Out of curiosity, is there a source for this? It's the first time I hear that 993/995 are not standard ports - and searching on the Internet, I can't find any evidence to back it up? Also, pretty much all email software has been using them for the past 20 years or so. It seems like a curiously high rate of adoption for a non-standard :-)
Hello,
IMHO the "not standard ports" is meant as "old, useless ports now".
So in short, ports 993/995 are IANA officially approved, and thus "standard". Further to this, they are in use by the vast majority of email providers, and as far as I can tell, there are no functional or security disadvantages to using SSL over 993/995 - instead of STARTTLS over 110/143.
