When a user emailed one of our customers, this line came up in the logs: Mar 2 15:43:22 mailgate postfix/smtp[4830]: 89423170093: to=<u...@domain.com>, relay=domain.com.inbound15.mxlogicmx.net[208.65.144.13]:25, delay=1.4, delays=0/0/0.27/1.2, dsn=2.0.0, status=sent (250 Backend Replied [dc87d8b4.0.970491.00-043.1797288.p02c11m002.mxlogic.net]: 2.6.0 <EE1E78EDBC0F984898CC3246012C60D13)
After searching on Google, there seemed to be others asking the same question as me however I couldn't find a definite answer. Many of them were talking about emails not getting delivered. What does "250 Backend Replied" mean? Should I be worried about this?
