I can confirm this bug “Fatal error: Call to undefined method wpdb_drivers::get_col_length()” and that updating to plugin version 1.9.2 fixes it for me – thanks.

Have you looked at using a transactional email service like Mandrill?

For the volume of emails you’re sending, it probably will cost – you get 12,000 sends per month for free, pricing then starts at $0.20 per thousand emails sent.

There is a plugin for WordPress – wpMandrill which makes it easy to set up email delivery via Mandrill.

Okay, so if I go into the moderation part of admin, I can manually approve those trackbacks. Fine, trackbacks are working.
However, if trackbacks are treated just like comments, then when the trackback notification gets sent out by email, it should include the links to approve or reject – just like other comments.
This is why I thought it wasn’t working.
So I change the problem:
The problem is that trackback moderation can only be done through the admin interface and not via email like regular comments. Can this be fixed please ?

Yes and yes.
Manual comment moderation is turned on.
The trackbacks are indeed in the database.

Yup, I just discovered it displaying correctly in Firebird after a refresh before I saw your comment.
I’ve noticed Firebird is rather aggressive at caching stuff – possibly why it’s so fast, but can cause problems for major page redesigns.

Nope, not only you, I just upgraded and got exactly the same result.
WP devs – please don’t make me use IE to post on my blog ! Fix it please – I’m begging you ! ??

When you try and set the “time_difference” field in the “other options” page, to something like 17, you get the error “time_difference is outside the valid range (-13 – 13).”
This is definitely a bug – it seems an assumption was made in development that 12 hours (or so) either side of GMT was all that was required.
Which would be fine if we were setting times relative to GMT, but we are not, we are setting them relative to the timezone of the server, so a range of -24..+24 is what is required to cater for all possibilities.
For now I’ll try manually editing the database.

Another thing you could check for an automated “suspicious comment” filter – is to check for the number of links added to the comment.
Most comment spammers seem to be trying to take advantage of the google weighting of blogs by increasing the number of links to their sites, thereby making their results appear higher in the google hit list.
Anyone with more than two links in a comment is highly likely to be spam in my opinion.
