Multiple MX records in DNS and MySQL

[jockstrap]

I'm finding that I am getting multiple occurences of the MX record in my dns zones..

I found that each time I tick the DNS-MX box in the co-domains properties, it adds another MX duplicate record to the database.

I then have to delete it from the database manually using phpmyadmin.

eg: main domain = www.mydomain.com

I added blog.mycomain.com as a co-domain and ticked both DNS options.
This creates a duplicate line in the DNS of;

MX 10 hostname
MX 10 hostname

Seeing I was playing with the MX option on the co-domains - I ended up with 10 duplicate records in the DNS :(

Has anyone else experienced this and if so is there a fix for it ?

Thanks...

May have worked it out...

Have not been deleteing them from the recycle bin in the dns manager - lol..

How long to items stay in the recycle bin ???? Indefinitely or is there a cron timer or something to delete them after a certain time period ?

[till]

Items stay in the recycle bin until they where deleted manually.
