Topic: X-Supplementary-Info: < #5.4.7 smtp; 554 5.4.7 [internal] exceeded max
Hi, I have a situation. Many of our clients tell me that the emails they send us after approximately 2 hours return the following message:
Reporting-MTA: dns; mail.bancodeoccidente.com.co
Final-recipient: RFC822; firstname.lastname@example.org
X-Supplementary-Info: <# 5.4.7 smtp; 554 5.4.7 [internal] exceeded max time
Please your help to verify if the problem is ours or not.
Thanks a lot.
