dovecot - Oct 2018 - Panic: file istream-crlf.c: line 24 (i_stream_crlf_read_common): assertion failed: (ret != -2)

Hello,

cannot fetch mails from an IMAP folder because of the error in the 
subject - fetching always stops with SIGABRT.

Could anybody help me, please?

Kind regards

Peter

We need more information than that:

- Your configuration and version, which is privided by the output from 
`dovecot -n`
- Steps to reproduce, e.g the email message and what was happening when 
this problem occurred.

Regards,

Stephan.

Hello Stephan,

thank You for Your reply! If You need more information, just tell me how 
to get it - I'm not an email administrator, just trying to hold and 
serve my emails privately without needing to buy extra disk space from 
my provider.

To reproduce the abort, You'd probably need to fetch the original email 
- it's from the tomcat users mailing list (there're more than this one, 
but after this first fetching aborts):
