Help interpreting two error messages: NOQUEUE:SYSERR and Authentication-Warning

Recently one of my SmartList mailinglists behaved strangely. On a weekly, announcement-type list, one posting did not get sent to my own organization. Subscribers at my organization make up 24 of the 1188 total subscribers to the list. I can't find any evidence in the mail log that the posting was even attempted to my organization. However, bounce messages got through normally to the list's owner at this same address.

One unusual entry in the mail logs came just after the posting was received at the mailinglist's address:
Nov 11 12:37:39 mailinglists sendmail[511]: NOQUEUE: SYSERR(slist): Arguments too long
Nov 11 12:37:39 mailinglists sendmail[510]: NOQUEUE: SYSERR(slist): Arguments too long
Nov 11 12:37:39 mailinglists sendmail[509]: NOQUEUE: SYSERR(slist): Arguments too long
Nov 11 12:37:39 mailinglists sendmail[512]: NOQUEUE: SYSERR(slist): Arguments too long
Nov 11 12:37:39 mailinglists sendmail[513]: NOQUEUE: SYSERR(slist): Arguments too long
Nov 11 12:37:39 mailinglists sendmail[514]: gABHbd2w000514: Authentication-Warning: mailinglists.jhuccp.org: slist set sender to [email protected] using -f

Can anyone help me understand these two different error messages, and whether they could be connected to this problem? Are there any ways to modify SmartList or sendmail to correct this problem? I searched my sendmail book, the SmartList FAQ and Google on these terms, but came up empty.

Thanks for your help.
