c082ae4ddc Parse server responses less strictly
Some servers send responses that are not standards compliant, but
contain extra SPACE, CR or LF characters, and by ignoring those
characters it might be possible to parse their responses.

3690506986 Ignore errors and retry later when in daemon mode
A persistent failure that could lead to a session not being able to be
recovered, or a failure during the login process (which is not covered
by the recovery function), would normally cause the process to
terminate.  This is expected when the configuration is run once, but not
desirable when running in daemon mode.

And thus just after the process has become a daemon, a session that
could not be restored, either because the connection to the server could
not be established or the login and its related negotiations failed, is
now disabled temporarily, and a recoqnection is attempted at the
beginning of the next daemon loop iteration.

There is one exception to that, and that is when there is an
authentication error, for example when a wrong username or password has
been supplied, and in this case the process terminates and a relevant
error is printed.

dba6d38403 Improve the failure handling during login/logout
Some of the requests/responses need to close connection, while some
don't.

Also, now a login error returns a different status value.

7496761c25 Check function return values during login/logout
The login and logout requests are not candidates for recovery, but the return
values of all the network functions that are called from inside them, should be
checked thorougly.

7435dc6d1d Add support to recover when BYE is received
Previously only network errors could cause a restoration of a session,
but now a BYE response sent by the server can also trigger it.

An option has been also added to control if and when the recover
function will be called.

716ee036dc Skip normal SSL shutdown only after an error
This disables the sending of the "close notify" shutdown alert, only
after a network failure took place, and not during normal closing of a

In case of a network failure during a logout request, there's no point
in restoring the connection, but it is better to just close it.

8c468f585f Fix the fatal failure caused by an SSL error
When a "Connection reset by peer" error was caused while reading through SSL, a
restoration of the session should have taken place after all the connection
related structures were resetted.  But instead a silent, unexpected and
unaccountable exit was the end result.  This was caused by the underlying
socket being closed while trying to shutdown the SSL session.

The session and selected variables should be reset if there has been a
connection problem or other failure.

The ifcore module methods that rely on the session should only be called
if there is a valid session variable defined.

It's better not to continuesly try to create a mailbox, when the server
continues to report TRYCREATE.

When appending messages it failed to create a mailbox when the mailbox
didn't exist and the server responded with TRYCREATE.

e907fe5fdf Make OpenSSL a mandatory requirement
There is no point in having SSL/TLS IMAP support as optional, it's as
useful if not more than the the non-encrypted connections.

The Makefile was better organized to make it easier to change some
options during compile.

The SHAREDIR variable passed as configuration option has changed name.
