The Site Manager limits inbox sizes for what is stored on the server to under 50M for POP accounts. This is to help ensure that the emails arrive quickly and there is no corruption.
If you are on a POP account, going above 50MB risks e-mail loss through mailbox corruption. We do not recommend setting your quota above 50MB. Please either set your mail client to remove mail from the server after 5-10 days, or upgrade your Site Manager mail server to Dovecot IMAP [requires a dedicated IP address].
Please see this link for instructions on how to install IMAP.
If a POP3 mail user is not responding and you cannot connect to it, check for a /var/spool/mail/.user.pop file.
If an email user is getting “-ERR [SYS/PERM] Unable to process From lines (envelopes), change recognition modes or check for corrupted mail drop.”
First, check the /var/spool/mail/user file, and make sure the top line looks correct, i.e. “From firstname.lastname@example.org ”. If it does perform the following:
1) cd /var/spool/mail
2) mv user user.bak
3) touch user
4) From putty, telnet domain.com 110, login with the username and password
5) cat user.bak >> user
6) telnet into the user account again, to make sure it works
7) try logging in again
When setting up or modifying a FTP user there is a check box that says "Use Exisiting Directory".
This checkbox does two things at the same time.
1) It will prevent the destination folder from being overwritten
2) It will attempt to move the user's current Home directory (if any) to the new destination
In most cases this works without any problems, but if you are changing an existing FTP user and you want to change their FTP Home directory, this may cause a conflict. It will give an error similar to the following:
A system error has occurred.
Please try again, and if it persists, contact your service provider.
This is because it was not able to transfer over the current directory to overwrite the new specified directory.
One solution is to delete the user and their home directory, then re-add the user pointing to the correct directory.
If you want to keep the files, you may need to transfer them over first.
Alternately, you could edit the file /etc/passwd and carefully change the path for that user. (I recommend backing up the file first)
