A have a Qmailtoaster installation on Centos 4.3.
It worked excellent for a couple of months but since yesterday
clients started to fail sending messages with Thunderbird giving the
following message:
Sending of message failed.
The message could not be sent beacuse connecting to SMTP server
mail.hidraulica.ro failed. The server may be unavailable or refusing
SMTP connections.
I didn't make any changes to the server. There is no problem with
receiving messages. I don't know what to look for in the log. Since
now I don't see in the log any error, or failure or anything...
If you're sending from somewhere that has a dynamic IP (your house,
cable modem, DSL, etc.) then zen.spamhaus is probably blocking it.
Remove that entry from your blacklists file and try.
Jave (and Istvan),
There seems to be a problem with the blacklists servers. I had to
remove all but "-r bl.spamcop.net" from my blacklists file this
morning to get SMTP to work in a timely fashion.
Anyone know what is up with the blacklist servers or if we should be
moving to different ones?

Indeed it was the problem with the one of the blacklist servers. I
figured that out after swearing for 3 hours and reading 1000 threads on
the mailing list.
Also there was in the log /var/log/qmail/smtp/current , status 256
instead of status 0 of the sent mails, which suppose to be a time out
or something. Maybe someone can confirm it.
I your opinion, when the email functionality is critical, does it worth
to use blacklists or not?
I had quite a few situations when critical mails didn't arrive because
of this blacklists, then I said is better to receive more spam, than
miss critical mails.
Some experts say that SpamAssassin is a bullsh*t. Is that correct??
Which blacklists are 100% accurate(they never block a non-spam), even if
they are weaker than others??
I see that the latest realease of qmail-toaster is using only
zen.spamhaus and according to Jake is blocking dynamic IP-s. Why did you
decide to use this blacklist in the latest release??
