I'm not sure this is the best place for this question, but I have googled around and can't seem to find a resolution to my issue. Please feel free to redirect me somewhere else if necessary. :)
So, I am hosting a mail server on Ubuntu 14.04, using postfix. I have noticed recently that I haven't gotten any mail since last week. In
I am seeing a lot of
milter-reject: END-OF-MESSAGE from localhost[127.0.0.1]: 4.7.1 Service unavailable - try again later;
messages. The only thread I can find about that particular error(https://serverfault.com/questions/676473/postfix-milter-reject-end-of-message-from-4-7-1-service-unavailable-try-again) says to move from DKIM to OpenDKIM. However, I am already using OpenDKIM, so that (probably) isn't the issue.
I have also noticed that the messages are sitting in
but have no idea how to get the out of there/why they are there. There are some errors saying that the following destination in unwritable, but I have given it the correct permissions now ... I think.
/var/lib/spamassassin/sa-update-keys/ root@ip-00-00-00-00:/var/spool/postfix/maildrop# ls -l /var/lib/spamassassin/sa-update-keys/ total 8 -rw------- 1 spamd spamd 2783 Oct 28 2015 pubring.gpg -rw------- 1 spamd spamd 0 Oct 28 2015 pubring.gpg~ -rw------- 1 spamd spamd 0 Oct 28 2015 secring.gpg -rw------- 1 spamd spamd 1200 Oct 28 2015 trustdb.gpg
I've tried restarting all the services, and reboot all to no avail. I'm a little stuck on where to go now, so any help would be appreciated.
