[SOGo] Could not connect IMAP4

[Henry Verdonschot]

I'm trying to connect SOGo to our (Mailtraq) mailserver but I get the
address=<0x0x7f94cf08a8f8[NGInternetSocketAddress]: host=mail.ZZZ.nl
port=993>>
Apr 07 12:39:59 sogod [21827]: <0xCEF48268[SOGoMailAccount]:0> renewing imap4
password
2014-04-07 12:40:01.581 sogod[21827] ERROR(-[NGActiveSSLSocket
primaryConnectToAddress:]): couldn't setup SSL connection on socket
(error:00000005:lib(0):func(0):DH lib)...
Apr 07 12:40:01 sogod [21827]: [ERROR]
host=mail.ZZZ.nl, user=UUU, pwd=yes

I can connect to the server using Thunderbird IMAP
Any suggestions what I'm doing wrong here?

Is there SSL transport encryption enabled at that port?
How does your SOGo config look like?
Kind regards,

Yes, the settings for this service are to use Implicit mode (SSL/TLS,
IMAP4S). The config is as follows:

SOGoTimeZone = Europe/Amsterdam;
SOGoMailDomain = procura.nl;
SOGoAppointmentSendEMailNotifications = YES;
SOGoCalendarDefaultRoles = (
PublicViewer,
ConfidentialDAndTViewer
);
SOGoLanguage = Dutch;
SOGoMailingMechanism = smtp;
SOGoSMTPServer = mail.procura.nl;
SOGoSMTPAuthenticationType = PLAIN;
SOGoForceExternalLoginWithEmail = NO;
SOGoDraftsFolderName = Drafts;
SOGoSentFolderName = Sent;
SOGoTrashFolderName = Trash;
SOGoIMAPServer = "imaps://mail.procura.nl";
NGImap4ConnectionStringSeparator = "/";
