[Dovecot] Attachment file larger than expected

[Angel L. Mateo]

Hello,

	I'm using dovecot 2.1.16 with SiS configured as:

mail_attachment_dir = <mypath>
mail_attachment_min_size = 128 k
mail_attachment_fs = sis posix
mail_attachment_hash = %{sha1}

	I'm having a few errors like:

Sep 18 15:46:32 myotis51 dovecot: imap(igd): Error: Attachment file 
/mail/users/attachments/16/b0/16b0b2023a903db14d7f7bcdb1cc04c3f67a4fcb-b32c0a2aa6ae39527c870000a9061514 
larger than expected (235866)

	They are really few and users haven't reported any problem, but the 
errors are there.

	In this case, actual file size of the attachment is:

amateo_adm at myotis51:~$ sudo stat 
/mail/users/attachments/16/b0/16b0b2023a903db14d7f7bcdb1cc04c3f67a4fcb-b32c0a2aa6ae39527c870000a9061514
   Fichero:

	and file is identified as:

MIME entity, UTF-8 Unicode text, with very long lines, with CRLF line 
terminators

	Any idea?
