Spamassassin issue ? not delivering to Gmail

[jorgece]

Hi,
I'm totally lost here.
My server ( centos5, updated 10.4 Plesk, Qmail ) stopped delivering emails to Gmail 2 days ago.
All it shows is:
deferral: System_resources_temporarily_unavailable._(#4.3.0)/

Still:
1.- It receives Gmail emails successfully.
2.- I CAN telnet successfully and even managed to manually send an email to a Gmail account directly from telnet.

White listed Gmail in spamassassin and turned off APF without success.

Any idea anyone???

TIA

This might be the IPv6 bug Parallels had to fix in qmail. Do you have all the micro updates installed?

Yeah qmail + ipv6 is absolutely not going to work

Thanks for your prompt answer.

Yes, Plesk is up to date including all microupdates.
Somewhere I read about this IpV6 thing and proceeded to turn IpV6 on, but got "kernel not compiled for IpV6".

Any idea where to head from here?

TIA

Solved!!

Thanks for your input, you were right.

For the record:
Erased the last three lines of /etc/modprobe.conf

alias eth0 e1000
alias scsi_hostadapter mptbase
alias scsi_hostadapter1 mptspi
alias scsi_hostadapter2 ata_piix
alias net-pf-10 off -----erased from here down
alias ipv6 off
options ipv6 disable=1

AND REBOOTED the server.
In my first try only restarted the network which did not do the trick.

Thanks again.
Saludos,
