Dear all,
I am using Qmail on a Dell 2680 machine, this email server was running about
3 years but in this few days, qmail received mail very slow, I send the mail
through internel and intranet is the same, after 12 hours the mail can
recieved by the server. I try to clear the mailing list, and send a mail
through intranet, but the server cannot received it immediately, the mailing
list still empty, after few minutes the mail server queue many rubbish mail,
but didn't have my testing email on the list.
I check the /var/qmail/queue/lock/trigger, the permission is correct.
...
and I already check the DNS, the pop3 and smtp domain name is correct.
Can anyone have the same experience on it and give some suggestion.
I had such a problem once, the /var filesystem was almost full (95%)
acutally, as qmail never runs as root, it considered it as totally full
(the last 5% being usually reserved for root's only usage (depending on
filesystem formating options choices)) and so, althought everything
looked correct, qmail was very slow because it always had to wait until
a few bytes were freed (by sending/routing a message out and deleting it
from its queues) before receiving/accepting incoming messages
If this is the cas at your's, make sure to give more room to qmail by
increasing /var size or deleting/moving other files
