MSMTP logs storage

MSMTP logs can always be reviewed for sent emails-related errors. Such logs are located at this directory: /home/bitrix/.

Each individual site has its dedicated MSMTP log, with log name containing site name – msmtp_{SiteName}.log. For example, default site will have the name msmtp_default.log.

Important! SMTP services can have custom limits for sending email campaigns and can limit such campaigns up to complete blocking of email account used for email campaigns.

For example, Google has a default limit for emails: 500 emails per 24 hours. When an email has several recipients, each email is deemed as separate email. This daily limit can change based on service custom algorithms for calculation user credibility.
