This is happening a lot since I switched from Courier to Dovecot and when the 11.40 version happened.

I need to know how to fix this issue because it affecting the incoming email of my customers.


Reason: TCP Transaction Log:
<< * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE NAMESPACE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready.
>> A001 LOGIN __cpanel__service__auth__imap__f5iPn_CjJWCFYMKHfTD4RvtSOvW_YLjgahb2lLk_PWeqISEvvdtoMaQ_GJ6H_yAP yGd6HwQlClHySwX11RiMxdV0qNwX3jc6ZOtLsPGd7yVe3Vnp5bXRNZAZsORmhQ2T

To update, it looks like this issue was resolved adjusting the following values in "WHM Home » Service Configuration » Mailserver Configuration":

Maximum Size of a Authentication Process (MB) to 128M
Maximum Number of Authentication Processes to 70

Thank you.
