dovecot - Aug 2012 - Length of attachment filenames

Hi there,

 

I have a beginners question to Dovecot: does it have a restriction on
the supported length and character encodings of filenames of
attachments?

Can filenames be arbitrary large?

 

Cheers,

Hauke

The filenames in IMAP's BODYSTRUCTURE reply probably get truncated somewhere
around 8192 bytes (then again, maybe not, depends on the encoding I think). And
in any case not all IMAP clients use BODYSTRUCTURE.

The maximum filename length depends largely on the file system:
