OK.
I tried. My commands:
1 LOGIN "user" "password"
2 SELECT "SENT"
3 UID FETCH 41827,41861:41862,41870 (UID RFC822.SIZE FLAGS ENVELOPE
BODY.PEEK[HEADER.FIELDS (REFERENCES)])
4 LOGOUT
And I get glibc error
I attach file with output from command:
valgrind --leak-check=full -v \
--show-reachable=yes /usr/local/sbin/dbmail-imapd -n
Give me instructions, how can I help you
