Alert email error -- what is the message size limit and where to change the limit?

[sbbadri]

I got below error message while sending alert as a email only to a particular saved search.

09-25-2017 06:00:45.331 -0400 ERROR ScriptRunner - stderr from '/opt/splunk/server/bin/python /opt/splunk/server/etc/apps/search/bin/sendemail.py "results_link=https://XXXXXXXXXXXXXX:8000/app/search/@go?sid=xxxxxxxxxxxx" "graceful=True" "trigger_time=1506333632" results_file="/opt/splunk/server/var/run/splunk/dispatch/sxxxxxx/results.csv.gz"': ERROR:root:(552, '5.3.4 Message size exceeds fixed limit', u'no-reply@xxxxxxx') while sending mail to: xxxxx.com;xxxxx.com;xxxxx.com; xxxx.com;xxxx.com

what is the message size limit and where to change the limit.

Hi DalJeanis,

i found the issue, splunk is triggering the alert properly. It got stuck in email gateway where size defined is 20MB. Attachment is exceeds over 20MB, so that alert triggered from splunk is getting blocked.
