- Q: I cannot send big attachments with SkyrixGreen. Why? The attempt to send an e-mail with an attachment of a
certain size (e.g. bigger than 1MB) fails. However, it works perfectly with an external e-mail client (Outlook,
Netscape Messenger, ...).
A: Maybe you use a proxy server with a restricted maximum upload size. Please configure your browser in such a way
that enables access to the eMail Server without a proxy server.
- Q: I cannot send any e-mail attachments using SkyrixGreen. Why? The selected attachment is displayed before
sending the message, but the recipient does not receive the attachment.
A: You have probably forgotten to click on Add Attachments
after having selected a file.
- Q: Sometimes I get the message
unable to change limit of file descriptors available
in /var/log/messages
. What should I do?
A: Ignore this message. It simply says that the cyrus-imapd process tries to increase the number of possible file descriptors.
However, the process does not have the necessary permissions because it does not run as root
.
- Q: The web server is configured for secure https connections with certificate. I have imported my client certificate
from the homepage. Why do I receive messages about a missing certificate during the connection setup?
A: The link to the homepage (SuSE Linux eMail Server CA
) is the CA's certificate and not the client certificate.
A client certificate can be obtained through your configuration frontend, provided that the system administrator has
created one for you.
- Q: I am sometimes denied access to the web server after having successfully logged in as usual. Why?
Apparently I do not have the adequate permissions.
A: You probably use a proxy server to address the eMail Server. A possible cause is that the proxy may contact
the web server with different IP addresses. In this case, the connection will be denied by web server due to security
reasons. This can be avoided by configuring your browser for direct access without proxy server.
- Q: How can relaying be allowed? Everytime I try to send an e-mail, I obtain the message 'Relay access denied'!
A: There are different possibilities:
- You use 'pop before smtp'. This is described in the article: "Setting Up POP Before SMTP" (http://sdb.suse.de/en/sdb/html/rsimai_imap_dracd.html)
- You enable 'SASL'. You can solve this as user cyrus via the webfrontend. Your mail client must support it and be configured accordingly.
- You use the parameter
mynetworks
in /etc/postfix/main.cf
.
Attention: this is advisable for experts only.
If the configuration is wrong, you will create a open relay!
- Q: Why is the configuration menu displayed everytime I press RETURN after having logged in?
A: Press the TAB key twice and then RETURN to call SkyrixGreen directly. This procedure works with numerous browsers.
- Q: I want to make a backup of the e-mail server data. Which directories and files are important?
A: A list of important files can be found in the following article: "Important Files and Directories in eMail Server 3" (http://sdb.suse.de/en/sdb/html/rsimai_imap3_files.html)
- Q: In the patch support data base there are different entries for the same package. Which one should I install?
A: Install the 'most recent package'. In this way you are always on the cutting edge.
