Call objects getting SMTP rejection

Some of our call objects randomly get the SMTP rejection error (U00050006 SMTP server '' has rejected the E-mail command: '<SMTP address>') or time out error (U00050012 Timeout - SMTP Server '<SMTP address>' did not answer within '20' seconds). 
It happen on different objects at different time. E.g. on Nov 21, 3 objects got the smtp rejection error at 10:42:26 pm, 8:00:42 pm, 4:07:44 am and a time out at 1:34:06 pm. 

We are using the cloud host for routing the emails. 

Just wondering if someone else is getting similar issue and what can be done to resolve it. 

Thank you.
