I recover the signature of an account:

zmprov ga source@mydomain.com | grep zimbraPrefMailSignatureHTML

output:

zimbraPrefMailSignatureHTML: <img dfsrc="doc:Briefcase/mailing.jpg" style="border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; ">

Then I would like insert this HTML signature into another account:

zmprov ma destination@mydomain.com zimbraPrefMailSignatureHTML "<img dfsrc="doc:Briefcase/mailing.jpg" style="border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; ">"

But, I have problem with ' " ', because the signature have simbol " into the code... If try with '

zmprov ma destination@mydomain.com zimbraPrefMailSignatureHTML '<img dfsrc="doc:Briefcase/mailing.jpg" style="border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; ">'

Don't work...

Any idea to copy an html signature from an account to another account??

Thx
