You can safely ignore the "Authentication warning".  Normally it does
not interfere with deliverance/delays.

Please be more specific:  What version of sendmail?  What version of
IMAP server?  Which delivery method: direct via deliver(8), filtered
through some procmail(1) mechanism or sent by LMTP (without deliver)?

Please give the appropriate snippet of your sendmail.mc that corres-
ponds to IMAP server delivery as well.


(Hint: you may also try this question on sendmail mailling lists, they
 know a lot more about .mc-file configuration)
