Hello dovecot gods, after using Postfix with webmail for 8 years the new gen of email smartphones forces me to consider using IMAP. Actually, for several months I was successfully using IMAP. I believe the reason why IMAP worked previously (before migrating to the Cloud) the hosting server and the client machines were considered local by the system. Now, I have moved everything to a Cloud service. And, now attempts to use my Ubuntu Evolution or iPhone generates the following error condition in my logs:

dovecot: auth(default): client in: AUTH	1	PLAIN	service=imap	lip=xxx.yyy.www.zzz	rip=	lport=143	rport=59107	resp=AGRhdmlkAGx1dGVmaXNr
