Hiya,

I think I have found it...

I have a lot of items in my test Exchange Server and noticed that the output, whilst not truncated through a message UID, didn't seem right.

As such I then ran curl with the verbose (-v) flag and noticed the following in the output:

< A003 OK [READ-WRITE] SELECT completed.
> A004 SEARCH ALL
* Excessive server response line length received, 8760 bytes. Stripping
* Excessive server response line length received, 16384 bytes. Stripping
* Excessive server response line length received, 16384 bytes. Stripping
* Excessive server response line length received, 16384 bytes. Stripping

A quick search of the code reveals that pingpong.c contains some truncation code, at line 408, when it deems the server response to be too large truncating it to 40 characters at line 418 :(

I will investigate further and try and come up with a fix.

Cheers

Steve

note that between "13" and "48272" is "1" (probably last digit from "48271"). 

When I try to connect directly, the IMAP server returns all 48k messages :
