phpmailer stop working server wide.

[rebouy]

phpmailer has stop working in the whole server for many clients.

this is a sample of the exim_mainlog, only changed the real sending and receiving account.
Just changing the sending script in one client to use an account in another server and everything works. Its only a server issue and not a script issue (it was working, stop working for more than 1 client, and it works w an account in a different server)

Does the domain use SMTP authentication for the script to connect? Are these accounts working for logging into Webmail and sending emails via Horde or Roundcube? This error appears to indicate there might be an authentication issue for the script from what I can see.
