Some of you that have been migrated to IronPort already may already have noticed that there is no longer a 'List' tab in the Manage My Mail interface.
We found out during early testing that accounts with mailing lists on them broke after we moved them across to the new platform. Email and spam filtering was fine and you could send subscribe/admin commands to the list and receive a response, but when you tried replying to one of these responses the message was getting routed to the catch all mailbox on the the account (assuming it was switched on) instead of the mailing list software.
As an interim measure, we've implemented some LDAP routing changes that allow existing mailing lists to carry on working to a certain degree but these changes don't let you create new lists, and at the moment you have to have catch-all switched on (we're trying to fix this at the moment). It's for this reason that we're not going to migrate mailing list users until the end.
There are 1257 accounts with mailing lists - 755 have catch-all enabled, 502 have it disabled.
So basically, you'll only have access to the mailing list controls after migration if you're already using mailing lists. We still need to update the support content for this and it looks like we missed one of the links in Manage My Mail that takes you to the mailing list creation pages but this should be sorted soon.
Even assuming we do manage to completely fix lists for existing users there's a good possibility that we'll be looking to decommission the service in the new year anyway. Either that or offer an alternative (the Plesk PAYH platform has mailing list support for example).
We're still batting ideas around at the moment, but the consensus at the moment is to decommission the service. I just thought I'd give you guys visibility of this to see what your thoughts/opinions/suggestions were?
It's worth noting that this doesn't affect our My Circular or Net Announce service.
