| Post subject: | Problems with email after kernel upgrade |
After I upgraded the kernel (http://blog.linode.com/2009/08/17/new-k ... abilities/), I started having problems with the email accounts hosted on my Linode. I still haven't been able to determine the cause. My setup is based on the instructions at: http://workaround.org/articles/ispmail-etch/ The first problem that I noticed was that emails would send but never be received. Looking at the log, I saw that outgoing emails were being delayed. I couldn't determine the cause, but restarting the virus scanner by running "/etc/init.d/amavis restart" fixed this. Almost everything appears to be back to normal. The last problem that I have noticed is that sending from SquirrelMail to email addresses hosted elsewhere results in the message "Transaction failed 554 5.7.1 <user@example.com>: Relay access denied". Sending from my normal mail program works. I didn't change anything in my setup, and can't see anything wrong with my configuration. Any ideas why a reboot would cause these problems and how to fix them? I've spent hours on this, and can't find anything wrong. Thanks![/code] |

I don't know what the solutions to your problems are, but they don't have anything to do with the kernel update. I think it's likely that configuration changes were made some time ago but not applied, and they were applied on the reboot. |

That sounds reasonable. I wouldn't expect it to have anything to do with changing a kernel, but I also don't think I changed anything after the last time the mail server was restarted. I can't see any reason I would have had to manually restart AMaViS after rebooting. Now that it is working, I still can't see any reason why SquirrelMail won't send to other domains. |

You'll need to tell us what MTA you're using and some more info (I'm not reading that tutorial). Guessing that you're using Postfix, please post the output of Code: postconf -n Also post the FULL log line that says "relay access denied" and a couple before & after it. We need to determine who is denying you: your server or the remote. I'm guessing your "mynetworks" setting is now incorrect, or that you've lost "permit_mynetworks" in any of the smtpd_*_restrictions lines. Again, assuming Postfix. |

Aha! Yes, I'm using postfix. I'm new to email admin, so I didn't notice the missing "permit_mynetworks". I added that, and everything is working the way I want it to. Thanks! |

Just be careful you're not making yourself into an open relay. If you want more eyes on your config to help check, post the output of postconf -n. |
