We have a zimbra server, Release 7.1.3_GA_3346.DEBIAN5_64, with 200 accounts.
We run a script to set up a zimbraPrefMailSignatureHTML to web link in the same server.
Ex.: Our server have a hostname server.company.com, the zimbraPrefMailSignatureHTML is server.company.com:7780/Signaturesemail@example.com
Sometimes webmail puts the correct signature, sometimes not.
If I try to open per browser the link of the signature, the image opens all times.
Thanks a lot!
