[Koha-devel] [Koha] DBMS auto increment fix not working

[Michael Kuhn]

Hi Marcel

Unfortunately it seems like the mailing list is not accepting my 
original answer to your e-mail (I tried twice). Instead after some days 
I received an e-mail with the subject "Undelivered Mail Returned to 
Sender", telling me

The mail system

<koha at lists.katipo.co.nz>: connect to lists.katipo.co.nz[202.70.130.220]:25:
     Connection refused

I don't even know if this e-mail is getting through. There's probably 
something wrong with the mailing list when not accepting answers.

Best wishes: Michael
