Description: ------------ In connection/login process we have at least two redundant CAPABILITY calls. Here's how it looks now: S: "IMPLEMENTATION" "Cyrus timsieved git2.5+0-Kolab-2.5-96.el6.kolab_3.4" S: "SASL" "PLAIN LOGIN" S: "SIEVE" "comparator-i;ascii-numeric fileinto reject vacation imapflags ... S: "STARTTLS" S: "UNAUTHENTICATE" S: OK C: CAPABILITY S: "IMPLEMENTATION" "Cyrus timsieved git2.5+0-Kolab-2.5-96.el6.kolab_3.4" S: "SASL" "PLAIN LOGIN" S: "SIEVE" "comparator-i;ascii-numeric fileinto reject vacation imapflags ... S: "STARTTLS" S: "UNAUTHENTICATE" S: OK C: STARTTLS S: OK "Begin TLS negotiation now" STARTTLS negotiation successful S: "IMPLEMENTATION" "Cyrus timsieved git2.5+0-Kolab-2.5-96.el6.kolab_3.4" S: "SASL" "PLAIN LOGIN" S: "SIEVE" "comparator-i;ascii-numeric fileinto reject vacation imapflags ...

Both starting TLS as well es logging in can result in a changed capabilities set. At least after STARTTLS the server must automatically advertise the latest capabilities, but in some versions of Cyrus this was broken, so we explicitely request those.

In which way it was broken? It returned wrong capabilities or what?
 [2015-01-22 16:13 UTC] yunosh (Jan Schneider)
No, it didn't advertise new capabilities after STARTTLS, so we had to explicitly ask for those.

So, there's no problem. The point is to not ask for them if they are provided in a response. I will work on this and provide a patch after the weekend.

This bug has been fixed in SVN. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
