hopefully they pay for that "cosmetic reasons" or leave technical things to techs
keep in mind that you need a certificate with each used domain as SAN (subject
alternative name) which means each time you host a new domain you need to change
the certificate - Thawte calculates 169,- per jear and SAN - have fun :-)
then there are mail-clients - which of them do not support SNI, or in case
of mail clients which of them do support it properly and how is the
presentability in case of certificate warnings for the one which does not
169,- for cosmetic reasons - well, i would prefer a chiropody instead.....
