Re: Help with from=<> spam

Upgrade iRedAPD to 1.6.0, then enable plugin `reject_null_sender` in /opt/iredapd/settings.py.

Re: Help with from=<> spam

Thanks for your reply Zhang,

I was planing to upgrade (do-release-upgrade) this weekend so I have a newer PHP etc and then to upgrade to the latest iRedAPD , iRedMail, iRed-AdminPro.

I have a few concerns with doing a dist upgrade also as I need to migrate to nginx first also.

Are you available over the next 2 or 3 days for (paid) remote support if required?
Do you know of any issues arising when upgrading from ubuntu 12.04 to 14.04 lts?


Thanks again

Re: Help with from=<> spam

Migrating from iRedMail-0.9.0 (old server) to iRedMail-0.9.2 is easy. How about install the latest iRedMail release on new server, then migrate old server to new server? It's much easier than an Ubuntu dist-upgrade.

We offer paid migration support if you need:

Re: Help with from=<> spam

Thanks Zhang,
We are planning to move to a more robust setup in the near future (2VMs + MySQL Cluster + Shared Mailbox Storage + Keepalived failover) but need to keep this system running for a short while yet.

Went to upgrade the other night (iRedMail 0.9.0 > 0.9.1) and found I am missing php5-intl which is only available with PHP 5.4+ (I am running 5.3 currently) so couldn't start the first step until I upgrade PHP.
But, at the same time I need to migrate to nginx etc so figured it was easier to do it in one run (including OS).

Anyway will upgrade iRedAPD this evening as this is very straight forward and look at migrating soon.


Thanks

Would you mind sharing this deploy document?
