If the mail server goes down or if a network error occurs during connection to the mail server or during email sending, the mail adapter retries to connect to the mail server until the mail server connection timeout expires. You can also set the email send timeout, which is the time that can elapse before email sending fails.

The following table shows the parameters you can set.

Table 2-15 Mail server connection timeout and email sending timeout settings

Value	Key name	Default value
Mail server connection timeout (seconds)	mailadp.smtp.connectiontimeout	180
Email sending timeout (seconds)	mailadp.smtp.timeout	180

When sending an email message with an attachment, if you access the path to an attachment in the common folder specified in the request message, a shared lock is set for the specified file.

A shared lock is not set if you specify the work folder in the request message or if you access the path to a file specified in the mail adapter runtime environment property file.

For exclusive management timeout, you can set the lock retry frequency and the retry interval used if the mail adapter fails to acquire the shared lock.

The retry status that exists when the mail adapter fails to acquire the shared lock is output to the maintenance log. For details about the maintenance log, see 7.3.1 How to acquire log or trace output by Cosminexus Service Platform in the Service Platform Setup and Operation Guide.

The following table shows the parameters you can set.

Value	Key name	Default value

Lock retry interval (seconds)	mailadp.read-lock.retry.interval	1
