eircom.net relays on www.spamhaus.org

[padraig]

We have an eircom.net zimbra6.08 issue. it appears some eircom.net relays are registered as spam relays at spamhaus.org.

So some e-mail from eircom.net arrives and some is rejected

we even have an issue where some CC:'ed users receive the e-mail and some don't, has anybody else experienced this ?

Perhaps they are but isn't this something you need to address at spamhaus? In any case, they should be on the RBL if they've been detected as sending or allowing spam - is that likely to be the case.

Thanks phoenix,

Yes it appears they are on RBL

We use SMTP mailhubs as our edge servers - this rejects the RBL's -
Is it possible to white list say *ercom.net in sendmail ?

I don't really know anything about sendmail but this thread appears to cover what you need. Have you considered using something like mxHero for the edge servers?
