Hai,

Im from Indonesia, sorry for my bad english

First of all, im new for zimbra and sorry if this topics already been post to this forum, but i already browsing for more than 5 hours to solved this problem but i still cant do.
So my problem is everyone in my company is using outlook as mail receiver. we are using POP and SMTP. the ISP gave us the smtp address with the outgoing server authentication.

We just been moved to new industrial area and were changing from A isp to B isp, A isp do not need any authentication for outgoing mail, but B is gave us different smtp address and also using authentication.
Previously the email is never be a problem, but after using the authentication method, the email is become slow to receive even with the internal domain.
and now is totally cannot send email.

this is the log :
