No. Not when they claim that sendmail does precisely the same thing, and I can easily demonstrate from the RELEASE_NOTES that this changed in 8.10 (previously, I think sendmail checkpointed after every ten recipients, but in order to prevent possible problems where an error partway down the list could wind up with a copy of the message being re-delivered every time to all recipients above the problem one and after the last checkpoint, they changed SuperSafe to be true). > With disk failure rates being what they are, and the uptime some > people get, I don't think the normal MTA behavior helps very much > anyway. It is an option though, just not the default. Linux async mounts still trash filesystems. If you don't care about that, that's fine. But then you've got no business writing an article for a magazine like _SysAdmin_. > Obviously these people want to sell a product, and they don't care > what they have to do to make that product look good.

You haven't been watching the responses from one of the authors on the mailing list set up to discuss this article (as requested by the folks at _SysAdmin_). He really is clearly clueless with regards to benchmark tuning, FreeBSD in general, and proper operation of SMTP MTAs. I would invite you to send your own letter to the publishers of _SysAdmin_, which will get forwarded to the mailing list, which you will then probably be subscribed to. Then you can see the cluelessness for yourself. -- Brad Knowles, /* efdtt.c Author: Charles M.
