Send name wrong although changed in the config

Send name wrong although changed in the config

I used to use google apps to the emails of my small company and now I'm moving to ZOHO. \0/

I did all changes in CNAME, MX Records, etc. but my "From"-name is still showing the one I had on google!?

My "From"-name on google was Douglas B.P.Silva. In ZOHO's configurations I've changed it to Douglas Silva, but when I send e-mails now using ZOHO people are seeing the old one. I double checked the configuration and everything seems to be OK.

Does it has something to do with the DKIM or SPF entries that I configured before creating this user?

Where I should change my "From"-name otherside than in the configs or https://accounts.zoho.com/u/h#profile/personal?

Many thanks in advance!
