Nagios Support Forum

now the email is working fine, i will create smtp server with nagios.
Thanks for your help

According to google docs it seems that 2000 emails per day. we are not crossing the limit of emails.

can you please suggest me the alternate relay option rather than relay=aspmx.l.google.com

kindly tell me alternate MTA for email sending

hi i have receive only one email of Cam 53 dowm. kindly check the logs maillog file Mar 23 17:49:03 in-nagios sendmail[3948]: STARTTLS=client, relay=aspmx.l.google.com., version=TLSv1/SSLv3, verify=FAIL, cipher=AES128-GCM-SHA256, bits=128/128 Mar 23 17:49:05 in-nagios sendmail[3948]: w2NCJ0XL003946:...
