Syntax error in BODYSTRUCTURE. Unexpected token: '(' about mailkit HOT 4 CLOSED

Thanks for your awesome work. a 💕 Dinner for Two 💕 is on the way to you :D

from mailkit.

Based on the exception, the issue is with parsing the BODYSTRUCTURE portion of the response.

Luckily, your log has only 1 FETCH response, so it means it has to be this:

BODYSTRUCTURE (("text" "html" ("charset" "utf-8") NIL NIL "base64" 38706 497 NIL NIL NIL ()) ("image" "jpeg" ("name" "image003.jpg") "<[email protected]>" "image003.jpg" "base64" 3446 NIL ("inline" ("filename" "image003.jpg" "size" "2782" "creation-date" "Thu, 22 Mar 2012 13:56:38 GMT" "modification-date" "Thu, 22 Mar 2012 13:56:38 GMT")) NIL ()) ("image" "jpeg" ("name" "image004.jpg") "<[email protected]>" "image004.jpg" "base64" 3446 NIL ("inline" ("filename" "image004.jpg" "size" "2782" "creation-date" "Thu, 22 Mar 2012 13:56:39 GMT" "modification-date" "Thu, 22 Mar 2012 13:56:39 GMT")) NIL ()) ("image" "jpeg" ("name" "image005.jpg") "<[email protected]>" "image005.jpg" "base64" 3232 NIL ("inline" ("filename" "image005.jpg" "size" "2625" "creation-date" "Thu, 22 Mar 2012 13:56:39 GMT" "modification-date" "Thu, 22 Mar 2012 13:56:39 GMT")) NIL ()) "related" ("boundary" "_004_7D3F5AE184118942976793FC500B8F4A402D17DB3PRD0702MB097eu_" "type" "text/html") NIL ("de-DE") NIL)

From just looking at it, I suspect the issue is the () parts. the IMAP protocol is a very LISP-like syntax and so anything in ()'s is a "list" of some type. Empty lists (at least in the IMAP specification), are generally required to be represented by a NIL instead of (), and that's probably why things are blowing up.

Any ideas, if this can be fixed, or maybe even message could be ignored somehow?

My initial assumption based on what I'm seeing in the log is that yes, this server bug can be worked around.

I'll work on a fix shortly.
