Looks like a bug in dovecot. Which version? Do you use some proxy?

[rafalm]

I use dovecot 1.2.1
no proxy
php server & imap server is in the same machine

[alec]

What PHP version? I've searched dovecot's source code, there's no "FTP" string.

Unusual behavior with your Dovecot... My dovecot v1.2.4 doesn't return this "FTP" string (1). Try to update your installation and review your "dovecot.conf" please.

(1) $telnet mail.***.com.br 143
