I wonder how many sites there are where you just can't tell anyway.

FastMail doesn't even listen on port 143, because it leaks cleartext passwords to active attackers:

And even once you try port 993:

* OK IMAP4 ready
. CAPABILITY
* CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID ENABLE UIDPLUS SASL-IR AUTH=PLAIN
. OK completed

You're talking to nginx.  It's only once you log in that you see what's really there:

. OK [CAPABILITY IMAP4rev1 LITERAL+ ID ENABLE ACL RIGHTS=kxten QUOTA MAILBOX-REFERRALS NAMESPACE UIDPLUS NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND BINARY CATENATE CONDSTORE ESEARCH SEARCH=FUZZY SORT SORT=MODSEQ SORT=DISPLAY SORT=UID THREAD=ORDEREDSUBJECT THREAD=REFERENCES ANNOTATEMORE ANNOTATE-EXPERIMENT-1 METADATA LIST-EXTENDED LIST-STATUS LIST-MYRIGHTS WITHIN QRESYNC SCAN XLIST XMOVE MOVE SPECIAL-USE CREATE-SPECIAL-USE DIGEST=SHA1 LOGINDISABLED XCONVERSATIONS COMPRESS=DEFLATE X-QUOTA=STORAGE X-QUOTA=MESSAGE X-QUOTA=X-ANNOTATION-STORAGE X-QUOTA=X-NUM-FOLDERS IDLE] User logged in SESSIONID=<sloti30t15-1470551-1427153102-1-6352514379123523087>
