Email issues

[jopa123]

Hey guys,

Again. Thanks for a great product and great help. I know it is all voluntary and it is much appreciated.

My server is really not a money maker but I have put in some long hours on making the 15 or so sites on it work. It's more of a learning experience for me.

My setup is Ubuntu 9.04 and ISPConfig 3 per - http://www.howtoforge.com/perfect-se...04-ispconfig-3

I recently found that I was having email issues. I can't receive any emails to any of the domains that I have setup on my server. I did some research and it seems that this is a semi-common issue. I've searched through my logs to see if I can isolate the issue but don't see anything that stands out to me and most fixes i find either do not apply to my distro or I'm not comfortable trying them. My Linux skills are very limited.

Any advice or help? Also, should I backup and reinstall a newer distro as this one is quite old?

Any and all help is greatly appreciated.

Thanks.

I don't think I can update/upgrade ClamAV with this distro.

I don't think I can update/upgrade ClamAV with this distro.

This is not the reason for your issue. It does not matter if clamav reports that it is outdated as long as freshclam downloads new updates.

Regarding your original issue, please post the exact error messages from your mail.log file.

Thanks, Till

I don't see any error messages in mail.log but 'postqueue -p' does show this type of thing:

Run:

ls -la /var/vmail

it should show you a list of directories that have the same names then your email domains. If you see the folders exist, run this command to recursively fix all permissions:

chown -R vmail:vmail /var/vmail

[jopa123]

I ran the command and senta test email and this line was added to 'postqeue -p'

Check the permissions for maildrop. It needs to be setuid root. chmod +s /usr/bin/maildrop.

Thanks, Florian030 but that didn't seem to work either.

I'm beginning to think it may be an issue with my internet provider or my DNS zone files at the registrar

As always, any help is appreciated.

Did you check the permissions of the mailbox and all directories in the path to the mailbox?

Falko,

I'm not sure what you mean by "the mailbox and all other directories in the path of the mail box". Are these "virtual" mailboxes or is there an actual folder/file for each box?

Here is the result of 'ls -la /var/vmail'
