No problem!

My system is similar: Debian testing with the OpenSSL 1.1.1d from the
distribution. I have no build problems whatsoever. OpenSSL comes with
backward compatibility macros that most allow code written for 1.0.2 to
be compiled without errors. These macros can be turned off by changing
the API compatibility version using -DOPENSSL_API_COMPAT=<version>.

You can check this with

    make V=1 imap-send.o

This will show the compiler command executed:

    gcc -o imap-send.o -c -MF ./.depend/imap-send.o.d -MQ imap-send.o
-MMD -MP   -g -O2 -I. -DHAVE_SYSINFO -DGIT_HOST_CPU="\"x86_64\""
-DHAVE_ALLOCA_H -DUSE_CURL_FOR_IMAP_SEND -DSHA1_DC
-DSHA1DC_NO_STANDARD_INCLUDES -DSHA1DC_INIT_SAFE_HASH_DEFAULT=0
-DSHA1DC_CUSTOM_INCLUDE_SHA1_C="\"cache.h\""
-DSHA1DC_CUSTOM_INCLUDE_UBC_CHECK_C="\"git-compat-util.h\"" -DSHA256_BLK
-pthread -DHAVE_PATHS_H -DHAVE_STRINGS_H -DHAVE_DEV_TTY
-DHAVE_CLOCK_GETTIME -DHAVE_CLOCK_MONOTONIC -DHAVE_GETDELIM
'-DPROCFS_EXECUTABLE_PATH="/proc/self/exe"'  -DFREAD_READS_DIRECTORIES
-DNO_STRLCPY -DSHELL_PATH='"/bin/sh"' -DPAGER_ENV='"LESS=FRX LV=-c"'
imap-send.c

Check it for any -D flags mentioning OpenSSL.

You can get even more verbose output from gcc by copying the compiler
command make displays and running it after appending the verbose flag
"-v" at the end.

Check this new output for include directories etc. You need to make sure
that gcc picks up the system OpenSSL include files. They should be found
under /usr/include/openssl.


Hope this helps,
