Port 993 is oldschool.
Did you try 143 with STARTTLS?

Hello,

this is my working config:

imap_host = "imap.strato.de"
imap_port = 993
imap_secure = "SSL"
imap_short_login = Off
sieve_use = Off
sieve_allow_raw = Off
sieve_host = ""
sieve_port = 4190
sieve_secure = "None"
smtp_host = "smtp.strato.de"
smtp_port = 587
smtp_secure = "TLS"
smtp_short_login = Off
smtp_auth = On
smtp_php_mail = On
white_list = ""

if you are using your own domain setup, you have to create an alias.
