Problem
If you use http://www.emclient.com/" title="eM Client">eM Client to access our standard POP3/IMAP email accounts, you may occasionally get the error message stating Connecting to mail account failed (see screenshot below).
Under the Log tab, you may see entries of MailExceptions.ConnectionExceptions followed immediately by (Connection Terminated)
If you enable diagnostic logging in eM Client, you should find the following entry in the log file:
21:20:57.389|053| )
21:20:57.389|053| Exception:

21:20:57.389|053| Greetings * OK Calzada Media (mail.calzadamedia.net) IMAPv4
Cause & Solution
At this time, we believe this issue is being caused by a bug in the software that powers our mail services. This is a known bug that only affects IMAP connections and the software developers have stated it will be addressed in a forthcoming version.
This bug will not cause you to lose any messages. If a message fails to sync, eM Client will automatically re-attempt synchronisation. If you have any concerns about missing messages, please check your account using Webmail.
