does this help? Code: . getacl INBOX Code: * ACL "inbox" "owner" "acdilrsw" "administrators" "acdilrsw" Should there be a "d" flag returned from this command to allow for the deletion of emails? For the record, Postfix is using a MySQL backend. So the users of the email system are not users of the box itself. Thanks.
I don't believe so. However, I am not sure I am looking in the right logs. I have several mail logs, but I don't see anything in them related to errors when attempting to delete. The mail.err and mail.warn don't have any entries since last November. I see the mobile client connecting, authorizing and TX/RX data packets within the syslog log file which is normal. There are no errors reported. I believe that Courier is logging to syslog, but maybe I am mistaken. Does this help at all? Otherwise, tell me where else I should be looking for clues.
Falko, I did set up a second server this weekend strictly following your How To for the Perfect Server with Ubuntu 7.10. The server that is giving me problems with the IMAP functionality was setup using a How To by Flurdy (easy Google search by Flurdy email). Although this second machine was supposed to be much more of a test server, I suppose I could change my network to have it be the active mail server and see if the IMAP problem still persists. Maybe this would help define whether it is my client or server. Lastly, I did install ISPConfig on the second server. It took a while, but the machine is older too. I have read through the a lot of the docuementation for ISPConfig. But are there are tutorials or examples on how you would actually use the software (i.e. A walk through on adding customers, hosting plans, invoicing, etc.)? Thanks.
Update So here is the update after a complete rebuild last weekend. I used the Falko guide to for the Perfect Server Ubuntu 7.10 setup. I did not do any of the items that were ISPConfig specific (I am still debating whether to install this program). I then used the Falko Guide on Virtual Hosting with a MySQL backend for Ubuntu 7.10 to setup Postfix. (http://www.howtoforge.com/virtual-users-and-domains-with-postfix-ubuntu-7.10) Regarding my Windows Mobile Client, I am still unable to delete emails from my IMAP server. However, I found some posts that seem to point to Windows Mobile 5 OS as the culprit. I had a friend with a Windows Mobile 6 device connect and test the procedure and the email was deleted. So I think I have indentified the problem, but don't have a work around yet. However, I do have a new problem. I cannot send emails from my mobile device. My server bounces them. This is a line from the logs: Code: Apr 20 16:27:16 gopher postfix/smtpd[6471]: NOQUEUE: reject: RCPT from 99-200-132-141.area2.spcsdns.net[99.200.132.141]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<Inbox> mydomain1.com is a virtual domain hosted on my server. I can connect and receive emails on my client just fine with this account. Thanks.
I looked back at my old main.cf file for Postfix before rebuilding the server using the Falko guide. I had the following section in my old configuration file. Code: # Requirements for the sender details smtpd_sender_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_non_fqdn_sender, reject_unknown_sender_domain, reject_unauth_pipelining, permit I don't have an smtpd_sender_restrictions section in my new configuration file as it wasn't part of the How To. Should I add the old section back in? What is the harm of doing so? Do you think it would solve my issue? I have also been tailing my mail log when the client is connecting and attempting to send mail. This is what it shows: Code: Apr 27 00:26:51 gopher pop3d-ssl: LOGIN, [email protected], ip=[::ffff:99.203.32.237] Apr 27 00:26:54 gopher postfix/smtpd[7003]: connect from 99-203-32-237.area2.spcsdns.net[99.203.32.237] Apr 27 00:26:54 gopher postfix/smtpd[7003]: setting up TLS connection from 99-203-32-237.area2.spcsdns.net[99.203.32.237] Apr 27 00:26:55 gopher postfix/smtpd[7003]: TLS connection established from 99-203-32-237.area2.spcsdns.net[99.203.32.237]: SSLv3 with cipher RC4-MD5 (128/128 bits) Apr 27 00:26:57 gopher postfix/smtpd[7003]: warning: 99-203-32-237.area2.spcsdns.net[99.203.32.237]: SASL LOGIN authentication failed: authentication failure Apr 27 00:26:59 gopher postfix/smtpd[7003]: warning: 99-203-32-237.area2.spcsdns.net[99.203.32.237]: SASL LOGIN authentication failed: authentication failure Apr 27 00:26:59 gopher postfix/smtpd[7003]: disconnect from 99-203-32-237.area2.spcsdns.net[99.203.32.237] Apr 27 00:27:00 gopher pop3d-ssl: LOGOUT, [email protected], ip=[::ffff:99.203.32.237], top=0, retr=0, rcvd=18, sent=89, time=9 Thanks.
The virtual user setup is incompatible with ISPConfig, so you can't install ISPConfig... Please enable "Server requires authentication" in your email client.
I know about the ISPConfig limitations with my current setup. I am going to setup nother server with ISPConfig to evaluate it. The lack of user documentation scares m a little bit. I have placed a check next to the Outgoing server requires authentication. The error mssage I posted earlier is what is logged with the authentication option enabled. There are additional server settings for the outgoing server, but I haven't set them. Any other suggestions?
I have been looking through the Internet today for possible solutions. I have come across a couple of sites that suggest setting the following variables. Code: sudo postconf -e 'smtpd_sasl_type = dovecot' sudo postconf -e 'smtpd_sasl_path = private/auth-client' Now I know the example above is Dovecot specific, but is there anything similar that I need for my Courier setup? Also, I noticed in my postfix main.cf file that the following variable is undefined. Code: smtpd_sasl_local_domaing = Should it be undefined? Thanks.
What's in /etc/postfix/main.cf? Is the domain listed in /etc/postfix/local-host-names? Is the email address listed in /etc/postfix/virtusertable?
