We have our servers IPs at OVH IP address-space and from time to

folder no-matter-what.
the best solution for this is to configure sender protection via spf/dkim
records, and when possible, using IP addresses not listed in any
blacklists.
Of course, our systems use spf, dkim, dmarc, srs, dns and rdns in order
and not in any known blacklist. we enforce sending limits to all our
users and we do not host mailing lists or bulletins. However, from time
to time all messages sent from some domains we host (not all domains) in
the same IP go filtered to SPAM.
In any case, and although I know this may be out of the scope for this
list, could anybody be so kind and check tere's trouble anywhere with
this domain?

Thanks very much in advance
The ip address is listed at dnsbl.spfbl.net with code 127.0.0.4
Didn't know about that one. It assumes we do not have an MTA on that IP.
I've already requested unblocking.
Thanks
Ignacio
