External Account Failure after domain transfer

Hi guys , I have a problem with a Zimbra server 8.0.2_GA_5569 (build 20,121,210,115,059 ) :confused:
Everything worked until the transfer of the domain ( www.xxx.com ) on the new server.
Since the e-mail management was transferred to the new server , the :mad: (POP3 connector) stopped working and gives me the following error:

system failure: Unable to connect to POP3 server: LdapDataSource{id=6fa3434d-1b89-40f3-bf53-137ad47e3e74, type=pop3, enabled=true, name=info@xxx.com, host=mail.xxx.com, port=110, connectionType=cleartext, username=info@xxx.com, folderId=2}, java.security.cert.CertificateException: d2:CN15:Parallels Panel1:O9:Parallels2:OU15:Parallels Panel6:accept4:true5:alias31:mail.xxx.com:4DBACCB8 4:fromi1304087736000e4:host22:mail.xxx.com3:icn15: Parallels Panel2:io9:Parallels3:iou15:Parallels Panel3:md532:CE9F5926CF4E3A5937ED3854337BB14D8:mis match5:false1:s8:4DBACCB84:sha140:DBF9B4F78F43F1B8 4BA3435B8B47BF30C2F6B2DF2:toi1335623736000ee, d2:CN15:Parallels Panel1:O9:Parallels2:OU15:Parallels Panel6:accept4:true5:alias31:mail.xxx.com:4DBACCB8 4:fromi1304087736000e4:host22:mail.xxx.com3:icn15: Parallels Panel2:io9:Parallels3:iou15:Parallels Panel3:md532:CE9F5926CF4E3A5937ED3854337BB14D8:mis match5:false1:s8:4DBACCB84:sha140:DBF9B4F78F43F1B8 4BA3435B8B47BF30C2F6B2DF2:toi1335623736000ee

login credentials are correct .. I also tried to delete the account and recreate it but the error is always the same ... have an idea of ​​how to solve?

Thanks to all of the aid
