Plesk Greylisting blocks ‘pool’ issue with outlook cloud services

Today I got an SMS that my mailserver was bouncing mail from someone. In first instance it was unclear to me why it was blocked, but after analyzing further I found out that by default the cloud outlook mailservice of microsoft is being blocked by many mailservers. Because the name of the server is using ‘pool’ in the domainname lookup:

greylisting filter[539]: list type: black, from:, match string: dsl|pool|broadband|hsd

So missing important emails is a big failure and even a bigger bummer when you do not know exactly why. Ok I added the mail adres in the whitelist, but it would be better to allow such kind of domains sending mail.

So how to do this in plesk with greylisting?

See first with ./greylisting -i (info-Server) that it is indeed blocked

./grey_listing –update-server -domains-blacklist del:”dsl|pool|broadband|hsd”

this will remove it and with ./grey_listing -i you can see

Beetje ziek van

zucht .. heb ik weer

The error that the other server returned was: 550 550 SC-001 Mail rejected by Windows Live Hotmail for policy reasons. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation problems. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit for email delivery information and support

Nou mensen .. hotmail heeft weer eens doen besluiten dat mail vanaf niet bij gebruikers mag binnenkomen. Ondanks SDF en andersoortige perfecte mailserver instellingen. Als Microsoft daar nu ook eens gewoon een ge-automatiseerd systeem van zou maken om je IP uit de ‘blacklist’ te kunnen laten filteren dan zou dat veel ergenis en FTE’s schelen.

(jij als of gebruiker kan natuurlijk ook gmail gaan gebruiken ;-))

Message to self: Fixing POP3 Mailserver issues

This afternoon the maillog showed some wierd issues, and I could not get the mail through the POP3 server.

pam(dennis,192.16x.x.xx): PAM child process 7842 timed out, killing it
wb dovecot: auth(default): pam(dennis,192.16x.x.xx): Child process died
wb dovecot: auth(default): PAM: Child 7842 died with signal 9

Took me some time to find out that I had to recover a ‘database’ ? Finally this is the solution (CentOS / Bluequartz)

service dovecot stop
service xinetd stop
service admserv stop
killall -9 dovecot-auth
/etc/rc.d/init.d/dbrecover start
service admserv start
service xinetd start
service dovecot start

Archiving the E-mail


[hit image to enlarge]

I am using Copernic and I just discovered that my e-mail was not indexed properly. Some dude decided to disable the indexing of mailboxes >50MB .. Uch..
I use Outlook for several years now and I do not remove important business e-mail (never) .. so I have years of e-mail collected… Right now almost 100.000 e-mails (spam removed mostly)
wow.. and the keywords.. Finally I can find stuff again (b.t.w. my system is still indexing and I think Copernic will need more days / weeks to complete the total index of all archives.

Is there no better / faster way?
