&lt;h2&gt;Symptoms&lt;/h2&gt;
&lt;p&gt;A &lt;a href="https://docs.appian.com/suite/help/latest/Mail_Server_Setup.html"&gt;mail server&lt;/a&gt; is set up to be used with Appian. Appian is configured for either:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;SMTP server authentication, with&amp;nbsp;&lt;code&gt;conf.mailhandler.mail.smtp.auth=true&lt;/code&gt; in &lt;strong&gt;custom.properties&lt;/strong&gt;.&lt;/li&gt;
&lt;li&gt;&lt;a href="https://docs.appian.com/suite/help/latest/Mail_Server_Setup.html#receiving-emails"&gt;Email Polling&lt;/a&gt;.&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;When configured for SMTP server authentication, the following error message is seen in the application server log:&lt;/p&gt;
&lt;pre&gt;ERROR com.appiancorp.process.runtime.activities.SendEmailActivity - javax.mail.AuthenticationFailedException: 535 5.7.8 Error: authentication failed: authentication failure&lt;/pre&gt;
&lt;p&gt;When&amp;nbsp;configured for polling an email account,&amp;nbsp;the following error message is seen &lt;strong&gt;mail-listener.log&lt;/strong&gt;:&lt;/p&gt;
&lt;pre&gt;ERROR com.appiancorp.process.emailpoller.MailActivation - An error occurred while attempting to open the mailbox to poll; no mail will be fetched. &lt;br /&gt;javax.mail.AuthenticationFailedException: Authentication failed.&lt;/pre&gt;
&lt;p&gt;The following are both true when configured for SMTP server authentication:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;The SMTP username,&amp;nbsp;&lt;code&gt;conf.mailhandler.mail.user&lt;/code&gt;, in &lt;strong&gt;custom.properties&lt;/strong&gt; is correct.&lt;/li&gt;
&lt;li&gt;The associated password,&amp;nbsp;&lt;code&gt;conf.password.SMTP&lt;/code&gt;, in &lt;strong&gt;password.properties&lt;/strong&gt; is correct.&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;The following are both true when configured for polling an email account:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;The email username &lt;code&gt;conf.mailhandler.poller.EmailHandlerBean.userName&lt;/code&gt; in &lt;strong&gt;custom.properties&lt;/strong&gt; is correct.&lt;/li&gt;
&lt;li&gt;The associated password &lt;code&gt;conf.password.EmailHandlerBean.EMAIL_HANDLER&lt;/code&gt; in &lt;strong&gt;password.properties&lt;/strong&gt; is correct.&lt;/li&gt;
&lt;/ol&gt;
&lt;h2&gt;Cause&lt;/h2&gt;
&lt;p&gt;Some special characters within &lt;strong&gt;password.properties&lt;/strong&gt; need to be escaped when used in:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;The STMP password field,&amp;nbsp;&lt;code&gt;conf.password.SMTP&lt;/code&gt;&lt;/li&gt;
&lt;li&gt;The email user password field,&amp;nbsp;&lt;code&gt;conf.password.EmailHandlerBean.EMAIL_HANDLER&lt;/code&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;The characters which need to be escaped may vary depending on the mail server being used. For example, it is known that the character &lt;code&gt;,&lt;/code&gt; needs to be escaped.&lt;/p&gt;
&lt;h2&gt;Action&lt;/h2&gt;
&lt;p&gt;If&amp;nbsp;it is determined a special character needs to be escaped, add the characters &lt;code&gt;\\&lt;/code&gt; in front of the special character.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;E.g.&amp;nbsp;&lt;code&gt;conf.password.SMTP=password\\,example&lt;/code&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;Some special characters do not need to be escaped.&amp;nbsp;To test if a special character needs to be escaped when authentication is failing:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Change the password to remove the special character in question.&lt;/li&gt;
&lt;li&gt;If authentication is successful without the special character, re-add the special character and escape it with &lt;code&gt;\\&lt;/code&gt;.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Some special characters within &lt;strong&gt;password.properties&lt;/strong&gt; need to be escaped when used in:&lt;/p&gt;

&lt;p&gt;For example, it is known that the character &lt;code&gt;,&lt;/code&gt; needs to be escaped.&lt;/p&gt;

&lt;p&gt;If&amp;nbsp;it is determined a special character needs to be escaped, add the characters &lt;code&gt;\\&lt;/code&gt; in front of the special character.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;E.g.&amp;nbsp;&lt;code&gt;conf.password.SMTP=password\\,example&lt;/code&gt;&lt;/li&gt;

&lt;p&gt;However, some special characters do not need to be escaped. If it is unsure if a special character needs to be escaped:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Change the password to remove the special character in question.&lt;/li&gt;
&lt;li&gt;If authentication is successful without the special character, re-add the special character and escape it with &lt;code&gt;\\&lt;/code&gt;.&lt;/li&gt;

&lt;h2&gt;Symptoms&lt;/h2&gt;
&lt;p&gt;An&amp;nbsp;SMTP server is set up to be used with Appian. Appian is configured for either:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;SMTP server authentication, with&amp;nbsp;&lt;code&gt;conf.mailhandler.mail.smtp.auth=true&lt;/code&gt; in &lt;code&gt;custom.properties&lt;/code&gt;.&lt;/li&gt;
&lt;li&gt;Polling an email account.&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;When configured for SMTP server authentication, the following error message is seen in the application server log:&lt;/p&gt;
&lt;pre&gt;ERROR com.appiancorp.process.runtime.activities.SendEmailActivity - javax.mail.AuthenticationFailedException: 535 5.7.8 Error: authentication failed: authentication failure&lt;/pre&gt;
&lt;p&gt;When&amp;nbsp;configured for polling an email account,&amp;nbsp;the following error message is seen &lt;code&gt;mail-listener.log&lt;/code&gt;:&lt;/p&gt;
&lt;pre&gt;ERROR com.appiancorp.process.emailpoller.MailActivation - An error occurred while attempting to open the mailbox to poll; no mail will be fetched. &lt;br /&gt;javax.mail.AuthenticationFailedException: Authentication failed.&lt;/pre&gt;
&lt;p&gt;The following are both true when configured for SMTP server authentication:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;The SMTP username,&amp;nbsp;&lt;code&gt;conf.mailhandler.mail.user&lt;/code&gt;, in &lt;code&gt;custom.properties&lt;/code&gt; is correct.&lt;/li&gt;
&lt;li&gt;The associated password,&amp;nbsp;&lt;code&gt;conf.password.SMTP&lt;/code&gt;, in &lt;code&gt;password.properties&lt;/code&gt; is correct.&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;The following are both true when configured for polling an email account:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;The email username &lt;code&gt;conf.mailhandler.poller.EmailHandlerBean.userName&lt;/code&gt; in &lt;code&gt;custom.properties&lt;/code&gt; is correct.&lt;/li&gt;

&lt;li&gt;The email user password field,&amp;nbsp;&lt;code&gt;conf.password.EmailHandlerBean.EMAIL_HANDLER&lt;/code&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;Appian is aware that the character &lt;code&gt;,&lt;/code&gt; needs to be escaped in the &lt;code&gt;conf.password.SMTP&lt;/code&gt; field.&lt;/p&gt;
&lt;h2&gt;Action&lt;/h2&gt;
&lt;p&gt;If&amp;nbsp;it is determined a special character needs to be escaped, add the characters &lt;code&gt;\\&lt;/code&gt; in front of the special character.&lt;/p&gt;
