Hello *, what might be the reason for the following problem: Two systems with self-compiled cyrus-2.3.16 (both with Solaris 10) give different responses to IMAP commands. The example is for the "logout" command but all other IMAP commands are also affected. [root@mailbackend-a /]# telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID MUPDATE=mupdate://mupdate-febe.intern.tu-berlin.de/ AUTH=DIGEST-MD5 SASL-IR] mailcluster2.intern.tu-berlin.de Cyrus IMAP4 (Murder) v2.3.11 server ready . logout * BYE LOGOUT received . OK Completed <--- This looks OK Connection to localhost closed by foreign host. [root@mailbackend-a /]# [elsnccpa@mailbackend-2 ~]$ telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID MUPDATE=mupdate://mupdate-febe.intern.tu-berlin.de/ AUTH=DIGEST-MD5 SASL-IR COMPRESS=DEFLATE] mailbackend-2-febe.intern.tu-berlin.de Cyrus IMAP Murder v2.3.16 server ready . logout * BYE Unknown code imap 54 . OK Unknown code imap 55 <--- This is ugly Connection to localhost closed by foreign host. [elsnccpa@mailbackend-2 ~]$ What might be the error in compilation or install that prevents correct mapping to the human-readable text? Thanks in advance for any pointer towards a solution, Frank Elsner ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
