How do I test an imap server?

Each line you type is in bold:

The "abc1" etc at the begining of each command is just a tag you make up. Supposedly it should be unique for each line; I've found you can actually use the same tag over and over again.

telnet 143
Connected to (
Escape character is '^]'.
* OK IMAP4rev1 v12.264 server ready
abc1 login linda AFr54Tui8
abc1 OK LOGIN completed
abc2 select inbox
* OK [UIDVALIDITY 1020929003] UID validity status
* OK [UIDNEXT 1020929444] Predicted next UID
* FLAGS (\Answered \Flagged \Deleted \Draft \Seen)
* OK [PERMANENTFLAGS ()] Permanent flags
* OK [UNSEEN 2] first unseen message in inbox
abc2 OK [READ-WRITE] SELECT completed
abc3 fetch 2 body[text]
* 2 FETCH (BODY[TEXT] {25}

This is just a test

* 2 FETCH (FLAGS (\Recent \Seen))
abc3 OK FETCH completed
abc4 close
abc4 OK CLOSE completed
abc5 logout
* BYE IMAP4rev1 server terminating connection
abc5 OK LOGOUT completed

Note that if your server only accepts secure IMAP, you'll need to use openssl instead of telnet:

openssl s_client -connect

Then proceed as above.

Keeping URIs so that they will still be around in 2, 20 or 200 or even 2000 years is clearly not as simple as it sounds ... However, all over the Web, webmasters are making decisions which will make it really difficult for themselves in the future. (Tim Berners-Lee)
