We've been forced to blacklist mail destined to addresses @laposte.net.
We are intervening.
Update(s):
Date: 2015-01-16 12:36:47 UTC All IPs have removed from the black list.
Date: 2015-01-16 03:44:57 UTC Much of the IP were unblacklisted.
The rest will follow soon, we expect a full return to normal situation by tomorrow.
Date: 2015-01-14 10:58:56 UTC We've established a first contact, they have accepted to de-blacklist some if our e-mail infrastructure (/24)
Of course this is not sufficient because our customers with dedicated servers, VPS, private and public cloud, xdsl still cannot send emails directly from their infrastructures to @laposte.net addresses.
We confirm that dialogue will continue with them.
Date: 2015-01-14 06:49:36 UTC 554 lpn-prd-vrin001 ESMTP not accepting connections
421 4.7.0 lpn-prd-vrin001 Error: too many errors
it seems to be infrastructure problems .. aie :(
Date: 2015-01-14 06:48:44 UTC We contacted laposte.net to understand the problems. There is no one that seems to answer our questions. It looks like a stroke of anger of their network administrator who had bad celebrations in the end of the year.
If you know how to get in touch with people who manage laposte.net , please keep us informed.
