[Dovecot] SiS: Attachment file larger than expected

[Andrew Lewis]

I recently set up SiS and imported a large chunk of mail.

I've noticed one or two instances of this in the logs:

Mar 28 09:03:50 mail dovecot: imap(xxx at yyy.zz): Error: Attachment file /mailstore/attachments/ce/73/ce737a45fe07495e2ae6466f9e381a30d5ec300406f11269d79bd5608cc0c922-822b3d2df67f8e4d7f5000009501e12a larger than expected (252218)
Mar 28 14:52:34 mail dovecot: pop3(zzz at xxx.yy): Error: Attachment file /mailstore/attachments/c5/e1/c5e13d671d1d796680ae7166363afcb819af3d9cd04e01de7d65031b2f732bdf-b2ecf918b910904d826200009501e12a larger than expected (143959)

Could that be an indication of a hash collision? No problem reports from the affected users. 

Output of du -b below:

186572  /mailstore/attachments/ce/73/ce737a45fe07495e2ae6466f9e381a30d5ec300406f11269d79bd5608cc0c922-822b3d2df67f8e4d7f5000009501e12a

Both attachments are PDF documents. I'm using Dovecot 2.0.11 + changesets d3d6ed6d268b and 890a46b3ab63 from git.
