known bug #90 - any solution to IMAP "SEARCH ALL" truncates output on large boxes ?

Known bug #90 was reported in 2014. However it still occurs in 2019. Does
anybody know how to overcome this situation?

When a search in a mailbox returns a large number of messages UID, I get
multiple lines with the error:
"Excessive server response line length received, 51752 bytes. Stripping ".

In my case, I was searching for UNSEEN messages.

It was supposed to return more than 6,000 messages UIDs, but I only get
1,183 UIDs after the lines indicating the stripping.
